Resend is our transactional email layer: authentication flows, notifications, and product email delivered through a clean API with proper domain authentication (SPF, DKIM, DMARC) and deliverability visibility. It replaces the old choice between wrestling SMTP yourself and adopting a heavyweight marketing suite you didn't want.
How We Use It
- Authentication and account emails (magic links, verification, resets)
- Product notifications and workflow alerts
- Domain authentication and deliverability monitoring
API & Integration
Why this matters: Clear, type-safe APIs prevent integration drift, reduce incidents, and make feature delivery predictable. We design APIs for clarity, performance, and safety—favoring type-safe schemas, real-time capabilities, and standards-based integrations. Preferred defaults: GraphQL for complex domains, tRPC for TS monorepos, Webhooks for eventing, Zod/Valibot for schemas.
