How do I get my IP/domain removed from a blocklist?
Blocklists affect your email reputation and can impair the delivery of your messages. While there are many additional factors in email delivery, knowing if your IPs/domains are blocklisted is a critical aspect of email delivery.
Blocklists are private entities that can add or remove IPs/domains as they see fit. It can often be frustrating when trying to request removal, especially when the lists simply do not respond. Be aware that when requesting removal, you need to follow all of the instructions on the specific blocklist’s site and that you explain what actions you have taken to ensure your system is safe and secure. We recommend that you address the following aspects of your request for removal:
- Ensure you have included all of the information requested. If there is a form to fill out, make sure the information is thorough and accurate. If an email or general input box is used, be sure to read through any text on the page. Often, lists will request something specific and if it is not included, your request will be ignored.
- You must explain the actions you have taken to check your system. This should include actions such as virus scans, reviewing email logs, and using the Mxtoolbox SMTP Tool to check for an open relay. The more information you include about what you did to resolve the problem or check to ensure that your system is not compromised, the more likely your request will be successful.
- Be nice. MxToolbox has worked with many of these lists, as well as users who have tried various tactics with the people running them, and we have found that rude, aggressive, or threatening messages never work. You are either messaging an automated system that will not care or, in some cases, a person who will likely disregard your request due to hostile language.
- Be proactive about improving your email reputation and message delivery. If you repeat the same habits that caused your domain to be blocklisted, you run the risk of being listed again. Implementing DMARC is a major step toward blocklist avoidance. MxToolbox's Delivery Center also helps you maintain a healthy domain, so check to see how it can improve your business email.
