Works on its own
Your email, on the machine you read it on.
Create an account Free for one person, indefinitely.
It is a real desktop application rather than a website in a frame. It runs on Windows, macOS and Linux and talks to whatever mailbox you already have over IMAP and SMTP, so there is nothing to migrate and no provider to leave.
Your mail is cached and indexed on your own machine, and searching it does not send it anywhere. That is a property of where the software runs rather than a promise about how we behave.
What the account adds is the half a program on your laptop cannot do for itself: the same settings and the same identity on every operating system it runs on, and a plan whose limits are the rows the software actually checks.
- Any mailbox you already have
- IMAP and SMTP, so there is nothing to move and nobody to leave.
- Your mail stays on your machine
- It is cached and searched where you read it, not copied to a server here.
- Windows, macOS and Linux
- One account across every one of them, so a second computer is a sign-in rather than a setup.
And the rest of it
Mail is one of 3, and they are on the same account. Nothing here needs the others to be useful.
