Email Signature Accessibility Guide

Accessible signatures improve communication for everyone. Small design choices – like useful alt text and readable contrast – make a measurable difference for recipients using assistive technology.

Accessibility principles for signatures

• Meaningful alt text: describe purpose, not decoration.
• Readable hierarchy: keep layout simple and predictable.
• Color contrast: ensure text remains readable against backgrounds.
• Link clarity: use descriptive link labels instead of vague text.

Alt text examples

• Weak: logo
• Better: Mirosign company logo
• Best: Mirosign logo linking to company website

Screen-reader-friendly layout tips

• Limit visual clutter and nested elements.
• Keep contact details in a clear logical order.
• Avoid using images for essential text content.
