Resend is a developer-first transactional email API built by Resend Inc., a San Francisco company founded in 2023 by Zeno Rocha and Bu Kinoshita, the team behind the open-source React Email project. Resend is positioned as a modern alternative to SendGrid, Mailgun, and Postmark, with first-class React Email template support, audience and broadcast features, and SDKs for Node.js, Python, Ruby, PHP, and Go.
Templates are written as React components using the React Email library, allowing developers to compose email layouts with the same component model used in their web applications. Resend renders the React tree to HTML and plain text on the server before delivery. The platform also provides webhook event streams for delivery, open, click, bounce, and complaint events, plus an audience and broadcast feature for marketing-style sends without requiring a separate marketing tool.

Paid plans are Pro at $20/month (50,000 emails/month, multiple domains, 7-day retention), Pro 100k at $90/month (100,000 emails/month, 30-day retention), and Enterprise at quote-based pricing. Volume above included tiers is billed per email overage.
