Results you can trust
We tell you what we know and what we cannot know — and we charge only for real answers. Our rules are published, not hidden in small print.
Format, domain and mail-server checks are facts. A catch-all domain is reported as catch-all, never as valid.
Duplicates and errors on our side are never charged. Every credit you spend is listed in your account.
Our status page is measured from the live system, not typed by hand.
Resell under your own brand
