How to choose (fast)

  1. Transactional-only + deliverability focus? Start with Postmark.
  2. Need SMTP + API flexibility? Mailgun is a common default.
  3. Lowest vendor cost at scale? SES, if your team can run the setup.
  4. Marketing + transactional in one? Brevo can be simpler.

We separate vendor cost from ops cost. Unknown stays unknown until verified.
