Email at the speed of thought

Tempo is a keyboard-first email client for macOS. Every account lands in one unified inbox, and your mail is indexed on your Mac, so folders, threads and search open before you've finished reaching for them.

Built for heavy inboxes

Everything you need, nothing in the way

Tempo is made for people who live in their inbox. Every action has a key, every account sits in one list, and nothing waits on a server round trip.

One unified inbox

Work, personal and client accounts in a single list, colour-coded by account and grouped into Primary, Calendar and more. Switch to Unfiltered when you want to see everything.

Keyboard first

J and K to move, E to archive, R to reply, G I to jump to your inbox. Every shortcut can be remapped in settings.

Instant local search

Messages and threads are indexed on your Mac. Search returns its first results in under 200 ms and works offline.

Sleep conversations

Not ready to deal with it? Put a conversation to sleep and it comes back to your inbox when you are.

Undo send

Sent messages wait in the Outbox for 10 or 30 seconds, so you can pull back the one with the missing attachment.

Rules & quiet hours

Sort incoming mail with rules and labels. Mute notifications overnight and still let VIPs through.

Speed is the point

Every interaction has a budget

Tempo's core is written in Rust and every common action has a latency target. Tests fail the build when one is missed.

  • Spinners while every folder loads from the server.

Command palette

Press ⌘K and keep typing

Search mail, jump to a folder, act on the open conversation or change a setting from the same box. You never need to reach for the mouse.

  • Fuzzy matching across commands, folders and labels
  • Shows the shortcut for each command as you go
  • Compose in a pop-out window or inline under the thread
Private by default

Trackers stay blocked until you say otherwise

Remote images are how senders know you opened their email. Tempo blocks them by default, and you can load them once or always trust a sender.

  • Trusted senders always load images, everyone else doesn't
  • Links whose text shows a different address ask before opening
  • Your mail index lives on your Mac, with a retention window you control
