Together, these two features make it possible for you to send and receive emails from your applications. For example, you can use Email Service for: * Transactional emails (welcome messages, password resets, order confirmations) * Authentication flows (magic links, email verification, two-factor authentication) * Notifications and alerts * Custom email addresses (support@, contact@, orders@) * Emails as a mode of interaction for agents, such as send an email to create an issue in ticket tracking Access Email Service directly from Cloudflare Workers using [bindings](https://4f1c5cd2.previews.developers.cloudflare.com/email-service/api/send-emails/workers-api/), from any platform using the [REST API](https://4f1c5cd2.previews.developers.cloudflare.com/email-service/api/send-emails/rest-api/), or over [authenticated SMTP](https://4f1c5cd2.previews.developers.cloudflare.com/email-service/api/send-emails/smtp/): Send emails with the `EMAIL` binding and handle incoming emails with the `email()` handler in `src/index.ts`: ```ts interface Env { EMAIL: SendEmail; } export default { // Handle HTTP requests (Email Sending) async fetch(request, env, ctx): Promise { // Send a welcome email await env.EMAIL.send({ to: "user@example.com", from: "welcome@yourdomain.com", subject: "Welcome to our service!", html: "

Welcome!

", text: "Welcome! Thanks for signing up.", }); return new Response("Email sent successfully"); }, // Handle incoming emails (Email Routing) async email(message, env, ctx): Promise { // Forward to support team if (message.to.includes("support@yourdomain.com")) { await message.forward("team@yourdomain.com"); } // Send auto-reply await env.EMAIL.send({ to: message.from, from: "noreply@yourdomain.com", subject: "We received your message", html: "
