Integrate into any Astro site

Resend seamlessly integrates into any Astro site via the Node SDK or API endpoints. Add an SSR adapter and send emails, create contacts, and more safely from the server in any deployment environment Astro supports.

Get startedDocumentation
import type { APIRoute } from "astro";
import { Resend } from 'resend';


const resend = new Resend(import.meta.env.RESEND_API_KEY);


export const POST: APIRoute = async ({ request }) => {
  const { email } = await request.json();


  const { data, error } = await resend.emails.send({
 	 from: 'Acme <onboarding@resend.dev>',
 	 to: [email],
 	 subject: 'Hello world',
 	 html: '<strong>It works!</strong>',
  });


  return new Response(JSON.stringify(data));

Enhanced for React Devs

Astro's React adapter is a perfect match for react.email, our collection of high-quality, unstyled components for creating beautiful emails using TypeScript. Forget about inconsistencies with different email clients.

import { Html, Button } from 'react-email';
import * as React from 'react';


interface EmailProps {
  link: string;
}


export const Email: React.FC = ({
  link,
}) => (
  <Html lang="en" dir="ltr">
    <Button href={link} style={{ color: '#61dafb' }}>
      Click me
    </Button>
  </Html>
);
