Proton Mail v3.3 Release Notes

Share this page

We have added two major enhancements to Proton Mail’s secure email service: Desktop Notifications and Hotkeys/Keyboard shortcuts

One of the goals of Proton Mail is to make encrypted email easy-to-use.  This is why Proton Mail version 3.3 puts a heavy emphasis on the usability of Proton Mail by adding these two highly requested features. Below, we discuss these two enhancements to your secure inbox and how to make best use of them.

Proton Mail doesn’t abuse your privacy or sell ads. We rely entirely on revenue from Proton Mail Plus accounts to fund continued development. Please consider upgrading to support the project and protect online privacy.

Desktop Notifications

Waiting for an important email to arrive? Now with Desktop Notifications you do not have to continuously monitor your Proton Mail account in anticipation of the email’s arrival. Once Desktop Notifications has been allowed you will receive a popup notifying you of new messages, no matter what you are doing on your computer. Learn more about how to setup Desktop Notifications.

Hotkeys/Keyboard Shortcuts

Bouncing back and forth from your keyboard to your mouse can be time consuming as we try to read and respond to emails in our inbox. Keyboard shortcuts (also known as hotkeys) allows you to easily move around your inbox using the keys on your keyboard to perform the task you usually perform with the mouse. It is possible to view all the keyboard shortcuts Proton Mail supports by typing the question mark ? anywhere in your inbox. Learn more about how to use Proton Mail Keyboard Shortcuts.

If you have any additional suggestions for existing or new keyboard shortcuts, feel free to let us know in the comments below.
