Quick answer

Ethereal Email - Ethereal Email wins for most builders because it is easier to start with and more forgiving on basic testing workflows, while Debug Mail only pulls ahead if you need team collaboration and forwarding controls right away.

How the free tiers compare

These two free tiers solve the same core problem, but they optimize for different kinds of testing. Ethereal Email is the simpler sandbox: you can spin up as many test accounts as needed, get instant SMTP credentials with no signup friction, and inspect messages via public preview URLs or IMAP. Its main constraints are time-based retention, a 200 messages per hour cap on public accounts, and no inbound mail for those accounts. Debug Mail is narrower but more team-oriented. Its free tier allows only 1 project and 2 team members, but it does give unlimited test emails per day plus shared mailbox features and forwarding, which matters if your team is validating flows together. If you want the lowest-friction individual test inbox, Ethereal is the cleaner fit. If you need a small shared testing workspace, Debug Mail is more structured.
