Does WCAG apply to emails?
Many WCAG success criteria are directly applicable to email content, and reviewing the guidelines can be helpful when designing your campaigns.
Do emails have to be 508 compliant?
All broadcast emails (i.e., emails sent to large groups of people) -- internal or external -- and their attachments must also be Section 508 compliant.
What is accessible content in email?
Email accessibility means making sure that everyone can receive and understand your message, regardless of any disabilities or assistive devices they may be using. You can think of accessibility in email as an extension of dealing with email clients with poor support.
