add-emails

To send transactional emails in Next.js, you integrate the Resend client and React Email components on the server side. You configure environment keys, wire a migrations file for Supabase, and use typed React Email templates for rendering and delivery.

Handling email unsubscribes for transactional notifications is best done using RFC 8058 unsubscribe handling. This approach preserves deliverability by embedding list-unsubscribe headers directly into your React Email templates and batch sending logic.

Yes, you can use React Email components to template transactional emails in a Next.js project. React Email provides polished, typed components that render the email UI, which the Resend client then uses to send onboarding and notification messages.

Yes, you need a migrations file to manage unsubscribe tokens in Supabase. The integration requires a database migrations file to store unsubscribe preferences and link them with the RFC 8058 unsubscribe headers processed during batch sending.

Resend supports batch sending with rate limiting for Next.js applications. This integration applies rate limiting during batch sends to manage delivery quotas and maintain reliable transactional email communication for onboarding and notifications.
