Blacklist Checker: Scan Your Domain, Email, or IP Address
Keep your online presence clean and trusted. Our Blacklist Checker uses up-to-date data and advanced detection to determine whether your IP address, domain, or email address appears in major blocklist databases. It helps you spot suspicious activity early and take quick steps to protect your website, emails, and overall reputation.
IP Blacklist Check
Is your website or server acting slowly, blocked, or unreliable? Run an IP blacklist scan to see if your IP address is listed in spam or security databases. Catching an IP listing early helps you fix issues faster and keep your services running smoothly.
Email Blacklist Check
Are your emails landing in spam—or not arriving at all? Use the email blacklist check to test your email address against multiple blacklists. It helps you improve deliverability, prevent future blocks, and protect your sender reputation.
Domain Blacklist Check
Want to keep your website safe and trusted? Use the domain blacklist scan to confirm your domain hasn’t been flagged for malware, phishing, or suspicious behavior. Regular checks reduce risk, support better trust, and help you maintain a strong online presence.
How Our Blacklist Checker Works
Our Blacklist Checker makes it easy to verify the blacklist status of an IP address, domain, or email in real time. The tool is built for everyone, so you can run a scan and understand the results even without technical experience.
Enter Your Details
Type one item only per scan: an IP address, domain name, or email address. It helps the tool check accurately and return clear results.
Start the Scan
Click “Check in Blacklists” to begin. The tool will search relevant databases and, when needed, show the related IP so you can continue the scan and view the final report.
Review the Results
You’ll see a list of blacklist databases with a simple status:
- Yes = the IP, domain, or email is blacklisted
- No = it is not blacklisted
Open Details
If any database flags your entry, click “Details” to learn the possible reason for the listing and what it may affect.
Note: UrwaTools does not operate or control any blacklist databases. This tool only checks your IP address, domain name, or email address against third-party blacklists and displays the results in one place. We don’t promote any specific blacklist, and we do not support pay-to-remove blacklist services.
How Email Delivery and Spam Filters Work
Email filtering follows a simple flow. Here’s what typically happens when you send an email:
- You send an email from [email protected] to Mike.
- Mike’s mail server identifies the sender’s IP address and may also map it to the related domain.
- The server checks the sending IP and domain against blacklist databases that track known spam and suspicious sources.
- If the IP or domain is listed, the message is often treated as risky and may be moved to Spam/Junk or limited before deeper checks.
- If the sender is marked as a repeat spam source, many providers will block the email completely so that it won’t reach Mike’s inbox—or even his spam folder.
