Fastmail is now available as a dedicated desktop app for Mac, Windows, and Linux. It’s the same Fastmail you know and love, now with the focus and convenience of a standalone app.
With our desktop app you can:
Launch Fastmail from your dock or taskbar and find it in your platform’s app switcher.
Make Fastmail your default email client, so email links create a new message directly in Fastmail.
Work whenever, wherever, with full offline support, just like our mobile apps. You can always read your mail, manage your calendar, and write replies — your changes sync back seamlessly when you reconnect.
Whether you’re on macOS, Windows, or your favourite Linux distribution, you’ll find the app feels right at home on your platform, with native notifications, menus, and system integrations.
Getting started is simple. Download the app for your platform, sign in with your Fastmail credentials, and you’re ready to go.
