## Overview

Resend is an email delivery platform built for developers who need to send transactional and marketing emails at scale. It offers SDKs for Node.js, Python, Ruby, Go, Rust, PHP, Elixir, Java, and more, plus native React email templating via its open-source react-email library. Pricing is not publicly listed on the scraped page.

Delivering email reliably -- without landing in spam -- is a persistent infrastructure problem for engineering teams. Resend addresses this with a clean REST API, modular webhooks for real-time delivery events (delivered, opened, bounced, clicked), a test mode for safe experimentation, contact management with import tools, and broadcast analytics so teams can track audience engagement. The result is a self-contained email stack that fits directly into existing codebases.

## Key points

- SDKs for 10+ languages plus SMTP/REST, with a test mode for safe API experimentation
- React-based email templating (react-email) eliminates manual HTML table layouts
- Modular webhooks deliver real-time notifications for delivery, opens, bounces, and clicks
