Next.js + Resend: Transactional Email Setup

Resend is the cleanest transactional email integration for Next.js App Router — React email templates, a simple API, and a dedicated sender domain in minutes.

Use Cases
  1. Welcome and onboarding emails triggered on user signup
  2. Stripe webhook → confirmation email on payment success
  3. Password reset and magic link emails
  4. Notification digests from a Next.js cron or API route
Implementation

Create a Next.js Route Handler (app/api/send/route.ts). Import Resend, initialize with RESEND_API_KEY (server-only env var). Use react-email for typed React templates. Call resend.emails.send() from server components and API routes only — never client-side. Verify the sender domain in Resend dashboard and add the DKIM/SPF records to your DNS before going to production.
