Enter your IP address or domain name in the search field, then click "Check Blacklists". The tool will scan multiple blacklist databases and display results showing whether your IP/domain is clean or listed on any blacklists.

What are the Benefits of Blacklist Checker Tool?

The tool helps protect your email deliverability, maintain domain reputation, identify security issues, prevent spam classification, and quickly detect if your server has been compromised or is being used for malicious activities.

What Should You Pay Attention to When Using the Tool?

If you find your IP/domain is blacklisted, identify and fix the root cause (spam, malware, compromised accounts), then request delisting from each blacklist. Regular monitoring is recommended, especially for mail servers. Some blacklists may have false positives.
