VerificatieresultatenWhat does an "unknown" result mean, and what should I do with it?
Unknown means the receiving mail system did not provide a reliable answer; it does not mean the address is bad.
VerificatieresultatenWhy is an address marked catch-all instead of valid?
Catch-all means the domain accepts every recipient without confirming whether the specific mailbox exists.
VerificatieresultatenWhy was an address I believe is active marked "invalid"?
Invalid is based on a concrete rejection from the receiving server, not a guess about the mailbox.
VerificatieresultatenWhat does the "score" in the result mean?
The 0.0–1.0 score reflects deliverability confidence and should always be read together with the status.

Cached results and temporary mail-server conditions can explain why a later verification returns a different status.
