How to Streamline Your Email Marketing Campaign Process | Checklist
Step 1: Set Clear Campaign Goals and KPIs
Before you even start drafting an email campaign, you need to define your goals. Without clear goals, your efforts can feel like throwing darts in the dark - you might hit something, but you’ll never know if it’s what you intended.
Start by aligning your email campaign objectives with your overall business goals. This approach isn’t just good practice - it’s essential. According to research, 90% of marketing leaders are more focused on tying their efforts to business objectives than they were five years ago [2] . And when done strategically, email marketing can deliver an incredible 4,400% ROI [6] .
Identify Your Primary Objective
The first step is pinpointing your main campaign goal. Most email campaigns fall into one of four categories: lead generation, brand awareness, customer engagement, or sales conversions [1] . For example:
A lead generation campaign might encourage users to download a free resource (like an eBook or whitepaper).
A sales-focused campaign could aim to nudge subscribers toward making a purchase.
Whatever your goal, make it SMART - Specific, Measurable, Achievable, Relevant, and Time-bound [3][5] . Instead of saying, “increase engagement,” aim for something like, “boost click-through rates by 15% over the next 30 days.” Defined goals like this create clarity, guide your team, and help you choose the right metrics.
"Good marketing makes the company look smart. Great marketing makes the customer feel smart." - Joe Chernov [1]
Choose the Right KPIs
Once you’ve set your goals, it’s time to decide how you’ll measure success. Your KPIs should directly tie back to your objectives. For instance:
A common mistake is focusing too much on vanity metrics - numbers that look impressive but don’t provide meaningful insights. Harvard Business School Professor Sunil Gupta highlights this issue:
"It isn't enough to measure the final outcome alone. You also need to track intermediate metrics to understand where consumers might be getting stuck - essentially bottlenecks in the marketing funnel." [10]
Set Realistic Benchmarks
When setting benchmarks, consider how your audience behaves. Industry averages are a helpful starting point, but your audience may not align with them. For instance, a B2B software company targeting CTOs will likely see different engagement trends than an e-commerce brand selling consumer goods. Use your historical data to set realistic, incremental improvement goals rather than aiming for dramatic leaps.
And don’t overlook your email list’s health. On average, email lists shrink by 22.5% annually due to natural churn [2] . To offset this, aim for a monthly growth rate of around 2.5% [7] .
Get Your Team on the Same Page
Lastly, make sure everyone involved in the campaign is aligned on the goals. From copywriters to designers to data analysts, everyone should understand what success looks like. This alignment prevents missteps - like the creative team focusing on engagement metrics while the business team expects sales results.
With clear goals and KPIs in place, you’ll have a solid foundation for the rest of your campaign planning. Every decision you make moving forward - from audience segmentation to subject line testing - should directly support these objectives. Now, it’s time to fine-tune your audience segmentation in the next step.
Step 2: Check Your Audience Segmentation
Once you've nailed down your campaign goals, the next step is making sure your message lands with the right audience. Segmentation is what separates emails that get opened from those that go straight to the trash. And here's a stat to prove it: businesses can boost email marketing revenue by 760% just by using segmentation [12] .
Think about it this way - you wouldn't send the same party invite to a kindergartner and a college buddy, right? The same principle applies to your email campaigns. Segmented email campaigns achieve 14.31% higher open rates compared to non-segmented ones [16] . On the flip side, 56% of people unsubscribe because the content doesn’t resonate with them [13] .
Start with Your Data Foundation
Before diving into segmentation, take a good hard look at your data. Most businesses gather insights through sign-up forms, purchase histories, website behavior, and surveys. But remember, email lists naturally shrink by around 22.5% each year [14] , so keeping your data fresh and accurate is critical.
Segmentation data typically falls into three main buckets:
Demographic data: Think age, gender, location, job title, or income.
Behavioral data: This includes purchase history, website activity, and email engagement.
Lifecycle stage: For example, differentiating between new subscribers, active customers, or those at risk of churning [11] .
The key here? Collect data that you can actually use to tailor your campaigns.
"Email segmentation is the simplest way to ensure you're sending the right message to the right person at the right time. You don't need any technical skills to create segments of your audience, either. Most - if not all - ESPs will give you that feature out-of-the-box. The only thing you need to decide is what segments you want to create."
Review Your Current Segments
Take a moment to reassess your existing segments. Are they still hitting the mark? While 78% of marketers use email segmentation [16] , many set it up once and then forget about it. But your audience changes over time, and your segments should evolve with them.
Want inspiration? Check out how some big names are doing segmentation right:
Disney tailors emails to Florida residents who are Annual Passholders, offering them park-specific updates and surveys [11] .
