Is Your Website on a Blacklist? Check Now for Free
Being on a website blacklist can severely harm your site's reputation, block your emails from being delivered, and cause search engines to display warnings to your visitors. Our free Website Blacklist Checker instantly scans your domain against the most common DNS-based blacklists to see if you have been flagged for spam or malicious activity.
How to Use the Blacklist Checker
- Enter Your Domain or IP: Type the website URL or server IP address you want to check.
- Run the Scan: Click the "Check Blacklist" button to begin the scan.
- Review Your Status: Our tool will show you whether your domain is listed as "OK" or "BLACKLISTED" across dozens of databases.
Why is Checking for Blacklists Important?
If your website is blacklisted:
- Your emails may be marked as spam and never reach your customers' inboxes.
- Your website traffic can drop significantly if browsers show security warnings.
- Your brand's credibility and trustworthiness can be damaged.
Regularly checking your status is a critical step in maintaining a healthy online presence.
