Next.js+Resend
Stack IntegrationNext.js + Resend: Production Email Architecture
Resend pairs with Next.js App Router to deliver transactional emails via React components — typed templates, reliable delivery, and sender domain authentication in one API.
Use Cases
- Transactional emails triggered from Next.js API Route Handlers
- React Email templates shared between email and web UI components
- Bulk notification emails triggered by Supabase or database events
- Automated sequences for onboarding, trial expiry, and billing events
Implementation
Create reusable React Email components in an `emails/` directory and import them into Route Handlers. Initialize Resend with the API key from a server-only environment variable. Call `resend.emails.send()` server-side only — never in client components or browser-facing code. Configure your sender domain's DKIM and SPF records in DNS before sending to real users; Resend's domain verification dashboard provides the exact records to add.
