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.
Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.
Against behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue, Ethereal Email covers multi-tenant support, and does not cover scheduling, event stream, and the suppressions API. Whether that gap matters depends on how central those are to the build.
