Sending a lot of email without hitting the rate limit or the spam folder
Resend allows a couple of requests a second by default. Use the batch endpoint, add backoff for 429s, keep one idempotency key per recipient, and never batch a magic link.

Bounces and spam complaints: listen, or lose the inbox for everyone
A hard bounce means the mailbox is gone. Keep sending and mailbox providers downgrade every message from your domain. Wire the webhook, suppress permanently, and never suppress on a soft bounce.
