Features

Everything has a shortcut.

Kestrel is built around the keyboard. Once your hands learn a few keys, you get through your inbox in a fraction of the time.

⌘K

A command for everything

Forget a shortcut? The command palette lists every action and finds it as you type. ? shows them all.

Tab

Primary and Other

Mail from people you know lands in Primary. Newsletters, receipts and notifications are labelled and kept in Other.

H

Remind me later

Not ready to deal with it? Snooze a conversation, and it comes back to your inbox when you choose.

Z

Undo anything

Marked done by mistake? Sent too soon? Press Z. Sends wait a few seconds so you can take them back.

⌘1

Gmail and Outlook together

Connect personal and work accounts from Google and Microsoft 365, and jump between them with one key.

⌘U

Unsubscribe in one key

Kestrel uses the mailing list's own one-click unsubscribe where it can, then clears the conversation away.

Reading and replying

Read, reply and move on.

Conversations open in a calm reading view, with the sender's details and your history with them alongside.

  • R reply, A reply all, F forward, ⌘↵ send
  • HTML email adapts to dark mode, or shows as designed with D
