Resend review and pricing

Modern transactional email built for React, Next.js, and the TypeScript stack.

By Resend, Inc. · Founded 2023 · San Francisco, CA · private

Resend is the youngest credible entrant in the category and has absorbed a disproportionate share of new dev mindshare since launch in 2023. Founded by Zeno Rocha (ex-WorkOS) and team, Resend raised an $18M Series A led by Sequoia in 2024 and built the React-Email component library that has become standard tooling for Next.js apps. The DX is the deciding factor: TypeScript SDK with proper types, React-Email components, a clean dashboard, and a free tier of 3,000 emails/month that is genuinely usable for small projects. The trade is that the company is two years old, so the long-tail track record (multi-year deliverability under stress, support at scale) is still being established.
