Integrate inboxes easily in minutes

Give your app or agent an inbox with a few lines of code. Build it yourself, or let AI guide the integration and setup.

const response = await fetch("https://api.mailactor.com/v1/inboxes", {
  method: "POST",
  headers: {
    "content-type": "application/json",
    "x-api-key": process.env.MAILACTOR_API_KEY,
  },
  body: JSON.stringify({ localPart: "research-agent" }),
});

if (!response.ok) throw new Error(`Mailactor returned ${response.status}`);
const inbox = await response.json();
console.log(inbox.address);

Connect your agents to the world. One inbox, every conversation.

Encrypted at rest

Your agent’s conversations are encrypted in storage, with keys unique to your organization.

EU hosted by default
