Gotchas - check before you buy

Free tier caps test mailboxes at 100MB; messages don't persist long-term

Some users hit SMTP 'Greeting never received' errors; troubleshooting is on forums, not support

medium

Weak fit for inbound email testing — users switched tools for that

No public security page; evaluate carefully before pointing production-like data at it
