Clean Your List
A visual representation of an email marketing checklist highlighting the importance of cleaning your email list.
A clean list is key to your email marketing success. A tidy list improves deliverability and your sender reputation so your marketing emails land in your subscribers’ inboxes not the spam folder. Cleaning your list regularly means you’re not wasting effort on undeliverable emails and impacting relationships and revenue. Real time verification during data collection can prevent invalid email addresses getting into your list.
A clean list isn’t just about avoiding the spam filters; it’s about building stronger relationships with subscribers who actually want to hear from you. This will improve your delivery rates and engagement metrics. And with tools like Cleanify.io it only takes a few minutes.
Clean your list every 3 months to keep deliverability and sender reputation in check. Verification and updating of email addresses will boost your campaign results. Neglect this and you’ll get high unsubscribes and potentially damage your sender reputation.

Segment Your Audience
Segmentation is the foundation of marketing email success.
Divide your audience by:
location
lifecycle stage
interests
past behaviour
and you’ll be more relevant and personal. And less unsubscribes.
Segment your audience in your email marketing software by geographic location to send offers to specific regions, and track website behaviour to target users who abandoned their cart.
Segment by customer journey stage and you’ll tailor your messaging better. For example new subscribers get welcome emails with introductory offers, long term customers get loyalty rewards. Use past purchase behaviour to recommend products in emails. Psychographic data like customer interests and values will allow you to personalise even deeper and your emails will resonate more with your audience.
Using multiple segmentation strategies will refine your targeting and make your email campaigns more relevant. By filtering on position, lifecycle stage, interest and geo-location you can create highly personalised and effective email campaigns that cater to your subscribers’ preferences.

Clear Goals
Clear goals will focus your efforts and measure email campaign success. Using the S.M.A.R.T framework (Specific, Measurable, Achievable, Relevant, and Timely) will ensure your goals are clear and realistic. Instead of a vague goal like “increase sales” a S.M.A.R.T goal would be “increase online sales by 15% in the next 3 months through targeted email campaigns”.
Linking email marketing goals to your overall business objectives will make your campaigns more effective. Every email should have a purpose and clear success criteria and time bound objectives. Whether you want to increase engagement, drive traffic to a landing page or increase conversions having clear goals will help you stay focused and track your progress.
Compliance and Legal Stuff
Complying with key email marketing laws like CAN-SPAM, GDPR and CASL will keep you compliant and protect your brand. Getting consent properly whether through double optin or unambiguous consent is key to building a clean email list. Providing clear opt out mechanisms like easy unsubscribe links will allow recipients to manage their preferences and reduce complaints.
Sender identification and authentication is another important part of compliance. Using the correct “From” information and implementing SPF, DKIM and DMARC will verify your identity and improve deliverability.
Respecting data privacy and security by publishing your privacy policy and having data security in place is also important. Regular audits and staying up to date with legal changes will ensure your email marketing is compliant.

Subject Line

Subject line is a key factor in email campaign success by affecting open rates. Short and concise subject lines perform better especially on mobile. Avoid all caps and excessive punctuation to not look spammy. Creating a sense of urgency or exclusivity will make recipients open your emails faster and numbers will add clarity and attention.
Questions in your email subject line will intrigue recipients and increase open rates. Personalised subject lines with the recipient’s name will increase engagement. Doing these will lead to better results in your email marketing.

Optimize Preview Text
Preheader appears next to the subject line and adds to the email’s appeal. It provides extra context and is a complement to the subject line to make a more persuasive and engaging introduction.
The ideal length for email preheaders is between 30 to 55 characters. Make sure your preheader mirrors the email content and you’ll see a big increase in engagement and open rates.
Personalise Your Emails
A visual guide to personalizing emails for better engagement in email marketing campaigns.

Including the recipient’s name in your email greeting will make them feel familiar and connected. AI tools can help you craft personalised and effective subject lines and dynamic content that adjusts to recipient data will make each email more relevant.
Adding visuals and personalised messaging to automated emails will increase engagement and brand loyalty.

Content Quality and Relevance
High quality and relevant content will keep your subscribers interested and engaged. Knowing your audience’s preferences, interests and pain points will allow you to tailor your content. Every email should have value, insights, solutions, discounts or exclusive content. Regularly update and refresh your content to stay relevant and keep your audience engaged.
Test different content formats like newsletters, promotional emails and educational content to see what works best for your audience. Don’t over promote by balancing promotional content with informative or entertaining content to keep your subscribers interested. Keep your content short and sweet, use short sentences, break up text with headings, bullet points and visuals to make it readable.
Focus on one message per email to not overwhelm your readers. Use visuals to complement the text and grab attention. Keep your brand voice and consistency to build brand recognition. Personalisation and segmentation will make content more relevant and clear CTAs will make each email have a clear goal.

