What is IP Blacklist?

An IP blacklist is a database of IP addresses flagged for sending spam or malicious emails. When your IP is blacklisted, your emails may land in spam folders or get blocked entirely. This can damage your sender reputation and marketing performance. With our Email Blacklist Checker, you can quickly find out if your sending IP is listed on major blacklists—helping you take action and maintain strong email deliverability.


How does an ExactVerify Domain Blacklist Checker Work?

Our Domain Blacklist Checker scans your domain or IP against over 100 trusted real-time blacklist databases used by email providers to filter spam. When you perform a Domain Blacklist Lookup, Our system instantly checks if your domain appears on any email blacklist, helping you identify issues that could harm your email deliverability. The tool provides a detailed report highlighting which blacklists—if any—have flagged your domain. This lets you take quick action to delist and restore your sender reputation. It's fast, accurate and essential for protecting your email campaigns from unnecessary bounce rates and spam folder placement.


Why is my IP Address Blacklisted

Your IP address may be blacklisted if it's been associated with sending spam, malicious content, or violating email best practices. This often happens when you're using shared servers, outdated email lists, or running campaigns without proper Bulk Email Validation. Being on a blacklist can harm your email deliverability and reputation. With our IP Blacklist Checker, you can easily identify if your IP is listed on major blacklists. You can also check domain blacklist status to ensure both your IP and domain are clean—giving your emails the best chance to reach inboxes, not spam folders.


How to Remove my IP Address from a Blacklist

If your IP address has been blacklisted, start by using an IP Blacklist Lookup tool like ExactVerify to identify which blacklist has flagged it. Blacklisting typically occurs due to spam complaints, compromised servers, or sending to invalid email addresses. After identifying the issue, clean up your email lists with a reliable Email Verification Tool, secure your mail server and follow best practices.

Once the cause is resolved, go to the blacklist provider’s website to submit a removal request or follow their delisting guidelines. Some blacklists automatically remove IPs after a short period. For continued protection, use a Domain Blacklist Checker to monitor your domain’s status and avoid future listings. With ExactVerify, you can perform regular blacklist checks and maintain a strong sender reputation—ensuring your emails reach inboxes and not spam folders.

Frequently Asked Questions

After scanning, if your IP or domain appears on any blacklist, ExactVerify provides direct links to the relevant blacklist databases. To request removal, follow the delisting instructions provided by each blacklist. Before doing so, review your sending practices, resolve any spam-related issues, and ensure proper email authentication (SPF, DKIM, and DMARC) to prevent future listings.

Delisting time varies by blacklist. Some allow automatic removal within 24–48 hours once the issue is resolved, while others require manual review, which can take several days. To speed up the process, address the root cause of blacklisting—such as spam complaints or poor list hygiene—and ensure proper email authentication (SPF, DKIM, DMARC) before submitting a delisting request.

Being on a small or less-known blacklist can still impact your email deliverability, server reputation, or access to certain services. While major blacklists carry more weight, even obscure listings may signal underlying security issues (e.g., spam, malware) that could escalate if ignored. Use ExactVerify to monitor all listings—big or small—and take prompt action to delist and secure your IP.

We recommend checking your IP at least thrice a week, especially if you're sending bulk or automated emails regularly. Frequent checks help catch blacklisting early—before it impacts your inbox placement. It’s also wise to scan immediately after large campaigns, deliverability drops or unexpected bounce spikes.
