Idempotency, on by default
Every write takes an idempotency key. Retry a timed-out request as many times as you like — it resolves to one send, never two.

The email API for developers
A single, well-typed request from the SDK you already use. Delivery, retries, and logs are handled. You write the call and move on.
npm install endpointNo credit card. 3,000 emails a month on the free tier.
import { Endpoint } from "endpoint"; const endpoint = new Endpoint(process.env.EP_KEY); const { id } = await endpoint.emails.send({ from: "ci@acme.dev", to: "dev@example.com", subject: "Your build passed", html: "<b>All 214 checks green.</b>",});And this comes back
One request, one predictable JSON body, one request id you can grep for in the logs. No polling, no guessing what state the send is in.
$ endpoint emails send --to dev@example.com < HTTP/2 200 OK< x-request-id: req_5b1e9c2a { "id": "em_9f2c4a7d", "object": "email", "status": "delivered", "to": "dev@example.com", "created_at": "2026-09-20T18:04:11Z", "latency_ms": 38}Built for the boring parts
The things you would otherwise build twice and still get wrong — retries, signatures, a sandbox that tells the truth — are the product.
Every write takes an idempotency key. Retry a timed-out request as many times as you like — it resolves to one send, never two.
Signed events, exponential backoff for three days, and one-click replay from the dashboard. Your consumer can go down without losing a thing.
Test keys, seeded data, and the same latency profile as live. What passes in test behaves identically the moment you flip to production.
Thirty days of full request and response bodies, a copyable curl to reproduce any call, and latency traces down to the millisecond.
