Domain Blacklist Check - Do you want to protect your website's integrity? Verify your domain against various blacklists to ensure it hasn't been flagged for suspicious or malicious activities. Regularly monitor your domain's blacklist status, as it helps to avoid potential security breaches while maintaining a trusted online presence.
How Does Our Blacklist Checker Works?
It is designed to be the ultimate solution for real-time checking IP, domain, and email blacklist status. Here’s how you can use it even if you do not have any technical expertise:
- Enter Details
Specify the IP address, domain name, or email address you want to check in the updated blacklist databases. Enter only a single query in one attempt.
- Start Scanning
Click on “Check in Blacklists” to run our blacklist checker. It will retrieve the associated IP, which you’ll need to tap to proceed and get a result.
- Check Blacklists
It will display all the blacklists, highlighting whether the domain, IP, or email is enlisted. “Yes” indicates that it is blacklisted, whereas “No” indicates that it is not blacklisted.
If you find your resource enlisted in any blacklist database, click “details” to understand why it is blacklisted.
Note: We do not manage, run, or have any direct affiliation with any blacklist. We only provide a single platform to check a domain, IP, or email server status on third-party blacklists. We do not recommend using any specific blacklist or condone blacklists that require payment for removal. Including such blacklists in our tool is for completeness and should not support that blacklist's usage.
Email Delivery Process and Spam Filtering Mechanisms Explained
The process is straightforward:
- When you send an email from marketing@xyz.com to user Mike, his mail server will identify and convert the sender's IP address into the corresponding domain name.
- The mail server then checks the domain and the sender's IP address against a blacklist database containing known spam sources.
- If the IP or domain is found on the blacklist, your email will likely be diverted to Mike's spam/junk mail folder without being scanned.
- If the IP or domain is already listed as a “repetitive spam sender”, the ISP's spam filters will reject the message entirely, preventing it from reaching Mike's spam folder.
