pennypost

Official Node.js SDK for PennyPost, the affordable email API. Zero dependencies. Fully typed. Node 18+.

npm install pennypost

import { PennyPost } from "pennypost";

const pp = new PennyPost("pp_live_<secret>");

const { accepted } = await pp.emails.send({
  from: "Receipts <[email protected]>",
  to: ["[email protected]"],
  subject: "Your order shipped",
  text: "Tracking inside.",
});

const email = await pp.emails.get(accepted[0].id); // full event timeline

Test keys (pp_test_<secret>) hit the same API, but no email is delivered. Sign up at app.pennypost.io and you have one in under a minute.

Also included: pp.emails.sendBatch([...]) (up to 100 messages, one request), cc/bcc on sends, pp.emails.list({ to, domain, key }), pp.suppressions.list/add/remove, the full Marketing Emails surface (pp.audiences, pp.contacts with custom properties, pp.broadcasts with markdown drafts, send-time filters, and sendTest), per-send idempotencyKey, and typed errors (PennyPostError with code, status, param, retryable).
