Quick Start Accessibility by Content Type

Emails & Newsletters

Accessible email works best when it is clear and simple. Use live text, descriptive buttons, and a reading order that still works when images are blocked or layouts collapse on mobile.

Quick Focus

Write a clear subject line and useful preheader text that support the message.
Keep layout simple, preferably one column, with real text and descriptive links.
Test with images blocked, keyboard navigation, zoom, and a screen reader in webmail.

Core Guidance

Do This First

Lead with the message. Make the subject line, preheader, and opening heading clearly explain what the email is about and what action is needed.
Build with resilient content. Use live HTML text for the key message, descriptive buttons, and alt text for every meaningful image.
Test fallback states. Check the email with blocked images, dark mode, mobile width, keyboard navigation, and screen reader reading order.

Essential Checks

Content

Use plain language and short paragraphs so readers can skim quickly.
Make every button and link state its destination or action clearly.
Repeat essential text that appears inside hero images as real HTML text.

Layout

Prefer a single-column structure with a logical source order.
Use tables only when email-client support requires them, and keep them simple.
Avoid hover-only interactions or content that depends on animation to make sense.

Testing

Confirm body text reaches 4.5:1 contrast and controls meet 3:1 non-text contrast.
Check that linked images still make sense when images are off.
Review any auto-generated caption or transcript links if video is promoted in the message.

Common Problems to Catch

Sending an image-only flyer as the email body.
Using two or more complex columns that collapse into a confusing mobile order.
Relying on color alone to show urgency, status, or discount information.
Writing vague calls to action such as 'read more' or 'learn more' without context.

Key WCAG 2.1 AA Checkpoints

High-value checkpoints for emails & newsletters work
Success Criterion	What to confirm
SC 1.1.1 Non-text Content	Meaningful images require alt text, and decorative images should use empty alt text.
SC 1.3.1 Info and Relationships	The reading order of the HTML should match the visual order on screen.
SC 1.4.3 Contrast (Minimum)	Email text needs sufficient contrast against the background.
SC 1.4.10 Reflow	Content should still work at small widths and high zoom without horizontal scrolling.
SC 2.4.4 Link Purpose (In Context)	Buttons and links need clear, descriptive labels.
