Domain Reputation Checker

Your domain is your online identity. When it gets blacklisted, your emails stop reaching people, your website traffic drops, and your reputation takes a hit. This free domain reputation checker scans your domain against 15+ major security and spam blacklists in seconds and gives you a clear reputation score.

No login needed. No signup. Just enter your domain and get results.

What this tool does

The domain reputation checker tool scans your website’s domain name against a wide range of DNS-based blacklists, also known as DNSBLs. These are databases maintained by security organizations worldwide to track domains linked to spam, phishing, malware, and other threats.

You get a reputation score from 0 to 100. You also get a letter grade from A+ to F. And you see exactly which blacklists flagged your domain and which ones show it as clean.

This is different from checking your IP address. IP blacklisting affects your mail server. Domain blacklisting targets your website name itself. Both matter, and both need separate checks. You can check your mail server separately using our IP Blacklist Checker.

Tool Features

• Scans 15+ major domain blacklists including Spamhaus DBL, SURBL, URIBL, SORBS and Google Safe Browsing
• Shows a reputation score from 0 to 100 with a letter grade
• Displays your domain’s resolved IP address and MX record count
• Highlights each blacklist result individually so you know exactly where the problem is
• Works for any domain, no login required
• Results load in under 30 seconds
• Fully free with no usage limits

How to Use the Domain Reputation Checker

Step 1. Type your domain name in the search box. You can type it as example.com, www.example.com, or paste the full URL with https. The tool cleans it automatically.

Step 2. Click the “Check Domain” button.

Step 3. Wait about 20 to 30 seconds while the tool scans your domain across all blacklists.

Step 4. Review your reputation score and grade at the top. A score above 90 means your domain is in good shape. Below 80 means there are issues to fix.

Step 5. Scroll through the detailed results table to see which specific blacklists flagged your domain. Use the blacklist guide below the results to understand what each listing means and how serious it is.

Do you need this Domain Reputation Checker tool

Lets understand with example how this tool could be useful to you. Lets say you are a business who owner notices that your newsletter emails have a 2% open rate this week, down from 25% last week. You used this tool to check your domain and found it listed on Spamhaus DBL. A hacker had used your site to send spam. You now fix the issue, request delisting, and email delivery recovers within 48 hours.

Second example, let say you are a freelancer who buys an expired domain for a new project. Before building on it, you ran a domain reputation check and found the domain has a URIBL Black listing from its previous owner. You choose a different domain and save months of future headaches.

Third Example, Lets say you are a web developer who gets a call from a client saying Chrome is showing a security warning on their site. Now you checked the domain and confirms a Google Safe Browsing listing caused by malware injected through an outdated plugin. You clean the site, remove the malware, and submit a reconsideration request.

Basically this tool can be used by anyone who is using a domain which is like everyone in todays world.

What to do if your domain is blacklisted

First, find out why. Visit the blacklist’s website, search your domain, and read why it was flagged.

Fix the root cause before requesting removal. Remove malware. Delete phishing pages. Secure any compromised accounts. Update outdated software. A blacklist will not remove you if the problem still exists.

Then submit a removal request through the official process for each blacklist. Some remove listings automatically once the issue clears. Others require you to fill out a form. Most listings clear within 24 to 72 hours after you fix the problem.

Going forward, keep your software updated, use strong passwords, enable two-factor authentication on your hosting and domain registrar accounts, and run monthly security scans. Check your domain reputation checker results weekly so problems get caught early.

Frequently Asked Questions

What is a domain reputation checker?
It is a tool that scans your domain name against spam, phishing, and malware blacklists to check if your website has been flagged by security organizations.

How is domain blacklisting different from IP blacklisting?
Domain blacklisting targets your website name and affects SEO, browser trust, and email reputation. IP blacklisting targets your server address and mainly affects your mail server’s ability to send email. Both need separate checks.

My emails are landing in spam. Can this tool help?
Yes. Run a domain blacklist check first to see if your domain is listed on any spam databases like Spamhaus DBL, SURBL, or URIBL. If it is, that is likely causing your delivery problems.

How often should I check my domain?
Once a week is a good habit for active business websites. Check immediately if you notice traffic drops, browser warnings, or email delivery problems.

Can a new domain be blacklisted?
Yes. If you bought an expired or previously owned domain, it may carry old blacklist listings from its previous owner. Always check a domain before building on it.

How long does it take to get removed from a blacklist?
Most blacklists remove listings within 24 to 72 hours after the underlying problem is fixed and a removal request is submitted. Some remove automatically. Others need a manual request.

Does being blacklisted affect my Google rankings?
A Google Safe Browsing listing directly removes pages from search results. Other blacklists do not affect Google rankings directly but signal poor domain health which can have indirect SEO impact.

What causes a domain to get blacklisted?
The most common causes are malware on your website, phishing pages, outbound spam campaigns, hacked accounts sending spam, and compromised contact forms being used to send bulk messages.

My domain shows clean on all blacklists but emails still go to spam. Why?
Blacklisting is one of many factors affecting email delivery. Other causes include missing SPF, DKIM, and DMARC records, low engagement rates, poor email content, or a shared IP with a bad reputation. Use a dedicated email tool to check those factors separately.
