Resend is great. Here's when you'd self-host it instead.

Let's get the disclaimer out of the way, because we mean it: Resend is a very good product. The API is clean, the React Email integration is the nicest templating story in the space, the dashboard is polished, and you can go from zero to a delivered email in minutes without thinking about DKIM. If you want a managed transactional sender and you never want to touch deliverability plumbing, Resend is a defensible default and you should probably use it.
