Another user was really accurate with these 3 points:
1. Minimize to System Tray – Add a setting to minimize the app to the system tray instead of the taskbar/dock when closing or clicking the minimize button.

2. Launch on Startup – An option to automatically launch the app when the system boots.

3. Start Minimized to Tray – A companion option to launch the app directly into the system tray (useful for keeping the app running discreetly).

These are critical for the usability in any desktop system

It feels crazy that this would ever even need to be a request. This is such an essential and basic feature for a mail service desktop client. Why even release the client without it at all?

This is the type of basic but severe friction that makes it impossible to recommend Proton to friends and family — there's so much that simply should work but doesn't. It's not AI features, it's not highly complex issues — it's basic usability such as minimizing to taskbar, mail content search (takes a while but we get some of them), properly functioning composer, etc.

For people that don't care too much about privacy due to being uninformed, or those that don't understand tech too well — oftentimes the issue is not that the service is paid, it is simply that the service doesn't do the basic stuff a generic user needs it to do.

L'app Windows manque tellement de fonctionnalités essentielles qu'elle est parfaitement inutile...

This is an essential feature and one of the most basic for an email app that has to be up constantly in order for its users to be notified of new emails on time. Come on guys....

Closing the protonmail linux application should'nt close it totally. It should rather minimize it in the systray, ready to notify if any mail is received. The systray icon could even change depending if there is or there is not new mails or calendar entries...
The ProtonVPN linux application has already this behaviour.

Actually, if you close the app, you won't receive any notification about new mails, or entries in calendar...

For me, having the app go to the system tray, and auto-start on windows startup are essential. If this does not happen, I might as well just open a tab in my browser, because I have already bookmarked it.

Please add this features plus an envelope notification in tray.

Why even make a desktop client if it can't auto start with windows and minimize to tray...? Why does proton ship products missing basic functions and when community brings it up they don't implement them for 5 years?

This is the only reason I haven't switched to the Windows client. Just installed it and couldn't believe that it just closes completely. Guess I'll keep using Thunderbird with Bridge until this becomes a feature.

Why is this taking so long to implement?

I’d like to suggest a few usability improvements for the Proton Mail Desktop App:

1. Minimize to System Tray – Add a setting to minimize the app to the system tray instead of the taskbar/dock when closing or clicking the minimize button.

2. Launch on Startup – An option to automatically launch the app when the system boots.

3. Start Minimized to Tray – A companion option to launch the app directly into the system tray (useful for keeping the app running discreetly).

These features would align the app with common expectations for desktop email clients and improve workflow efficiency. Thanks for considering them!

Please, god. Please do this.

Also there should be an option for starting the app in the tray so it can be loaded at startup without the window opening everyime.

Please fix this!

I think its a shame the mail client has no systray icon feature yet, I use dwm and cannot minimize the app to anywhere else.

The fact that this still hasn't been dealt with tells us all that we need to know...

Would be great to have a minimized startup option with the desktop mail app in the system tray.

This is utterly ridiculous. Here to voice my displeasure that this is STILL not working after all of this time.

Tuta is light years ahead of Proton

It looks like this request is falling on deaf ears.

My renewal comes up in a couple of months and I am forced to rethink paying for premium email without premium features. Please implement this feature !

It should be a priority to implement minimize to taskbar with a badge count. Windows does give notifications as long as the app is open but that just isn't good enough. Act like you care about your app.