Groupon uses location data to deliver deals that are relevant to a subscriber's area [11] .
Sephora rewards its top-tier loyalty members with early access to new products [11] .
These brands show how leveraging specific data points can create highly personalized and meaningful experiences.
Avoid Common Segmentation Mistakes
Segmentation can make or break your email campaigns, but it’s easy to get it wrong. In early 2024, Zettler Digital audited 65 Klaviyo email accounts and found segmentation issues were a major drag on performance [17] . The most frequent mistakes? Over-segmenting, under-segmenting, and collecting data that never gets used.
Over-segmentation: This happens when you create so many tiny groups that they become ineffective.
Under-segmentation: On the flip side, being too broad means your emails still feel generic.
The sweet spot? Segments that are big enough to matter but specific enough to feel relevant.
Test Your Segments Before Launch
Before you hit "send", double-check your segments. Do they align with your campaign goals? For instance, promoting a winter coat sale to subscribers in Florida probably isn’t the best move. If you’re rolling out a new feature, focus on your most engaged users first.
Here’s why this matters: relevant emails generate 18x more revenue than generic broadcasts [13] . Plus, 96% of organizations believe personalization can improve email performance and conversions [13] . When you verify your segments upfront, you’re setting yourself up to maximize every opportunity. With your segmentation locked in, you’re ready to move on to campaign testing.
Step 3: Test All Personalization Fields
Once you've defined your segments, it's time to ensure every personalized detail in your email is spot-on. Why? Because default merge tags can ruin the entire point of personalization. Mistakes like these are more common than you'd think, and they can seriously harm your brand's reputation.
Here’s the truth: emails tailored to a recipient’s specific needs perform six times better than generic ones [18] . Even more impressive, personalization can boost email click-through rates by 139% [18] . But when personalization goes wrong - like addressing someone as "Dear [FIRST_NAME]" - it sends a clear message that you don’t actually know your audience. That’s a trust-breaker.
This step is essential for ensuring error-free dynamic content in your emails.
The Real Cost of Personalization Errors
Personalization is a big deal in email marketing - 94% of marketers say it’s "extremely important" for achieving their goals [18] . But when done poorly, it can backfire in a big way. As IndustrySelect puts it: "Personalization mistakes are almost always the result of poor-quality data" [18] . In other words, bad data equals bad results. And it doesn’t just hurt your campaign; it damages your credibility.
Think about this scenario: you’ve spent hours perfecting your message, but your email starts with "Dear [COMPANY_NAME] Team" instead of "Dear Acme Corp Team." Just like that, you’ve lost credibility - and probably the recipient’s attention.
Test Every Dynamic Field Before Launching
To avoid these pitfalls, create a test group that includes a variety of data scenarios. For instance:
Recipients with no last name
Companies with unusually long names
Fields that might be empty or incomplete
This way, you can see how your email looks in every possible situation. For example, does it still read smoothly if someone only has a first name? Does the formatting hold up when a company name is extra long? Testing these variables ensures your email stays polished no matter what.
IndustrySelect emphasized that their data is thoroughly researched and verified, ensuring variables like names, titles, and company details are accurate and complete. This allows marketers to focus on crafting great messages instead of worrying about data errors [IndustrySelect Blog, 2024]. It’s a reminder of how critical clean data is for seamless personalization.
Also, watch out for formatting issues. Encoding errors - like stray brackets or inconsistent capitalization - can make even the most professional email look like spam. Double-check that every field pulls from the correct data source.
Create Real-World Preview Scenarios
Don’t just rely on perfect data during testing - that’s not how things work in the real world. Set up preview scenarios that include edge cases, such as:
Hyphenated names
Companies with special characters
Contacts missing key details
These scenarios help you catch potential problems before your email hits inboxes. Even if your email platform offers merge tag previews, send actual test emails to yourself or your team. This lets you see how the email displays across different devices and clients like Gmail or Outlook. Sometimes what looks perfect in a preview can break when viewed elsewhere.
Once you’ve ensured your emails display correctly, keep things running smoothly with regular data maintenance.
Keep Your Data Clean and Current
IndustrySelect highlights that their data is regularly updated and verified for accuracy, ensuring clean, polished emails every time while avoiding embarrassing encoding errors [IndustrySelect Blog, 2024]. This underscores a key point: your personalization is only as good as the data behind it.
Make data hygiene a regular habit. Remove outdated entries, standardize formatting, and validate new data as it comes in. Conditional merge tags can also save the day - use them to display fallback content when key fields are empty. For example, if a recipient’s first name is missing, you could default to "Hello there" instead of "Hello [FIRST_NAME]."
