If you are developers picking email infrastructure
The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.
The order above is the general editorial ranking. Re-sorted against developer experience, SDK breadth, and idempotency keys, the shortlist for password resets, receipts, and magic links shipped from application code becomes Buttondown, Loops, and Kit. That differs from the headline order, which weighs all audiences together.
