AWS SES vs Resend
AWS SES and Resend both answer the same question: how do your emails actually get delivered? Amazon's raw sending service: the cheapest way to move mail, with everything above the SMTP layer left to you. 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.
