description Resend Overview

Resend is a modern, developer-focused API for sending transactional emails. Instead of managing SMTP credentials or dealing with complex email service provider overhead, you send emails via a simple API call. This approach treats email delivery as a first-class, consumable service, perfect for SaaS applications that need reliable, high-volume communication without infrastructure headaches.

help Resend FAQ

Can Resend send email from my own domain?

Yes. You verify a domain by adding the DNS records Resend provides, including SPF and DKIM records, and then send from an address on that domain.

Does Resend require SMTP, or can I use an API?

Resend is built around an HTTPS API, so a transactional email can be sent with an API key and a single request. It also provides an SMTP interface for applications that cannot use its REST API directly.

Can Resend send React-based email templates?

Yes. Resend is closely integrated with React Email, an open-source library for building email markup from React components. You can render components for messages such as sign-in links, receipts, and account notifications.

How does Resend differ from SendGrid or Amazon SES?

Resend emphasizes a streamlined developer API and React Email workflow, while SendGrid includes a broader marketing platform and Amazon SES is closely tied to AWS infrastructure. All three can deliver transactional email, but their setup, dashboards, and template workflows differ.
