What is accessibility in email design?

Accessible email design applies inclusive design principles to email creation-ensuring visual, structural, and content elements work for users with varying abilities. It covers everything from color choices to HTML structure to copy clarity.

Design considerations: Visual-color contrast, font size, color-independent meaning. Structural-semantic HTML, logical reading order, proper heading hierarchy. Interactive-large tap targets, clear focus states, descriptive link text. Content-plain language, alt text, avoiding jargon. Media-no flashing animations, controlled motion.

Accessibility is a design constraint that improves outcomes. Like responsive design or mobile-first thinking, accessibility forces clarity and intentionality. The email that works for a screen reader user also works better for someone reading quickly on their phone.
