About Blacklist Lookup

Please enter an IP address or domain name below to check if it is blacklisted. This Blacklist Lookup tool will check if your site is banned on specific databases and will also flag any anti-spam databases. If spam hits your website, search engines may also blacklist your site's IP address for security purposes. Sometimes, webmasters might not be aware that search engines have banned their website's IP. If your site is getting deindexed from search engines or if you see a decline in your organic traffic, use our Blacklist Lookup Tool to check if your website is blacklisted or not.


What is a blacklist?

Spam email is a huge issue online, with many sources available on the internet that publicly list known servers that send spam. These lists, commonly referred to as blacklists, are used by many email providers to help block spam emails sent to their users. A blacklist is a collection of IP addresses that are believed to distribute spam; emails from these addresses are either blocked or routed to the recipient's spam folder. Blacklists are identified by spam filters, which use set criteria to identify emails believed to be of a malicious or spammy nature. Ensuring that emails are delivered and blacklists are avoided is the first critical step to successful email marketing


Importance of Using a Blacklist Lookup

The primary purpose of domain blacklist checking is to block mail. Most e-mail servers these days have DNSBL support built in or as a plug-in, which allows a server administrator to block all emails from domains or sites listed on a particular DNSBL. This can help reduce the amount of spam that users would otherwise receive. DNSBLs have also been used more recently as part of a spam scoring system, for example in SpamAssassin.


How do business sites get blacklisted?

There are several reasons why a business website may get blacklisted. This can happen if your server is relaying spam mail, if spam filter sites detect a high "bounce rate," if your mail servers are pumping out an unusually high volume of mail, if your emails are graphic and flash animation heavy, or if your email attachments contain malware.
