What does Risky mean?

Risky means do not treat it as confirmed. Domain accepts unknown addresses: their server accepts every address. Accepted — limited verification: the mail server accepted this address, but there is no independent confirming signal. Accepted by receiving server: supporting signs are strong, but there is no mailbox-specific confirmation. Mailbox full: do not send right now. Only Confirmed is safe to send.

Risky is a status you can filter. It is not Valid with extra steps. The row claim is the short label, not the parent word.

What to do with Risky

For conservative outbound, export Valid only. If you accept more reach, use Valid + all catch-alls (use with caution); those catch-all rows remain Risky.

Four statuses: Valid vs Invalid vs Risky vs Unknown.
