Quick Start

npm install resend

import { Resend } from 'resend';
const resend = new Resend('re_your_api_key');

  from: 'hello@yourdomain.com',
  to: 'user@example.com',
  subject: 'Welcome!',
  react: <WelcomeEmail name="John" />
});

Why Developers Choose It Over SendGrid

SendGrid's API is complex and their dashboard feels like 2010. Resend:

React Email — design emails like React components, not HTML tables
Modern DX — clean API, great docs, TypeScript-first
Better deliverability — purpose-built for transactional email
Simpler pricing — 3K free, then $20/mo for 50K emails

A SaaS founder was spending 2 days building HTML email templates for SendGrid. With Resend's React Email, they built 12 transactional templates in 3 hours — and the emails look perfect in every client.
