Deliverable
Mailbox looks able to receive mail under enabled checks. Best default for accept and send.
Quality signals
Understand email quality with clear results and flags
ValidReach does not invent a black-box “score.” You get a top-level result plus quality flags so product and marketing can encode policy deliberately.

Top-level results
Three outcomes you can act on
Unknown is also returned when we cannot classify — and it never burns credits.
Risky
Worth a second look — often paired with disposable, accept-all, or similar signals.
Undeliverable
Do not send. Invalid syntax, no MX, or other hard failure signals.
Quality flags
Segment risk without guessing
Flags appear in the dashboard, list exports, and API — same vocabulary everywhere.
Disposable
Temporary or throwaway inbox providers.
Role
Team addresses like info@ or sales@ — often lower engagement.
Free
Consumer free-mail providers vs work domains.
Accept-all
Domain accepts any local part — validity is less certain.
