AI
Three doors. One send.
People click Send. Machines should not have to. mittera is being built so an app, a hosted agent, or a toolbox like MCP can send mail the same way — with your key, from your domain.
Get startedMachine to machine
Your app talks to mittera with a key. A receipt, a reset, a notice — sent because something happened, not because someone clicked Send.
Hosted agent
A Briven-shaped agent on a server, with a job and a key. It sends on your behalf. You are not sitting in the chat.
MCP
The same send tools, in the language Cursor, Claude and Grok already speak. Live now — same key as the API, no second door.
Start sending this afternoon.
The free plan is the trial. The AI doors share the same key.
