Working to improve the accessibility, user experience, performance, consistency, and reliability of email markup

In 2022, we began our Data Collection project with a clear vision for how this data could benefit the ecosystem starting with our annual accessibility reports. Today, we’re excited to announce the next major step in that vision: The Email Markup Database emailmarkup.org/en/blog/2025...

A comprehensive, continuously updated repository of how real-world emails are built. Real usage metrics from real emails covering HTML and CSS features, external assets and more.

Proton Mail (@proton.me) noticed that some of their data on "Can I Email?" was outdated, and took the initiative to update it themselves. As a result, our 2025 Accessibility Report now reflects a much more accurate picture of Proton Mail’s strong accessibility support.

For years, email developers have relied on invisible spacing hacks to influence what appears alongside the subject line in the inbox. But there can be a cleaner, more consistent approach: a simple meta tag.

Respecting user preferences is a basic accessibility principle, but Google's Gmail makes it nearly impossible for developers to do this. Email clients should enable developers to query the user's system or browser-level settings, like reduced motion or color scheme.

Every government email message in our dataset failed to comply with accessibility requirements. This creates significant barriers for users who rely on assistive technologies. Governments have a responsibility to ensure communications, including email, are accessible to as many people as possible.
