Both tools score catch-alls. The AI pass is the gap.
Credit where due: Clearout scores catch-all addresses with a confidence signal and a Safe to Send flag, which puts it ahead of most verifiers. So the question for a Clearout shortlister is not whether you get a score, it is what feeds the score.
Verifox runs a dedicated AI pass behind its 0-100 confidence score: mailbox-level signals layered on top of the 9-point engine, not a domain-level verdict stretched across every address at that domain. Two contacts at the same catch-all company can score 91 and 12. Test one on the catch-all email checker.
