About

Resend is the email API for developers. Build, test, and deliver transactional emails at scale with a modern developer experience and beautiful email templates.

Target Audience: Backend and full-stack developers at SaaS companies who need to reliably send transactional email from application code. Product engineers and startup teams use Resend because it combines an API, template workflow, and delivery logs without requiring them to run their own email server.
Not ideal for: Teams that need a full marketing automation platform, newsletter CRM, or drag-and-drop bulk campaign suite should not use Resend, because it is optimized for developer-built transactional email delivery.

What makes it different

  • Native React Email support for building transactional templates as components instead of hand-coded HTML
  • Simple email-sending API with official SDKs for integrating email delivery directly into application code
  • Built-in dashboard with message logs and delivery status so teams can debug failed sends quickly
  • Domain authentication and branded sending domains to help improve inbox placement and trust
