What are catch-all emails?
As the name suggests, a catch-all address is designed to capture all emails sent to any non-existing email accounts on your domain, Most validation tools are unable to validate catch-all emails in real time
Is catch-all/accept-all emails the same?
Yes, they are essentially the same; it's similar to how various validation tools categorize emails under different names, Some common names include catch-all, risky, accept-all, guessed, and unknowns.
Why can't SMTP-based verification can't verify risky emails?
It is not possible to validate risky (catch-all/accept-all) emails with an SMTP-based validation tool because the entire purpose of having a catch-all email is to accept all types of emails. This makes it very difficult to verify, but we have a very unique system that makes it possible.
How are you better than other tools such as Neverbounce, clearout, etc.?
We validate risky emails at no extra cost, so that means we can validate more emails than any other email verification tool out there, and that too In real-time.
