OperatorYuki Nakazawa
PurposeA free tool that queries the world's major DNSBLs (spam blacklists) over DNS and shows their responses as they are. Listing and delisting are done by each list operator; this site cannot do either.
Consulting helpWe introduce providers who handle delisting requests, consulting and advice, and pass your inquiry on to them. This site may receive a referral fee from listed providers. Any contract is made directly between you and the provider; this site is not a party to it.
ContactFor delisting help or advice, please use the consulting form.
