About Resend
Resend is the developer-focused transactional email service founded by Bu Kinoshita and Zeno Rocha (ex-Liferay, ex-Vercel) that's quickly become the smaller default for Next.js shops. The pitch is simple: a modern API, React Email templates as a first-class primitive, generous free tier (3k emails/mo, no card), and a UI that doesn't feel like a 2015 ESP. Deliverability is solid (no known issues with major inbox providers), and pricing scales linearly. The trade-off is product maturity — features like dedicated IPs are newer than the Postmark/SendGrid equivalents.
✓Best for
- Next.js and React teams that want the React Email integration as a first-class workflow
- Alternative SaaS sending receipts, password resets, and lifecycle email at modest volume
- Anyone migrating off SendGrid for a better DX without losing reliability
