Overview
Resend is a developer-first email API platform founded in 2022 and publicly launched in January 2023. Built by a fully remote team headquartered in San Francisco, it enables engineers to send transactional and marketing emails reliably via a clean REST API, SMTP relay, and official SDKs across nine programming languages. Its flagship open-source project, React Email, lets developers build cross-client email templates as React components, eliminating legacy HTML table layouts. Resend handles deliverability infrastructure including DKIM/SPF/DMARC authentication, managed dedicated IPs, multi-region sending, real-time webhooks, and proactive blocklist monitoring. Backed by Andreessen Horowitz and Y Combinator with $21.5M raised, the platform has attracted over 200,000 developers and customers including Warner Bros., eBay, Replit, and A24 Films.
Resend is an email API platform designed for developers to build, test, and deliver transactional and marketing emails at scale, powered by React Email templates, multi-region infrastructure, and a clean developer experience.
