Why Check If Your Domain is Blacklisted?
- Email Deliverability: Blacklisted domains often get blocked by email services like Gmail, Outlook, and Yahoo.

- Monitor Reputation: Keep your domain clean to ensure a good sender and server reputation.
How the Domain Blacklist Checker Works
Enter your domain name (e.g., yoursite.com) and click "Check." The tool scans multiple DNSBLs, including SORBS, Spamhaus, SURBL, UCEPROTECT, and more. You'll get a full report on whether your domain appears in any of the blacklists and which ones.
What to Do If Your Domain is Blacklisted
If your domain appears on any blacklist, you’ll need to investigate the reason—whether it’s due to spam emails, malicious content, or compromised security. Most blacklists offer a process to request delisting. Our tool helps you catch the problem early and act before it affects your traffic or reputation.