Double-Check Before Hitting Send
Before you send, take a final look at every personalization field. Remember, personalized emails can increase click-through rates by 139% compared to static ones [19] . But this only works if everything is set up correctly. Taking a few extra minutes to verify your fields can save you from costly mistakes - and help boost your open rates and reputation.
With your personalization fields thoroughly tested, it’s time to move on to the next step: crafting subject lines that grab attention and drive engagement. Let’s dive into that next.
Step 4: Test Subject Lines and Preview Text
After fine-tuning personalization, the next step is crafting an email envelope that grabs attention and drives engagement. The subject line and preview text are the first things recipients notice, and they play a huge role in determining whether your email gets opened. In fact, 47% of users decide to open an email based solely on the subject line [21] , while 24% rely on the preview text [24] . This makes testing both elements together a critical step in creating a successful email campaign.
The key is to ensure your subject line and preview text work together seamlessly. The subject line should grab attention, while the preview text provides additional context to encourage recipients to take action.
Set Up Effective A/B Tests for Subject Lines
A/B testing is a simple yet powerful way to find out which subject lines resonate best with your audience [20] . Start by defining a clear goal - whether you're aiming to increase open rates, clicks, or conversions [20] . To get meaningful results, test only one variable at a time, such as length, tone, personalization, or urgency. Also, make sure your audience is segmented properly so you have a big enough sample size to draw reliable conclusions [20] .
"A/B testing subject lines is not just a marketing tactic - it's a data-driven approach to maximizing engagement and conversions. Every well-crafted test can give you important insight into your specific audience. By consistently testing, analyzing, and iterating, you can discover what resonates most with your audience."
Alex Killingsworth, Email & Content Marketing Strategist, Online Optimism [20]
Craft Preview Text That Complements Your Subject Line
Your preview text is valuable real estate - don’t waste it by repeating your subject line. Instead, use it to add context or expand on the subject line's message [24] . Think of it as the second half of a conversation starter.
Keep the preview text concise, ideally under 60–80 characters, so it displays properly on most devices [23][24] . While guidelines suggest a range of 40 to 140 characters [23] , shorter tends to work better, especially for mobile users.
Here are a few examples of brands that nail this:
H&M: Subject line: "Free Shipping over $25 is a real treat! 🍬"
Preview text: "Not a member? Join for free today!"
This pairing highlights a benefit and includes a clear call-to-action [23] .The Natori Company: Subject line: "4 Days Only: 30% Off Fall Favorites"
Preview text: "Use code COZY at checkout."
The urgency in the subject is matched with practical details in the preview [23] .MasterClass: Subject line: "My class on building a winning mindset is here"
Preview text: "I want to help you overcome your fear and unlock your true potential."
This combination creates a personal and motivational tone [23] .
By aligning your subject line and preview text, you create a compelling "email envelope" that encourages recipients to open and engage.
Test Both Elements Together for Maximum Impact
While testing subject lines and preview text separately can provide insights, testing them as a unit often yields better results. Together with the sender name, these elements form the complete "email envelope", which is responsible for making a strong first impression [25] .
Experiment with different combinations to see what works best. For example, some audiences may respond to curiosity-driven subject lines paired with benefit-focused preview text, while others may prefer a straightforward approach with a sense of urgency.
Avoid Spam Triggers and Focus on Deliverability
Even the most engaging subject line is useless if it lands in the spam folder. Avoid using spam trigger words like "FREE", "URGENT", or "LIMITED TIME", and steer clear of excessive punctuation [22][24] . Instead, use action-oriented language that creates a sense of urgency or curiosity without sounding overly promotional.
Another tip: Use a real person's name as the sender. Emails from individuals often feel more personal and trustworthy, and this simple change can boost open rates by up to 50% [21] .
Analyze Results and Apply Insights
Once your tests have run for 24–48 hours, dive into the data. Track metrics like open rates, click-through rates, and conversions [20] . But don't stop at open rates - a high open rate with low engagement suggests there's room for improvement. Look for patterns: Do your subscribers respond better to questions or statements? Are numbers more effective than general claims? These insights will help guide your future campaigns.
In 2023, average email open rates range from 18% to 44%, depending on the industry [21] . By continuously testing and refining your subject lines and preview text, you can work toward achieving open rates at the higher end of this spectrum.
Once you've perfected your email envelope, shift your focus to ensuring the email content delivers on the promises made. After all, a strong first impression is only the beginning.
Step 5: Proofread Your Email Content
Now’s the time to make sure your email content truly delivers on its promise. This step is about perfecting the quality you’ve worked hard to achieve through earlier testing and segmentation. Even a single typo can hurt your credibility and impact results. For instance, web pages with typos experience an 85% higher bounce rate than error-free pages [31] . Start by reviewing the overall flow, then dive into the finer details.
