Postmark and Resend both answer the same question: how do your emails actually get delivered? Transactional-only sender with an obsessive focus on inbox placement and fast delivery. Modern transactional email API from the team behind React Email, built around writing templates as components. Both cover the transactional email layer competently, so the decision comes down to which set of tradeoffs you would rather live with for the next two years.

Tradeoffs
Neither is better in the abstract. Both cover the transactional email layer competently, so the decision comes down to which set of tradeoffs you would rather live with for the next two years. Pick the one whose downside you can absorb, because both upsides are real.
Refuses most bulk marketing mail, so you need a second tool for campaigns. No meaningful free tier, so hobby projects pay from day one.
Younger sender reputation infrastructure than providers that have been warming addresses for a decade. Focused on transactional mail, so marketing campaign features are thin.
Usually, at a cost that grows with how much of your product leans on the transactional email layer. Plan for it in the data model, not in the framework, and the switch stays survivable.
