Great design isn’t just about style—it’s about making sure everyone can access your message. Whether your audience includes people with visual impairments, cognitive disabilities, or motor challenges, accessibility in email design ensures no one is left out of the conversation.

Accessible emails aren’t just about ticking compliance boxes. They’re about inclusion, brand integrity, and creating digital experiences that feel effortless for everyone. The best part? What’s good for accessibility often improves performance for all users.

In this guide, we’ll explore what accessibility means in email, why it matters, and how you can implement it without compromising creativity.

What Is Email Accessibility?

Email accessibility is the practice of designing and writing emails so they can be understood and navigated by people with a variety of physical, cognitive, and sensory impairments.

That includes:

• People using screen readers
• Users who navigate with keyboards
• Readers with visual challenges (e.g. colour blindness, low vision)
• Individuals with dyslexia, ADHD, or other cognitive differences

Creating accessible email layouts ensures that everyone—regardless of ability—can read, navigate, and interact with your content. It’s about respect, reach, and relevance.

Accessibility is often guided by WCAG (Web Content Accessibility Guidelines), which provide a framework for inclusive digital design. But accessibility isn’t just a legal or technical obligation—it’s a human one.

Why Accessible Emails Drive Better Results

Making your emails inclusive has a tangible impact on campaign performance. Here’s why brands benefit when accessibility is baked into their strategy:

Broader Audience Reach

Around 1 in 5 people in the UK have a disability. By creating accessible email layouts, you automatically increase the number of people who can engage with your content.

Improved Readability for Everyone

Simple layout, clear headings, and well-structured copy make emails easier to digest—for all readers, not just those with accessibility needs.

Better Mobile Performance

Accessible design naturally supports responsive design. When you build for clarity and ease, your emails tend to look better across devices.

Stronger Brand Trust

When subscribers find your emails easy to read and navigate, they associate your brand with care, clarity, and professionalism.

At Invoke Media, we build accessibility into our email and automation workflows—so inclusivity becomes part of your performance strategy.

Common Accessibility Barriers in Email

Many emails unintentionally exclude readers through poor design or formatting. Some of the most common issues include:

• Low contrast between text and background
• Missing alt text for images, which leaves screen reader users with no context
• Complex or non-semantic HTML layouts, which confuse assistive tech
• Small or hard-to-read fonts
• Links that say “click here” instead of describing their purpose
• No support for keyboard navigation or screen reader hierarchy

By identifying and correcting these issues, you ensure your messages are readable, actionable, and inclusive.

Best Practices for Creating Accessible Email Layouts

Designing accessible emails starts with a few key principles. You don’t need to overhaul your entire design system—just make thoughtful changes that improve usability.

Use a Mobile-Friendly, Semantic Structure

Use headings (h1, h2, etc.) in a logical order, with clear visual hierarchy. This supports both screen readers and visual skimmers.

Prioritise Contrast

Text should have strong contrast with its background. Dark grey on white, black on pale yellow, or white on navy are more accessible than pastel tones on light backgrounds.

Use Alt Text for All Images

Every image should include descriptive alt text so that screen reader users understand what the image conveys. For decorative images, use empty alt attributes to skip them.

Keep Fonts Clear and Legible

Use a minimum font size of 14px, avoid condensed typefaces, and steer clear of low-contrast colour pairings.

Avoid Relying on Colour Alone

Use bold text, underlines, or icons alongside colour cues to indicate meaning. For example, don’t just make important text red—add context like “Important: deadline approaching”.

Design With Tappable Targets

Buttons and links should be large enough to tap on mobile and should have clear, descriptive labels.

Our branding and design service includes accessibility as part of every visual asset we create, so your emails remain functional and stylish.

Writing Copy for Accessible Emails

It’s not just about layout—your words matter too. Writing clear, well-structured copy is a cornerstone of accessibility.

Use Plain Language

Avoid jargon, overly complex sentences, or idioms that may not be universally understood.

Write Logical, Skimmable Sections

Break up copy with headings and bullet points. Readers should be able to scan quickly and understand the message structure.

Use Descriptive Link Text

Avoid vague CTAs like “click here” or “learn more.” Instead, use:

• “Download the brand guide”
• “Read the full case study”
• “Book your free consultation”

Optimise Subject Lines and Preview Text

Make sure the subject line clearly reflects the email’s content. Preview text should expand on it with context—not repeat it.

These writing principles are baked into every project we deliver under our content creation service, ensuring clarity from subject line to CTA.

Testing Your Email for Accessibility

Even the best-designed emails can fall short if they aren’t tested properly. Here’s how to check your work:

Use Accessibility Testing Tools

• WAVE by WebAIM: Check colour contrast, alt text, and structure
• Litmus or Email on Acid: Preview how emails appear across devices and clients
• VoiceOver or NVDA: Test with screen readers to see how your content is interpreted

Manual Checks

• Use tab navigation to test keyboard accessibility
• Read alt text aloud to ensure it adds value
• Resize text and zoom in to check readability

At Invoke, accessibility testing is part of our internal QA process for every client campaign—especially in automated journeys.