Proofreading isn’t just about fixing spelling mistakes. It’s about ensuring your message is clear, your tone matches your brand, and every word works toward encouraging your audience to take action.
Start with the Big Picture, Then Zoom In
Begin by evaluating the overall structure and flow of your email. Does the message align with your campaign goals? Does it deliver on the promise made in your subject line? Is your call-to-action clear and persuasive?
Once you’re confident in the big picture, focus on specific types of errors. Review spelling, grammar, and punctuation one at a time [28] . Tackling errors systematically makes it easier to catch mistakes you might otherwise miss.
"Proofreading your email marketing content is an essential step in ensuring the success of your campaigns. By taking the time to proofread, you can improve your open and click-through rates, avoid any potential legal problems, and make sure that your message is clear and concise." - Taktical Team [26]
Read Aloud and Take Breaks
Reading your email out loud is a powerful way to catch awkward phrasing or clunky sentences that might slip past your eyes [26] . Hearing the words can help you determine if your tone feels natural and conversational. Also, step away for a bit before proofreading - returning with fresh eyes can make a big difference.
Focus on Critical Details
Certain parts of your email need extra attention. For example, names and pronouns are key to personalization - misspelling a name can ruin the connection you’re trying to build. Double-check merge fields to ensure they’re pulling the correct information.
Your subject line, often the first thing recipients see, deserves another look - even if you’ve tested it earlier. Test every link and attachment manually to confirm they work as intended. Finally, verify all facts, dates, and statistics to ensure accuracy.
Simplify Your Message
Good proofreading often involves trimming unnecessary content. Emails written at a third-grade reading level tend to perform better [32] , so aim for simplicity and clarity.
"Good editing is about taking things away - like extra words or unnecessary sentences - rather than adding." - Lauren Haas, Consultant [27]
Cut filler words, remove redundant phrases, and replace weak verb-adverb combinations with stronger verbs. If a sentence doesn’t directly support your main message or call-to-action, consider cutting it.
Use Tools, But Don’t Rely on Them Alone
Grammar and spell-check tools are helpful for spotting obvious errors, but they’re not perfect. Tools like Grammarly (starting at $29.95/month), ProWritingAid ($20/month), or the free Hemingway Editor can highlight potential issues. However, human judgment is irreplaceable when it comes to tone and clarity.
Get a Second Opinion
A fresh set of eyes can catch errors you might overlook. Ask a colleague for feedback on clarity, tone, and overall flow. If you’re working solo, try reading your email backward - sentence by sentence. This technique forces you to focus on each sentence individually, making it easier to spot typos and grammatical mistakes.
Match Your Tone to Your Brand Voice
Make sure your tone reflects your brand personality, whether it’s friendly, professional, or authoritative. Sixty-four percent of customers want brands to connect with them on a personal level [29] , and consistent brand presentation has been shown to increase revenue by 33% [30] .
Test Formatting Across Devices
Formatting can make or break your email’s appearance. What looks perfect in your editor might display differently on various devices or email clients. Check for issues like uneven spacing, awkward line breaks, and overall layout on both desktop and mobile. Also, ensure your email doesn’t come across as too brief or cold [32] . Your recipients should have enough context to understand your message, and your call-to-action should be easy to find and act on.
Once your content is polished, you’re ready to move on to technical testing.
Step 6: Test All Links and CTAs
Before hitting "send" on your email campaign, double-check every clickable element to ensure everything works as intended. A single broken link or misdirected call-to-action (CTA) can derail the user experience you've worked hard to create. If a recipient clicks on a link that doesn’t work, they’re unlikely to trust your emails again.
Start by manually testing every link, button, and interactive element. Send yourself a test email and click through each component. This hands-on approach often catches mistakes that automated tools might overlook. For instance, imagine a prominent CTA leading to a 404 error page - catching this issue during testing can save your campaign from disaster [34] .
Next, verify that every link directs users to the correct destination. Whether it’s a landing page, sign-up form, blog post, or product page, the link should match its description. For example, if your button says "Download Free Guide", it should lead users straight to that guide. Don’t forget to add UTM parameters to track link performance. These parameters provide valuable insights into user behavior. For example, Litmus uses UTM tags like "utm_content=hero" for their hero image link, allowing them to monitor how readers interact with specific elements in their emails [33] .
Make sure your email is mobile-friendly. With 44.7% of email opens happening on mobile devices, it’s crucial that links and buttons work seamlessly on smaller screens [33] . Apple suggests touch targets should be at least 44x44 pixels to ensure easy tapping [33] . Double-check that your CTAs are large enough and spaced appropriately for mobile users.
