Open, then sync
Your inbox appears from local cache while new mail arrives in the background. No blank page waiting on the network.
Fast. Minimal. Native.
Mail without
the wait.
Feather Mail opens from a local cache and keeps synchronization in the background. A focused Linux-native interface leaves you with the message, not the machinery.

Speed you can feel
Fast in the ways that matter.
Only what you need
Three calm panes, one clear accent and no engagement clutter. Several mailboxes become one simple workflow.
Native and direct
GTK4 controls and concise keyboard paths make compose, search, archive and reply feel immediate on Linux.
Minimal by design
Everything close. Nothing in the way.
Switch mailboxes, search every account or compose a reply without changing context. Offline actions wait quietly and continue when the network returns.
Private by construction
Your inbox is not a data source.
- No telemetry.There is no opt-in because nothing is collected.
- Remote images blocked.Tracking pixels and network images stay off until you choose otherwise.
- Secrets in the keyring.Passwords and tokens never go into SQLite, logs or MCP responses.
- HTML isolated.JavaScript is off; mail CSS and links pass explicit safety policies.
Open source · Linux native
Less waiting. Less interface. More mail.
