Resend

Modern and Developer-First Transactional Email Service

What is Resend?

Resend is a modern transactional email service designed specifically for developers. Unlike legacy email providers (like SendGrid or Amazon SES), Resend focuses on clean APIs, highly readable delivery logs, and first-class integration with the React Email framework, allowing you to build beautiful email templates directly as code components.

Why Choose Resend?

πŸ’… React Email Support

Create and preview your email templates using modern React components without dealing with complex pure HTML tables.

πŸ“ˆ High Deliverability

Optimized infrastructure with easy SPF, DKIM, and DMARC configuration, keeping your emails out of the spam folder.

πŸ” Real-time Webhooks & Logs

Track when emails are sent, delivered, opened, or clicked. Register webhooks to trigger automation in your app.

πŸ”‘ Granular API Keys

Configure keys with restricted permissions (e.g. sending only) and restrict keys to specific sending domains.

Practical Example: Sending via Node.js

Here is a simple example of how to dispatch a transactional email in a Next.js API route or any Node.js backend:

import { Resend } from 'resend';

const resend = new Resend(process.env.RESEND_API_KEY);

async function sendWelcomeEmail(userEmail, userName) {
  try {
    const data = await resend.emails.send({
      from: 'Support ',
      to: userEmail,
      subject: 'Welcome to our SaaS!',
      html: `Hi ${userName},

We are thrilled to have you on board!

` }); console.log('Email sent successfully! ID:', data.id); } catch (error) { console.error('Failed to send email:', error); } }
