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.
At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.
Against a waitlist, a launch announcement, onboarding email, and the first transactional sends, Ethereal Email covers developer experience, and does not cover scheduling, SDK breadth, and webhook coverage. Whether that gap matters depends on how central those are to the build.
