Email remains one of our most important communication tools. With over 4.26 billion email users worldwide in 2022 and an expected growth to 4.73 billion by 2026, email's reach is undeniable. Yet, a shocking 99.97% of emails tested have serious accessibility issues that affect people with disabilities.When we create emails that everyone can access, we open our messages to a wider audience. This includes the 1.3 billion people worldwide living with disabilities. Making your emails accessible isn't just kind—it's smart business.
What Are Email Accessibility Standards?
Email accessibility standards are guidelines that help create emails everyone can read, understand, and interact with. These standards ensure your messages work for people with visual, physical, cognitive, and neurological disabilities.The main standard for email accessibility is the Web Content Accessibility Guidelines (WCAG). These internationally recognized guidelines outline how to make digital content accessible to people with disabilities.WCAG standards follow four main principles, often called POUR:
Perceivable: Information should be presented in ways people can access through one of their senses
Operable: Users must be able to interact with all elements of your email
Understandable: Your content should be clear and easy to understand
Strong: Your emails must work well with assistive technologies
There are three levels of WCAG conformance:
Level A (minimum accessibility)
Level AA (mid-range, what most organizations aim for)
Level AAA (highest level of accessibility)
Why Email Accessibility Matters
Reaching a Wider Audience
One in four adults in the United States and European Union have a disability. Globally, that's one in six people. Here's how some common disabilities impact email engagement:
Vision impairments: At least 2.2 billion people globally have vision impairment
Color blindness: Affects 1 in 12 men (8%) and 1 in 200 women (0.5%)
Dyslexia: Impacts 15% of people, making reading difficult
Cognitive disabilities: Affect 13.9% of U.S. adults
Aging population: By 2030, 1.4 billion people will be 60 or older, often experiencing vision and cognitive changes
If your emails aren't accessible, you're missing a huge audience—and potential customers.
Legal Requirements
Accessibility isn't just nice to have—it's often legally required:
The Americans with Disabilities Act (ADA) and UK's Equality Act set foundational accessibility requirements
WCAG and Section 508 provide web accessibility guidelines
The European Accessibility Act (EAA), effective June 2025, expands digital accessibility standards
Business Benefits
Beyond ethics and compliance, accessible emails drive business results:
People with disabilities control over $1 trillion in annual disposable income
Accessible design improves the experience for everyone
Accessible emails boost engagement and subscriber retention
Accessibility enhances your brand reputation
Email Accessibility Best Practices
Visual Design Elements
Use Color Intelligently
Ensure high color contrast between text and background (at least 4.5:1 for standard text)
Don't rely solely on color to convey important information
Use WebAim's Color Contrast Checker to test your color combinations
Choose Accessible Typography
Use larger font sizes (minimum 16px for body text)
Select readable, evenly-spaced fonts
Avoid using all caps, which can be difficult for people with dyslexia
Keep text left-aligned for better readability
Limit the use of italics and bold text
Create a Clear Layout
Use a simple, single-column layout when possible
Include plenty of white space
Avoid justified text, which creates uneven spacing
Break content into short paragraphs with clear headings
Use semantic HTML elements for proper structure
Content Considerations
Write Accessible Copy
Keep language simple (aim for grade 7-8 reading level)
Use clear subheadings to organize content
Avoid jargon and complex terminology
Write descriptive link text instead of "click here"
Set line spacing to about 1.5 times the font size
Handle Images Properly
Always include alt text for images
Make alt text descriptive enough to convey the image's meaning
Maintain an 80:20 text-to-image ratio
Avoid emails that consist only of images
Be Careful with Dynamic Content
Avoid content that flashes at certain rates, which can cause seizures
Limit animated GIFs or provide static alternatives
Ensure videos include captions and transcripts
Technical Considerations
Make Emails Responsive
Design emails that work well on all devices and screen sizes
Test your emails across different email clients
Use responsive design techniques
Create Accessible Links and Buttons
Make buttons large enough (42-72px) for easy clicking
Ensure links are underlined or otherwise distinguishable
Create bulletproof buttons that display even when images are turned off
Support Assistive Technologies
Use proper HTML structure with semantic elements
Test with screen readers
Include proper heading hierarchy (H1, H2, H3)
Ensure keyboard navigation works
Testing Your Email Accessibility
Before sending your emails, test them for accessibility:
Check color contrast with tools like WebAim's Color Contrast Checker
Test with screen readers like NVDA or VoiceOver
Try navigating your email using only a keyboard
View your email with images turned off
Test across multiple devices and email clients
Use Litmus Email Previews to see how your email appears to users with color blindness
Getting Started with Email Accessibility
Improving your email accessibility doesn't have to happen all at once. Start with these steps:
Add alt text to all images
Increase your font size to at least 16px
Check your color contrast
Structure your content with proper headings
Replace "click here" links with descriptive text
Test with a screen reader
