Mailcycle - Private Email

Email for every device & agent

Free · In‑App Purchases

Give every phone, tablet, scanner and AI agent its own email address. Pair devices by QR code, connect agents over MCP, and keep every message sealed to your key. Private email for every device and every AI agent. Mailcycle gives phones, tablets, scanners, test devices and AI agents their own email addresses, all managed from one account, with every message sealed to a key only your devices hold. AN ADDRESS FOR EVERY DEVICE Pair a phone, tablet or computer with a QR code or an 8-digit code, one at a time or a whole batch at once. Each device gets only the addresses you assign it and receives their mail directly. It needs no account or password of its own. Tag devices, group them, see which are online, and remove one in a tap. INBOXES FOR AI AGENTS Give an AI agent its own address and connect it over MCP from any compatible client. Choose what it may do: reply only, send to anyone, or read only. Its mail is sealed like yours, and you can take its address away at any time. BUILT FOR AUTOMATION An API, webhooks, a live event stream and SDKs for TypeScript, Python, Go and Rust let your own software create addresses, receive mail and act on it. Use our domains or bring your own. PRIVATE BY DESIGN Your account is a twelve-word recovery phrase made on your phone: no email, name or password. Each address has its own key, derived on your device. Our mail server seals every incoming message to that key before anything is stored. What we keep is ciphertext. THE LIMIT, STATED PLAINLY Email to and from ordinary addresses travels as plain text between mail servers. Mail passes through our servers in the clear for the length of one request, and the copy we keep is sealed. The addresses themselves, arrival times and sizes stay readable to us, because delivery needs them. TRACKERS NEVER FIRE Remote content in mail is never fetched. Tracking pixels are stripped before a message is shown, and Mailcycle tells you which host wanted it. DELETION IS THE DEFAULT Each address keeps mail for 24 hours, 7 days, 30 days or 90 days, then deletes it. Export your data or delete your account from Settings at any time. ALSO • Face ID, Touch ID or a six-digit passcode to lock the app • See and end your signed-in sessions • Push notifications with fixed text: never a sender, subject or message • No ads and no analytics in the app PLANS Free has three addresses and one device, and receives mail. Paid plans add sending, more addresses and devices, AI agents, webhooks, custom domains and team access. They are monthly subscriptions that renew automatically until you cancel in your Apple Account settings.
