Question 1

Why does email accessibility matter for deliverability?

Accepted Answer

Accessible emails reach more subscribers and avoid spam flags. Screen reader users who cannot interact with your email may mark it as spam, hurting your sender reputation. WCAG-compliant emails also typically score higher on inbox placement algorithms used by Gmail and Outlook.

Question 2

What is WCAG and why does it apply to emails?

Accepted Answer

WCAG (Web Content Accessibility Guidelines) defines standards for text contrast, image alt attributes, link descriptions, and reading order. While not legally required for emails in all regions, WCAG compliance is increasingly required in regulated industries and improves engagement from the 1.3 billion people globally with disabilities.

Question 3

What does the Aria Accessibility Audit check?

Accepted Answer

Aria checks: color contrast ratios against WCAG AA and AAA thresholds, missing or empty alt attributes on all images, ambiguous link text (e.g. click here), logical reading order for screen readers, table role attributes, and proper use of heading hierarchy.

Question 4

How do I fix low color contrast in emails?

Accepted Answer

Use the RenderOps Contrast Checker tool to test specific color pairs. For body text, you need a minimum 4.5:1 contrast ratio (WCAG AA). For large text (18px+ or 14px+ bold), a 3:1 ratio is acceptable. Avoid light grey text on white backgrounds, which is one of the most common email accessibility failures.
