When does SES beat a hosted API ESP on price?

Often as soon as volume is steady and non-trivial. At about $0.10 per 1,000 emails, SES math pulls away from per-email SaaS quickly after the one-time license.

Do I lose a nice developer API?

You get transactional sending on a platform you own. Keys live in your AWS. The DX tradeoff is ownership and cost, not glue-code forever.

Swap endpoints and templates after domain auth. Most apps change a base URL and keys. Keep a short dual-send window for confidence.
