Email Design Checklist 2

Set up your email for success.

An important foundation to consider when designing your email is the groundwork for its success. You can do this by planning the first elements of your email that readers will see. These are elements like your subject line and preheader text. Make sure to optimize them in such a way that they encourage opens with catchy (and informative) wording.

Email layout

In order to make your email easy to digest, you have to pay special attention to the way you position every element of your email. Ideally, your email should point to the call-to-action. You can easily achieve this by applying the inverted pyramid principle.

Visuals: Use them well.

Visuals are meant to enhance the aesthetic beauty of your email. However, more than that, they also play a role in encouraging your reader to take action. So, choose your visuals strategically.

Optimize your email

For higher conversion rates, ensure that every element of your email is optimized. From the copy to the links, everything should move your reader into taking action.

Information overload? Use a checklist.

A well-designed email should give your reader a pleasurable user experience that will result in them converting into a customer and taking you up on your offer.

Dynamic content

Before you get going, it’s a good best practice to sketch out the layout of your email.

Email layout

Briefly sketch a mockup of your email.

Use a one column layout as it displays better on mobile.

Use vertical layout as opposed to a horizontal one.

Use space to create chunks of content.

Use the inverted pyramid model to guide the reader to a call-to-action.

Create a hierarchy by checking weight and size to the most important elements.

Email width

Adhere to email max widths of 600-640 pixels (recommended).

User experience (UX)

Place content based on engagement.

Ensure your purpose is defined.

Navigate users to the email goal.

Use a table of contents if your email is long.

Scan your sketch for UX flaws.


You are headed into the homestretch! Now let’s play with some shapes and colors.


Choose colors that match your brand color scheme.

Use contrasting colors for your CTAs.

Warm color tones offer a better experience.

Use a balance of text and imagery.

Optimize file size for quick load times.

Use SVG for icons and logos if possible.

Use alt text to add context to images.

Keep images crisp by using image attributes.


Use a static image with a play button.

Use an animated GIF.

Use cinematographs.

Use HTML5 to embed the video.


An alternate option to video.

Only animate what you need to keep file sizes under control.

Keep file sizes under 1MB or smaller if possible.


Follow brand guidelines.

Always spell check and look for typos prior to sending.

Consider how your message will be perceived to avoid issues.

Use bullets to increase readability and scannability.

White space

Add ample white space around elements to encourage click-throughs.

Give CTA text padding standard: 20px.


The finish line is in sight, time to put on the final touches.

Web fonts and fallbacks

Use web fonts whenever possible.

Set web-safe fallbacks for unsupportive email clients.

Mobile optimization

Use a mobile-friendly template.

Use a clear and easy CTA button.

Make sure your images aren’t too small or hard to see.

Increase the size of the body copy if it’s small on desktop emails (16px is a good size for mobile).

Calls to action (CTA)

Copy – be specific and benefit focused.

Size – keep buttons big enough for clickability on mobile.

Design – choose an accent color to stand out, use padding, and size mobile friendly.

Placement – pay attention to the placement to encourage click-throughs.

Language – the button is there for viewers to take action, so an active verb is typically used to help them take the action.


Add UTM tracking as needed.

Check every link to ensure it goes where it should (desktop and mobile).

Style hyperlink tag with active, hover, link, and visited sites.

Keep an eye on dates, email addresses, and telephone numbers that might get turned into links.


Link to social networks as appropriate.

Include any required legal verbiage.

Include support links as appropriate.

Include referral or F2F links as needed.
