Catch-All Domain Checker
Test if a domain is configured as a catch-all (accept-all). Find out if standard email verifiers will fail on a specific company.
How the Catch-All Domain Checker Works
The tool pings the domain's MX records with a randomized, non-existent email address (e.g., asdfgbhj@domain.com). If the server accepts it, the domain is confirmed as a catch-all.

Frequently Asked Questions
What does "catch-all" mean?
A catch-all domain accepts all emails sent to it, regardless of whether the specific user exists. This makes confirming specific addresses impossible without AI confidence scoring.
Why do I get false positives on catch-all domains?
Because the server lies and says "yes, that email exists" to every query. ZeroBounce AI uses alternative signals to predict true validity.
