FMail2
The Mac application for Fastmail users
Why?
Email provider Fastmail has native iOS and Android clients. But nothing for macOS. The web interface used by Fastmail is excellent.
The big thing missing is that the web interface cannot behave like a native mail application. It can, for example, not handle email links. When you click on such a link it is the macOS Mail application that opens. That is not what we want.

Enter FMail2

- Multiple window support
- Default email client
- Running in the background
- Auto hide
- Tabs
- Dock item with badge
- Swipe support
- Secure
- Notifications
- Status bar menu
- Keyboard shortcuts
- Lightweight
When you have installed FMail2 and have adjusted your default email client, a click on an email link will open FMail2.
Even if you have closed all FMail2 windows (or tabs), you will receive notifications for new email and the Dock icon count will be updated, something that’s not possible when you use Fastmail in a browser. The program can run in the background with only a Status Bar menu for quick access.
There are more options not available in Fastmail, such as searching inside an email and quoting the selected text only. Downloading is handled inside the application and the files are saved in your Download folder (or to another folder of your choice).
Use a separate window for composing or keep the Contacts available in another tab.
If you use Fastmail in your browser, switch to FMail2 now. For free. Guaranteed no tracking of your data. You won’t regret.
FMail2 is an all Swift Mac application, taking little resources on your system and runs natively on Apple Silicon. Checking email is independent of the view chosen, as FMail2 uses JMAP to update this kind of information.
FMail2 runs on macOS 12.0 and later.
Runs natively on Apple Silicon, is notarized by Apple and sandboxed
