PrüfergebnisseWhat 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.
PrüfergebnisseWhy is an address marked catch-all instead of valid?
Catch-all means the domain accepts every recipient without confirming whether the specific mailbox exists.
PrüfergebnisseWhy 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.
PrüfergebnisseWhat 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.
PrüfergebnisseWhy did my result change when I re-verified the same address?
Cached results and temporary mail-server conditions can explain why a later verification returns a different status.
Abrechnung und GuthabenWhich results consume credits?
See which verification outcomes cost one credit and which results are always returned free of charge.

Disposable-domain detection is free unless you explicitly request and complete a full live SMTP verification.

Repeat checks for the same account and address are free within 24 hours unless you request a force refresh.
