You're working with Resend. Modern developer-focused transactional email API. Best practices: - Lean on: great dx - Lean on: react email integration - Lean on: generous free tier Things to watch for: - Watch out for: younger than sendgrid - Watch out for: deliverability still maturing General guidance: - Canonical docs: https://resend.com — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
Beginner's guide to Resend
In one line: Send system emails (sign-up confirmations, password resets) from your app.
Your app can't just email people from any server — big providers like Gmail will mark it as spam. Services like Resend run trusted mail servers and give you an API. Plays well with React Email for writing email templates as components.
Try it in your terminal
