Ethereal Email
Throwaway SMTP accounts on demand.
Ethereal Email is a free fake SMTP service that creates throwaway accounts via API. Run by the Nodemailer team; perfect for CI and quick tests.
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.
Against password resets, receipts, and magic links shipped from application code, Ethereal Email covers developer experience, and does not cover SDK breadth, idempotency keys, event stream, and webhook coverage. Whether that gap matters depends on how central those are to the build.
