Proton Mail is the inbox people pick when privacy is the point: end-to-end encrypted mail from a Swiss provider, built so that the contents of your messages stay yours. Most of the time you reach it through proton.me in a browser, which works but leaves your private inbox as one more tab among many. Franz loads the Proton Mail web experience as a dedicated desktop service, so the mailbox you chose for privacy gets a fixed, signed-in spot in the sidebar rather than living in a browser window you keep losing.
A private inbox that stays its own
Running Proton Mail as its own Franz service means it has an isolated session, separate from your other mail and your work chat, which suits an inbox you keep deliberately apart. If you run more than one Proton account, a personal address and a separate one for sensitive correspondence, you can add the service again and keep both signed in at once, each in its own tab with its own unread count. You compose, encrypt, and organize exactly as you do on the web, because it is the same Proton Mail client, just wrapped as a focused desktop window. Proton's encryption model is unchanged; Franz simply gives that web client a steady home.
New mail without watching a tab
Franz delivers native desktop notifications for Proton Mail, so a new message reaches you the moment it arrives instead of waiting silently in a browser you forgot to leave open. The unread badge on the tab keeps a count at a glance, and because the inbox runs as its own service, it keeps alerting you while you work elsewhere. You stay reachable on a private address without parking a browser window open all day just to catch what comes in.
Proton Mail on every desktop OS
Franz is a native desktop app for macOS, Windows, and Linux, and Proton Mail behaves the same on all three, with a real dock or taskbar badge and consistent notifications regardless of platform. Whether you are on a Linux laptop or a Mac, your Proton Mail setup feels identical everywhere instead of being relearned per machine. It is a straightforward way to give a privacy-first mailbox a proper place on the desktop, right next to the rest of how you work.
