Get real-time blacklist monitoring

An email blacklist is a collection of email addresses that are known spammers, spoofers, and overall bad actors. Internet service providers work closely with blacklist services to know which email senders are trustworthy and which senders pose a risk to the public and their private information.

An IP blacklist is a type of email blacklist. Your email domain, IP address, or both may be what’s added to an email blacklist. If either your company domain or IP address ends up on a blacklist, you need to take action immediately to protect your sender reputation.

Blacklist monitoring works by providing the service with the domain or IP information you want to monitor. Depending on the blacklist monitor, you can actively supervise your domain, subdomain, and different types of IP addresses, including IPv4 and IPv6. The email blacklist checker in our service then actively compares this data against its known list of blacklist providers and automatically alerts you if your domain or IP is detected on any list.

Yes. Removing your email domain or IP from an email blacklist is possible by contacting the blacklist provider. Many blacklist providers have websites that allow you to look up your domain and IP and learn what infraction led to the blacklisting. After you take action to resolve the problem, submit evidence to the blacklist service that the problem is resolved, and you will be removed from the list. Please note that this may not be true for email domains with repeated infractions and multiple blacklistings. If there is substantial damage to your sender reputation, you should show considerable effort to improve your email-sending habits before you can be removed.
