Recipe: Send email from the Edge

Send transactional email from Cloudflare Workers or other Edge runtimes with Notify’s HTTPS API.

Edge runtimes speak fetch. Notify is a single HTTPS POST — no Node-only SMTP sockets required.

export default {
  async fetch(request: Request, env: { NOTIFY_API_KEY: string }) {
    const res = await fetch('https://notify.cx/api/email/send', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'x-api-key': env.NOTIFY_API_KEY
      },
      body: JSON.stringify({
        to: 'user@example.com',
        subject: 'Hello from the edge',
        message: '<p>Sent from a Worker.</p>',
        from: 'noreply@your-verified-domain.com'
      })
    });

    return new Response(await res.text(), { status: res.status });
  }
};

Store the key in Worker secrets / Edge env — not in the client bundle.

Where to next?
