How to read your South.edu verification result

Every check returns one of three clear outcomes so you know exactly what to do with the address.

Passed - Safe to Send

The mailbox exists and accepts mail. Send with confidence, the address is deliverable.

Failed - Do Not Send

The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.

Unknown - Use Caution

The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.
