Email Accessibility: Meeting WCAG Standards in Your Campaigns

Email accessibility ensures people with disabilities can perceive, understand, navigate, and interact with your email content. With 15% of the global population living with some form of disability, inaccessible email excludes a significant audience. Accessibility is becoming a legal requirement as courts apply WCAG standards to email communications.

The foundation of email accessibility is semantic HTML structure. Use proper heading hierarchy in correct order. Screen reader users navigate by jumping between headings, and logical structure ensures they can understand your content. Use lists for grouped items, tables only for tabular data, and landmark regions where supported.

Color and contrast are critical. Text must maintain a minimum contrast ratio of 4.5:1 against its background for body text. Never use color as the sole means of conveying information. Test color combinations with accessibility tools before every campaign and include high-contrast mode options.

Alt text on images is not optional. Every image needs descriptive alt text conveying the information it communicates. Decorative images need empty alt text so screen readers skip them. Functional images like buttons need alt text describing the action. This is the single most impactful accessibility improvement.

Testing requires both automated and manual methods. Use tools like axe or WAVE to catch common issues. Then test with a screen reader like VoiceOver on iOS or NVDA on Windows. Navigate using only keyboard. Read through your email with images disabled. Each test reveals issues automated tools miss.
