Alongside the main label, some addresses carry an extra signal — a small badge that highlights something worth knowing.
What we check
When live domain intelligence is available, we look for domains listed as abuse sources and domains that have only recently appeared. Either can be a reason to slow down and review the address before sending.
What the signal means
A domain warning is not proof that one specific address is harmful. It is extra context about the domain. We lower the result to risky and show the reason so you can make the final decision.
Heads up
Treat domain warnings seriously, especially on old, bought, or unfamiliar lists. Review the source before you send.
