Introducing the Fastmail desktop app

Whether you’re on macOS, Windows, or your favourite Linux distribution, you’ll find the app feels right at home, with native notifications, menus, and system integrations.

Download the 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.

Ready to give it a go? Download the app, log in, and enjoy a cleaner, more focused way to manage your email.
