What is Resend?

Resend is the modern email API built for developers who want to send transactional emails without the pain of legacy providers like SendGrid or Mailgun. With a clean REST API, official SDKs for Node.js, Python, Ruby, Go, and PHP, and a React Email integration for building beautiful HTML emails with components, Resend makes email a joy to implement. Its generous free tier (3,000 emails/month), instant setup, and excellent deliverability have made it the fastest-growing email API in the developer community.
