Note: If Proton Mail Mobile version 1.6 causes your iOS or Android app to show all messages as encrypted text, logging out and logging back into the mobile app will fix the problem.

It is still possible to register for the Proton Mail Mobile Beta Program. Not only is this a great way to support Proton Mail, you will be able to get early access to the newest mobile features before they are publicly available.

Proton Mail v1.6.0 contains numerous bug fixes and improvements to Proton Mail mobile to improve your email privacy and user experience. The biggest change is the addition of custom folders support!

Please consider supporting Proton Mail by upgrading to a paid plan(new window). Your support allows us to continue to develop Proton Mail encrypted email as free and open source software(new window).

Custom Folders
(new window)

android and ios folders(new window)

Folders provide the ability to store messages in different locations within your account. In the past, Proton Mail has had 5 fixed folders: Inbox, Sent, Archive, Trash, and Spam. All the messages within your inbox was saved in one of these 5 folders. In addition to these 5 folders, we provided labels to organize the mail within the folder the message was stored in. With the introduction of custom folders, you can now create as many folders as you need and store messages within those custom folders. Learn how to create and use folders.
