Your email should belong to you, not to the company that hosts it. Mailstr makes that real. You get a name@mailstr.app address that runs on Nostr and is tied to a keypair you control instead of an account a provider owns. You sign in with your keys, so there's no password and no phone number to hand over.
Mail sent to your address is encrypted and stored on the relays you choose, and only your key can read it. Write to other Nostr users directly, or to any ordinary email address through the bridge. It's all built on an open spec, so you can open the same mailbox in other compatible clients, switch relays, or leave for good — your mail follows your key, not our servers.
Claiming your address is a one-time payment. No subscription, no data harvesting, and no one reading over your shoulder.
