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.
Judged purely as an API. What the request contract guarantees on retry, how complete the webhook event coverage is, whether suppressions are readable and writable programmatically, and how much the message log retains when something needs debugging in production.
Against high-frequency programmatic sends where a missed delivery is a product failure, Ethereal Email covers none of the capabilities this audience leans on (idempotency keys, webhook coverage, event stream, the suppressions API, batch sending, and SDK breadth), so it fits only where those needs are genuinely absent.