Use tools like Litmus or Email on Acid to validate links and check for other issues, such as broken images or accessibility problems [34] . SendGrid also offers features that ensure every link and button in your email functions as expected [35] . For evergreen campaigns or automated sequences, consider implementing 24/7 link monitoring to catch broken or slow-loading links before they affect your audience [33] .
Experiment with different CTA designs and formats. For example, Campaign Monitor discovered that using a green button instead of a text link increased click-through rates by 28% [36] . Similarly, action-oriented CTA copy can lead to a 10% boost in clicks - phrases like "Get Your Free Report" often outperform generic options like "Click Here" [37] .
Ultimately, broken or poorly functioning links can hurt both your conversions and your reputation. By thoroughly testing every clickable element, you protect your campaign’s success and ensure a better experience for your audience.
Once your links and CTAs are fully tested, it’s time to focus on optimizing your email for flawless mobile performance.
Step 7: Check Mobile Display
How your email performs on mobile devices can make or break your campaign. With over 60% of emails now opened on smartphones and tablets instead of desktops [42] , ensuring your messages display flawlessly on smaller screens is non-negotiable. Mobile users also check their email three times more often than desktop users [43] .
"Mobile isn't the future of email marketing - it's the present. Companies still treating mobile optimization as optional are essentially sending unread messages straight to the trash folder."
Maya Reynolds, Digital Strategist [43]
Start by testing your email on various devices and screen sizes. Don’t assume that what looks great on your desktop will translate well to a smartphone. For example, with Apple’s iOS Mail holding nearly 40% of the market share among email clients [38] , ensuring compatibility with Apple devices is especially important.
Your email service provider likely offers a preview tool to check how your email renders on different devices. These built-in tools simulate various screen sizes and email clients, but for a more thorough review, consider using third-party testing platforms. Tools like Email on Acid (starting at $74/month) or Litmus (starting at $99/month with a 7-day free trial) provide advanced testing options [41] . If you’re on a tight budget, PutsMail offers free testing capabilities [41] .
When optimizing for mobile, focus on a clean, functional design. Stick to a single-column layout with a width between 600 and 640 pixels [38] . This format supports natural scrolling and eliminates the need for frustrating horizontal navigation. Pay close attention to text and interactive elements: use a font size of at least 14 pixels for readability (the minimum size displayed on iPhones is 13 pixels) [38] , and ensure call-to-action buttons have a tappable area of at least 44 x 44 pixels [38] .
Campaign Monitor advises a mobile-first approach:
"When designing your emails, you should start with a mobile design, because if it looks good in a mobile view, it's going to look great on desktop" [38] .
This strategy ensures your key content is front and center, with design elements scaling effectively across all devices.
Don’t forget about images. Compress them to improve load times on mobile networks and include alt text so your message remains clear even if the images don’t load properly [39] . A faster, cleaner design can lead to impressive results - To'ak Chocolate, for instance, saw a 394% increase in their conversion rate in 2024 after optimizing their promotional email for mobile users [40] .
Finally, test your email’s performance to confirm it loads quickly and delivers a seamless user experience. Mobile-friendly emails not only enhance engagement but also improve ROI [42] , making this step a must for any successful campaign.
Once your email is optimized for mobile, you’re ready to fine-tune the visual branding details.
Step 8: Review Images and Branding
Visuals are often the first thing people notice in your emails, and nearly two-thirds of recipients prefer emails that are visually appealing [44] . Consistent, polished visuals not only strengthen your brand identity but can also lead to a 13% increase in open rates and boost information retention by 400% [48] . Clearly, this step matters.
Start by testing your images across different email platforms like Gmail, Outlook, and Apple Mail. What looks flawless in one client might appear distorted in another, so always send a test email to yourself and your team. Be sure to check both desktop and mobile versions to catch potential display issues [47] .
When it comes to image quality, aim for a balance between sharp visuals and quick loading times. Use high-resolution images that appear crisp and professional, but keep individual file sizes under 100KB for faster load speeds [44] . In total, the combined weight of all images in your email should stay under 800KB to avoid frustrating recipients, especially those on mobile networks [50] .
Choose the right file format for each type of image:
JPEG for detailed photos
PNG for logos or graphics with transparency
GIF for animations [44]
"Accessibility is an investment in your ability to retain future subscribers at a higher rate." - Chad S. White, Head of Research at Oracle Digital Experience Agency [46]
Accessibility is just as important as aesthetics. Add descriptive alt text to every image so your message remains clear even if the visuals fail to load [44] .
