Make every email accessible: A practical guide to ADA, WCAG, and Section 508 compliance for email signatures
Email signatures are part of every business communication. Without centralized control, they can quietly fail accessibility standards at scale.
WCAG 2.1, ADA Title III, and Section 508 apply to digital communications, including email. When signatures are managed manually or left to individual users, logos render as filenames to screen readers, banners go unannounced, and key information disappears entirely. For organizations with compliance obligations, that creates real legal and reputational risk.
Exclaimer gives IT and brand teams centralized control over the elements that determine accessibility across every signature, including alt text, font choices, color contrast, padding, and layout. Changes made centrally cascade automatically across all linked signatures, so compliance does not depend on individual users getting it right.
