@lesto/mail

Queued, transport-agnostic email built on @lesto/queue.

Part of Lesto, the batteries-included, agent-native fullstack framework.

bun add @lesto/mail

import { Mailer } from "@lesto/mail";

const mailer = new Mailer({ queue, transport, render, defaultFrom: "[email protected]" });

const welcome = mailer.template("welcome", (p: { to: string; name: string }) => ({
  to: p.to,
  subject: "Welcome",
  react: <Welcome name={p.name} />,
}));

welcome.send({ to: "[email protected]", name: "Ada" }); // typed; enqueued; a worker delivers it

Bring your own renderer via the render hook (e.g. react-email in one line) — the package depends on neither React nor react-email. Two transports ship: createSmtpTransport (Node) and createFetchProviderTransport (Workers-compatible).