Consistent branding plays a big role in building trust and recognition. Companies with cohesive branding are valued up to 20% higher [52] , and 90% of customers expect a seamless experience across all marketing platforms [53] . Stick to your established color palette, fonts, and logo placement throughout the email.
Here’s a quick reference for ideal image dimensions:
Image Type | Width (Pixels) | Height (Pixels) |
|---|---|---|
Full Width Banner | 600–650 | 200–400 |
Hero Image | 600–650 | 200–400 |
Logo | 100 | 100 |
Icons | 50–100 | 50–100 |
Single Column Images | 300–600 | Adjust proportionally |
Email Signature Image | Less than 300 | 70–100 |
Responsive design is a must. Use percentage-based widths (e.g., width: 100% within a container) instead of fixed dimensions to ensure your images scale properly on all devices [45] . Stick to aspect ratios like 16:9 or 4:3 to avoid distortion [44] . Keep in mind that mobile devices account for 26% to 78% of email opens [49] .
Don’t forget to set fallback colors for background images. This ensures your text remains legible even if the images fail to load [47] .
Some recent campaigns showcase these principles in action. For example, in 2025, Brooks used regional weather data to display personalized hero images for different geographical segments [45] . Adidas took personalization further by using demographic data to show gender-specific visuals in their emails [45] .
To further optimize your images, use tools like TinyPNG or Compressor.io [47] . Experiment with compression levels to strike the right balance between visual quality and fast loading times. Stick to a resolution of 72 ppi to keep file sizes manageable [50] .
Lastly, pay special attention to your email header. Including a logo in the inbox can increase open rates by 21% and boost purchase likelihood by 34% [51] . Ensure your logo appears clearly and that your brand colors align with the rest of your marketing materials.
With your visuals polished and branding consistent, you’re ready to move on to reviewing legal compliance - one of the final steps before launching your campaign.
Step 9: Confirm U.S. Legal Compliance
Email compliance isn't just a formality - it can save you from hefty fines. Under the CAN-SPAM Act, each violation could cost you up to $53,088 per email [54] . That’s why ensuring every email you send follows federal guidelines is non-negotiable.
"Despite its name, the CAN-SPAM Act doesn't apply just to bulk email. It covers all commercial messages...including email that promotes content on commercial websites. The law makes no exception for business-to-business email." - Federal Trade Commission [54]
Start by double-checking your email headers. Make sure the "From", "To", "Reply-To", and routing details correctly represent your business [54] . Misleading information here can land you in trouble.
Your subject line should clearly and honestly reflect the email's content. Additionally, every email must prominently display your physical postal address. This can be your current street address, a USPS-registered P.O. box, or even a private mailbox registered with a commercial mail receiving agency. Most businesses include this information in the footer, alongside other contact details [54] .
Next, test your unsubscribe link. Send yourself a test email and go through the opt-out process. The law requires that unsubscribing be simple - no logins, no hoops to jump through. It should work by either clicking a single link or replying to the email [54] [57] .
"Your message must include a clear and conspicuous explanation of how the recipient can opt out of getting marketing email from you in the future. Craft the notice in a way that's easy for an ordinary person to recognize, read, and understand." - Federal Trade Commission [54]
As of February 2024, bulk senders must meet updated standards introduced by Google and Yahoo - now adopted by providers like Outlook. These rules require one-click unsubscribe links in both the email body and header [55] . Make sure your unsubscribe process takes no more than two clicks.
Federal law allows up to 10 business days to process unsubscribe requests, but best practice (and some providers’ requirements) is to handle them within two days. Also, the opt-out mechanism must remain active for at least 30 days after the email is sent [54] [55] [56] [58] .
Don’t forget to mark your commercial emails as advertisements, and ensure any third-party email providers you work with follow these same standards [54] .
Before hitting send, run through this checklist one last time:
Is your physical address displayed correctly?
Does your unsubscribe link work as it should?
Are your header details accurate and transparent?
Taking these steps not only keeps you compliant but also protects your reputation as a sender. A little extra diligence now can save you thousands in fines and build trust with your audience. Once you’ve confirmed everything, you’re ready to move on to the final pre-send checks.
Step 10: Choose Send Time and Frequency
Timing can make or break your email campaign. Even the most compelling content can get lost if sent at the wrong moment.
Research suggests that mid-week days - like Tuesday, Wednesday, and Thursday - often perform better than Monday or Friday across many industries [59] . HubSpot's data highlights that emails sent on Tuesdays tend to have higher open rates, with 11:00 AM EST frequently hitting the sweet spot for engagement [60] . But here's the catch: your audience's habits may not align with these general trends.
For instance, retail shoppers and business professionals have very different email-checking patterns. While business users are more active during standard working hours, consumer-focused audiences often engage during lunch breaks or in the evening. Campaigns for causes or nonprofits might see better results in the evenings or over the weekend [59] .
