Email Accessibility vs MailDev

Both stand on email testing software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Email Accessibility

Free plan Web

Email Accessibility provides email-focused WCAG checks with issue guidance and client compatibility coverage. Its free plan is limited to one audit each month, and API access remains in development.

Visit Email Accessibility

MailDev brings message inspection, rendering previews, and mail management into a development inbox. Its default lack of authentication and unencrypted storage make it unsuitable for public exposure or production traffic.
