Read-only mirror. This repo is a generated, release-time mirror of the MailKite monorepo (the private source of truth) — development doesn't happen here. Install from npm and open issues against the MailKite docs.

Install

npm install mailkite

Quickstart

import { MailKite } from "mailkite";

const mk = new MailKite(process.env.MAILKITE_API_KEY);

const { id, status } = await mk.send({
  from: "hello@myapp.ai",
  to: "ada@example.com",
  subject: "Your invoice #1042",
  html: "<p>Thanks! Receipt attached.</p>",
});

See: send.js

Give an agent its own inbox. Route inbound mail to a built-in inbox agent (the agent route action) and it answers, files, or escalates on its own — see https://mailkite.dev/docs/ai-agents.
