Our community deploys Astro sites just about everywhere. Whether you're on a Node server, a serverless function, or even a Cloudflare worker, I love how Resend just works.

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.
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));}
import { defineAction } from 'astro:actions';import { z } from 'astro:schema';import { Resend } from 'resend';const resend = new Resend(import.meta.env.RESEND_API_KEY);export const server = {send: defineAction({accept: 'form',input: z.object({email: z.string().email(),}),handler: async ({ email }) => {const { data, error } = await resend.emails.send({from: 'Acme <onboarding@resend.dev>',to: [email],subject: 'Hello world',html: '<strong>It works!</strong>',});return data;},}),};
Send Form Emails with Astro Actions
Integrate Resend with Astro Actions for sending email with type-safe backend functions. Handle form submissions with web defaults in SSR and progressively add client-side JavaScript for a better user experience.
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/components';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>);
