No. You pay 1 email credit only when GetProspect gives you a valid email you do not own yet. Nothing is charged when:
- no email is found,
- the only email we have is invalid or accept-all (GetProspect does not deliver those),
- you already own the email, for example because you revealed or saved that person before.
The same goes for mobiles: a phone credit is spent only when a number is found.
Verification is the one exception, because there you pay for the check itself. A single check is free when the result is accept-all or unknown. A bulk check costs 1 verification credit per unique address whatever the result. See How credits work for the full list.
