Read your email
like messages.
ThreadMail turns your inbox into friendly chat-style conversations — one thread per person, one tap to tidy up, and all your accounts side by side.
Your inbox, finally readable
Email scatters one exchange across days and buries it in noise. ThreadMail regroups everything around the people and services you actually talk to.
Conversations, not lists
Every correspondent becomes one chat — even services that write from several addresses stay in a single thread.
One-tap cleanup
Done with a sender? Delete the whole conversation in one action instead of picking off messages one by one.
All your accounts, one app
Switch mailboxes from a messenger-style sidebar. Several accounts feel like one tidy app, not five browser tabs.
Set up in a minute
Type your address and ThreadMail finds your mail server's settings for you. Gmail signs in with Google in two clicks.
Fast, even offline
Your mail is synced to your computer, so everything opens instantly — on the train, on a plane, anywhere.
Reply like you chat
Type at the bottom of the conversation, attach files, hit Send. That's it.
Private by design
ThreadMail lives on your computer and talks only to your mail provider. No ThreadMail account, no cloud, no tracking.
Your passwords stay yours
Credentials are kept in your operating system's secure keychain — never in a file, never on our servers (we don't have any).
Reading leaves no trace
Mail is only marked as read when you open it — syncing in the background never touches your read status.
Free & open source
Built in the open. No ads, no premium tier, no strings — and anyone can check exactly what the app does.
Get ThreadMail
Native installers for every desktop — and the app keeps itself up to date.
Checksums and the full build list are in the release manifest; every installer has a .sha256 file beside it.
