Send email with Express

A server-side call to the SendSend API from your Express app.

  1. Create a test API key in the dashboard first: it never delivers real email. Switch to a live key once your domain is verified.
  2. Export SENDSEND_API_KEY in the environment that runs the server, or load it with a .env file.
  3. Add this to server.js:
import express from 'express';

const app = express();
app.use(express.json());

app.post('/send', async (req, res) => {
  const r = await fetch('https://api.sendsend.email/v1/emails', {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${process.env.SENDSEND_API_KEY}`,
      'Content-Type': 'application/json',
      'Idempotency-Key': crypto.randomUUID(),
    },
    body: JSON.stringify({ from: 'Acme <hello@mail.acme.com>', to: [req.body.to], subject: 'Hello from Express', text: 'It works!' }),
  });
  res.status(r.status).json(await r.json());
});

app.listen(3000);

Good to know