Time zones also play a big role. For example, sending an email at 9:00 AM on the East Coast means it lands in West Coast inboxes at 6:00 AM. Segmenting your list by time zone can help ensure your emails arrive at the right moment for each recipient. And here's a pro tip: avoid sending emails exactly on the hour. Instead of scheduling for 11:00 AM, try 10:55 AM to stand out from the flood of messages hitting inboxes at predictable times [60] .
Email frequency matters just as much as timing. Send too many emails, and you risk overwhelming your audience. Send too few, and they might forget about you entirely. On average, remote workers receive 171 emails per week [61] . Many businesses find that two to three emails per week strike the right balance for engagement, though some industries - like clothing retailers - send as many as 6.21 emails per week [62] . Keep a close watch on your unsubscribe rates, as about 73% of people cite receiving too many emails as their top reason for opting out [62] .
To fine-tune your strategy, build on your segmentation and testing efforts. Start with a control send time, like Tuesday at 11:00 AM, and experiment with different days and times. Track key metrics such as open rates, clicks, conversions, and unsubscribes to see what resonates with your audience.
Different types of emails also call for different approaches. Automated emails - like welcome sequences or abandoned cart reminders - should be triggered by user actions, not a fixed schedule. Meanwhile, promotional emails and newsletters benefit from consistent timing, which helps set expectations for your subscribers.
Consistency is key. Nearly a quarter (23%) of email opens happen within the first hour [63] . Be mindful of seasonal shifts and events that might affect inbox habits, and remember that timing is never a "set it and forget it" strategy. Regular testing and adjustments ensure your emails land when your audience is most likely to engage.
Step 11: Set Up Tracking and Analytics
Understanding how your emails perform comes only after they're sent. Without proper tracking, you’ll miss key insights - like which links drive traffic, which content leads to conversions, or how much revenue your emails bring in.
Adding UTM Parameters
UTM parameters are small code snippets you tack onto the end of URLs to track website traffic [65] . They help you follow a subscriber’s journey from the email they opened to the action they took.
For effective tracking, focus on three key UTM parameters: medium, source, and campaign [65] .
Here’s a real-world example: Email on Acid used UTM parameters to track their campaign for a new spell check tool. Their setup included:
Campaign source:
hs_email(HubSpot)Campaign medium:
emailCampaign name:
Spell Check
A link in their email looked like this:https://www.emailonacid.com/blog/article/eoa-news/email-spell-check-spell-check-emails-before-sending-with-email-onacid/?utm_campaign=Spell%20Check&utm_source=hs_email&utm_medium=email [66] .
UTM Best Practices
To keep things organized and accurate:
Stick to a clear naming convention that your team can consistently follow [64] . Use lowercase, descriptive tags, replacing spaces with dashes (e.g., "product-launch-announcement" instead of "email1").
Apply UTM tags only to external links leading to your website [64] . Avoid tagging internal links, as it can distort your analytics data.
Key Metrics to Monitor
Your tracking setup should capture both engagement and conversions [68] . Here are the essentials:
Open Rates: Gauge how well your subject lines perform. A good range is between 17% and 28%, with the average at 21.5% in 2021 [69] .
Click-Through Rates (CTR): This measures direct interaction with your email content. Average CTRs hover around 2.3%, with a range of 2% to 5% considered solid [69] .
Click-to-Open Rate (CTOR): CTOR shows how compelling your content is to those who opened the email. A healthy CTOR falls between 6% and 17%, with an average of 10.5% in 2021 [69] .
Conversion Rate: Tracks the percentage of recipients who complete your desired action, like making a purchase, signing up for a webinar, or downloading a resource [68] .
On average, email campaigns generate $36 for every $1 spent [70] . Tracking revenue per email is crucial to understanding your return on investment.
Configuring Analytics Tools
To track performance effectively, connect your email platform to Google Analytics. Add a tracking pixel to the bottom of your email to minimize load times [71] . Then, send test emails to ensure Google Analytics correctly captures open events [71] .
For clicks, use a URL builder to create links with UTM parameters, and insert these into your email content [71] . Monitor real-time reports in Google Analytics to confirm that clicks are being tracked accurately [71] .
Custom dashboards are a great way to consolidate all your key metrics in one place. This makes it easier to identify trends and evaluate the success of your campaigns at a glance [72] .
Keeping Data Clean
Ensure your data remains reliable by validating new sign-ups and managing bounces [73] . The average unsubscribe rate for e-commerce emails is just 0.19% [70] . If your rate is much higher, your analytics can help pinpoint whether content or frequency is the culprit.
