Resend Has a Free Email API — Send 3,000 Emails/Month With 3 Lines of Code

Why Developers Hate Email

SendGrid wants $20/month for basic features. AWS SES requires a PhD in IAM policies. Mailgun's pricing page needs a spreadsheet to decode.

You just want to send a password reset email.

Resend: Email for Developers Who Value Their Time

Resend is an email API built by the creator of React Email. It does one thing well: send transactional emails with a developer-first API.

Free Tier

  • 3,000 emails/month (free forever)
  • 100 emails/day limit
  • Custom domain support
  • No credit card required

Send an Email in 3 Lines 

import { Resend } from 'resend';
const resend = new Resend('re_123456');

await resend.emails.send({
  from: 'you@yourdomain.com',
  to: 'user@example.com',
  subject: 'Welcome!',
  html: '<h1>Welcome aboard</h1>'
});
Enter fullscreen mode Exit fullscreen mode

That is it. No SMTP configuration. No template engines. No 47-step setup wizard.

Python? Also 3 Lines 

import resend
resend.api_key = 're_123456'

resend.Emails.send({
    'from': 'you@yourdomain.com',
    'to': 'user@example.com',
    'subject': 'Welcome!',
    'html': '<h1>Welcome aboard</h1>'
})
Enter fullscreen mode Exit fullscreen mode

Why Developers Are Switching

1. React Email Integration

Build email templates with React components. No more HTML tables from 2005.

import { Html, Button, Text } from '@react-email/components';

export default function WelcomeEmail({ name }) {
  return (
    <Html>
      <Text>Hi {name}, welcome to our platform!</Text>
      <Button href="https://app.example.com">
        Get Started
      </Button>
    </Html>
  );
}
Enter fullscreen mode Exit fullscreen mode

2. Webhook Events

Know when emails are delivered, opened, clicked, or bounced. Real-time webhooks, not batch reports from yesterday.

3. Domain Verification in Minutes

Add 3 DNS records. Resend verifies them automatically. You are sending from your@company.com in under 10 minutes.

Resend vs The Competition

Feature Resend (Free) SendGrid (Free) AWS SES
Monthly emails 3,000 100/day 62,000*
Setup time 5 min 30 min 2+ hours
React templates Yes No No
API simplicity 3 lines 10+ lines 20+ lines
Credit card No Yes Yes

*AWS SES free tier only from EC2 instances

When to Use Something Else

  • 100K+ emails/day: AWS SES is cheaper at scale
  • Marketing campaigns: Use Mailchimp or ConvertKit
  • Complex automation: SendGrid or Postmark have more workflow features

For transactional emails (password resets, notifications, receipts), Resend is the fastest path from zero to sent.
