Resend is our most popular email integration, and is well-loved by developers. It's the perfect compliment to Supabase Auth.
Paul Copplestone
Founder & CEO of Supabase
Integrate with Supabase Auth
Use the native Supabase integration or configure the SMTP credentials of your project to send unlimited emails.
Send emails from Supabase Edge Functions
Create a server-side TypeScript function, distributed globally at the edge, and send custom emails with low latency.
import { serve } from "https://deno.land/std@0.190.0/http/server.ts";const RESEND_API_KEY = 're_xxxxxxxxx';const handler = async (_request: Request): Promise<Response> => {const res = await fetch('https://api.resend.com/emails', {method: 'POST',headers: {'Content-Type': 'application/json','Authorization': `Bearer ${RESEND_API_KEY}`},body: JSON.stringify({from: 'onboarding@resend.dev',to: 'delivered@resend.dev',subject: 'Hello World',html: '<strong>it works!</strong>',})});const data = await res.json();return new Response(JSON.stringify(data), {status: 200,headers: {'Content-Type': 'application/json',},});};serve(handler);

Vlad MatsiiakoCo-founder of Infisical"As a developer I love the approach that the Resend team is taking. Its so refreshing. They are also extremely user-centric and helpful in terms of getting you up and running, sending beautiful emails that deliver."
Hahnbee LeeCo-Founder at Mintlify"We value tools that feel stable, well thought out, and aligned with the standards we expect across our stack. Resend meets those expectations.
