Last March, ProtonMail launched out of beta. This March, we’re bringing back ProtonMail Beta so you can test new ProtonMail features before they are released.

Today, we’re announcing the immediate availability of a new site, beta.protonmail.com where we will be hosting experimental releases of ProtonMail. As many of you probably recall, ProtonMail spent over two years in beta before it was finally released to the world in March 2016. During our original beta, we worked closely with our user community to refine and develop ProtonMail into the world’s best secure email service.

As a community driven project, ProtonMail’s development path has always been driven by the user community, and the beta site will serve as a way for interested members of the ProtonMail community to provide feedback on new features prior to public release. Anybody can access the ProtonMail beta site, and beta.protonmail.com will qualify for our security bug bounty program.

Note, there is also an existing ProtonMail Mobile Beta Program, which will continue to be actively maintained and supported by the ProtonMail Team.

Release Notes and Feedback

At the bottom of this post, we will be publishing up to date release notes for the ProtonMail beta releases.

Reporting Bugs

Note, beta.protonmail.com will be hosting experimental builds, which are more likely to have bugs, as beta builds generally undergo less strenuous testing. If you find a bug in ProtonMail Beta, please let us know using the report bug feature built into ProtonMail:

Theme Developers

For the ProtonMail custom theme developer community, beta.protonmail.com will serve as a tool to test your theme on new ProtonMail builds before they go public, so your custom theme can be tweaked to account for any new features or CSS changes. We will also try our best to detail any new CSS changes in beta builds of ProtonMail in the release notes below.