Document your tracking setup, train your team, and regularly review performance data [72] . Real-time analytics let you monitor campaigns as they happen, allowing for quick tweaks - especially useful for time-sensitive promotions or when experimenting with new strategies.
Step 12: Send a Final Test Email
Before hitting "send" on your campaign, take one last critical step: send a final test email. Think of this as your ultimate defense against errors - a chance to ensure everything is polished and ready for your audience.
This isn't just another routine check. It's about experiencing the email exactly as your subscribers will, catching anything that might have slipped through earlier rounds of review.
Creating Your Test Group
Now that you've handled technical and content checks, it's time to verify the entire user experience. Send the test email to a mix of people: yourself, your team, and a few trusted contacts outside your organization. Make sure this group includes users of different email clients (like Gmail, Outlook, Apple Mail, and Yahoo) and devices (desktop and mobile). This variety helps uncover issues that may only appear in certain environments.
The Complete Review Process
When the test email hits your inbox, review every detail:
Check that it lands in the inbox, not the spam folder.
Confirm the subject line, sender name, and preheader text display as intended.
Verify personalization fields populate correctly - look out for errors like "Hello [FIRST_NAME]."
Ensure the formatting looks right on both desktop and mobile devices.
Technical Validation
Now, dive into the technical side. Test every link in the email, including navigation links, call-to-action buttons, social media icons, and embedded URLs. Make sure they direct to the correct pages and that those pages load without issues.
Also, check that images appear at the correct size and resolution. Don’t forget to verify that alt text is visible when images are disabled.
"Slow down and double check, before you move on. Then… check again." – Carin Slater, Litmus' Email Marketing Specialist [74]
Common Issues to Watch For
During this stage, keep an eye out for these frequent problems:
Broken links caused by typos or incorrect formatting.
Image errors, such as files that fail to load or appear distorted.
Mobile rendering issues, where text might be too small or buttons hard to tap.
Compliance and Accessibility Check
Revisit compliance details like the unsubscribe link and physical address to ensure they're present and functional. For accessibility, review color contrast, font readability, and alt text for images to make sure your email is inclusive for all subscribers.
Final Spam Filter Test
Once you're confident in the design and functionality, run a spam filter test. This helps identify any red flags - like overly promotional language, an imbalance of text and images, or authentication issues - that could harm deliverability. Fix any issues that could trigger spam filters before moving forward.
Documentation and Team Review
Share the test email with your team and document any problems you find. This final review brings together all aspects - content, design, compliance, and technical performance - to ensure your campaign meets your standards. A simple checklist of what’s been reviewed and fixed can help you stay organized and serve as a reference for future campaigns. Having more than one person review the email increases the chances of catching errors.
After addressing all issues, send one last test email to confirm everything is perfect. Once it passes this final check, you’re ready to launch your campaign with confidence.

FAQs
What steps should I take to ensure my email campaign meets legal requirements in the US?
To keep your email campaigns on the right side of US laws and avoid hefty fines, make sure to follow these essential steps:
Obtain clear consent from recipients before sending any emails.
Provide a visible and simple way to unsubscribe, allowing recipients to opt out anytime.
Clearly state your business identity, including a valid physical mailing address in your emails.
Stay compliant with the CAN-SPAM Act, which sets specific rules for commercial emails and enforces penalties of up to $53,088 per violation.
These practices not only help you avoid legal trouble but also strengthen trust with your audience.
How can I optimize email campaigns for mobile devices to boost engagement?
To make your email campaigns more effective on mobile devices, concentrate on responsive design. This ensures your emails automatically adapt to various screen sizes. A clean, single-column layout paired with short, clear text improves readability on smaller screens.
Incorporate large, tappable buttons (at least 44px in height) for calls-to-action, making it easy for users to interact. Steer clear of tiny fonts and cluttered layouts that can frustrate readers. Always perform mobile testing to confirm that links, images, and formatting appear correctly on different devices. These adjustments can create a smoother experience for mobile users, boosting both engagement and click-through rates.
What’s the best way to use A/B testing to boost open and click-through rates in my email campaigns?
To get the most out of A/B testing in your email campaigns, start by focusing on a single element to test. This could be the subject line, call-to-action (CTA), or even the email design. Testing just one variable at a time helps you pinpoint exactly what drives better results.
Divide your email list into two random groups and send each group a different version of your email. Make sure your sample size is large enough to yield reliable insights. It's a good idea to test emails with strong engagement potential, like newsletters or promotional offers. Once the test starts, resist the urge to tweak anything midway - let it run its course.
When the test wraps up, dive into the results to see which version performed better. Use these findings to refine your future campaigns and keep improving your open and click-through rates.