Mobile Design
As most emails are opened on mobile devices mobile friendly design is a must. Responsive email design will make the layout adapt to different screen sizes. Using simple and flexible email templates, preferably one or two column layouts will make it more readable across devices. High contrast in colour selection is key to readability.
Good email design should be simple and clear, each element should have a clear purpose. A clear content hierarchy, like using bigger headlines and shorter paragraphs will help user navigation.
Compatibility tests should cover multiple devices, mobile, desktop and tablets to have a consistent user experience.
Email Rendering Test
Testing email rendering across different clients and devices will make it look perfect on any platform. Using tools that provide preview across multiple email clients will ensure design consistency. Real time preview will give you immediate feedback on design changes during email development and testing links across multiple email clients will help you identify compatibility issues.
Testing emails will help you identify layout issues before you send, prevent potential problems. Using a sandbox environment will allow you to test without sending emails to actual recipients, so you can keep your privacy during debugging.

Proof and Check Grammar
Proofing will eliminate grammar mistakes and make the email flow naturally. Tools like Grammarly and Hemingway will help you proof and improve content readability. Strategies to proof are taking breaks to get a fresh perspective and reading emails out loud to spot mistakes.
Check for spelling, grammar and punctuation and avoid passive voice and complex vocabulary.
Include a Strong CTA

A strong CTA will prompt the recipient to take action. Make sure your email campaign has only one goal so the CTA is effective. Using action words in your CTA will increase engagement and responses. Adding sense of urgency to your CTA will increase click through rates big time.
Using contrasting colours for CTA buttons will make them pop against the email background. Review graphics and CTAs in the email to make sure they engage the reader and make them scroll.
Placing CTAs at the top of the email will increase visibility and interaction with the email content. Limiting the number of options around your main CTA will prevent distractions and make it more effective.
Test All Links
Testing all email links will prevent subscriber frustration and protect your brand. Broken links will make the recipient unhappy and poor campaign results. Double check CTA links and landing pages to ensure it’s working. Use a URL checker software or manually click each link to test.
Unsubscribe link must work and give the recipient a choice in communication frequency as per CAN-SPAM Act.
A/B Test
A/B testing will optimize your email marketing. By testing different email versions to a small percentage of your audience you can identify which one performs better and get higher open rates and engagement. What to test? Subject line, preview text, CTAs, email layout and other design elements.
The process is to send a test email with different versions to about 20% of your subscribers and then roll out the best performing one to the rest of the audience. This will allow data driven decision that will improve your email campaign performance over time.

Schedule Send Time
Send time matters a lot to engagement rates. Research says the best time to send emails are around 9-11 AM or early afternoons when people are most likely to check their inbox. Tuesdays have better open rates compared to other weekdays.
For global audience, the “following the sun” strategy which is sending emails at local sunrise time can be very effective. Sending emails at odd minutes past the hour can also speed up delivery. By scheduling your emails at optimal time based on subscriber behavior you can increase open rates.
Autoresponders
Autoresponders will maintain engagement and send timely message to the recipient. Email autoresponders will nurture new subscribers and keep warm leads interested. Delaying your first email to a new subscriber will make them forget about your brand.
Setting up autoresponders will ensure that subscribers get instant communication and will be engaged with your content. Email marketing tools can help you create and schedule these replies based on recipient’s action. Autoresponders will maintain ongoing engagement with new subscribers and will keep them interested in your communication.
Email Metrics
Monitoring the metrics will evaluate the performance of your email campaign. Metrics such as open rates, click-through rates, bounce rates and conversions will give you an idea how your email is performing. Monitoring these metrics regularly will keep your sending reputation good.
Click-through rates (CTR) is the percentage of recipients who engaged by clicking the links in the email, conversion rates is the percentage of recipients who took an action after clicking through. Bounce rates is the percentage of emails that didn’t reach the recipient.
By using these metrics you can make data driven decision for future campaign.
Spam Filters
Understanding spam filters will ensure your email reach subscribers inbox. Spam trigger words in your subject line and email content can make your email get blocked or reported as spam. Check your spam score regularly to avoid this issue. Also research on spam words before you write your email subject line and content.
Follow best practices and understand spam regulations will improve your email deliverability big time.
Accessibility
Making your email accessible to all users including those with disabilities is important. Use live text instead of images for critical information to ensure accessibility and readability across all devices. Providing alternative text for images and avoiding auto-playing animation will improve user experience.
Including accurate captions and transcripts for videos and audio in email will enhance accessibility.
Email Design

Reviewing email design thoroughly will impact engagement and brand perception. Feedback from test email will guide you to adjust to improve overall look and feel of your email. Using same template for newsletter and product announcement will give you a cohesive brand experience.
Get a second opinion on your email design to catch the potential issues and ensure consistency. Sales email should have more visuals and call to action than newsletter. Be meticulous with the tiny details will make your email content look more professional and polished.
Test Email
Testing your email will catch errors and verify quality before the main campaign launch. Test email should be sent to colleagues or manager to ensure they get diverse input on the content. When testing, check grammar, spelling, link performance and how the email look on different devices.
In summary, testing your email will make your final output look polished and professional and will engage your recipient. This step is crucial to iron out any last minute issue and make sure everything works as intended.
