An IP Block List is a database of IP addresses that have been associated with spam, or unwelcome emails. As an email marketer, landing on one of these lists isn’t a place you want to be. Being blacklisted can lead to communications barriers, a decrease in email deliverability and, ultimately, a loss of trust among your customers.

While it is impossible to completely avoid a dreaded blacklisting, there are ways to mitigate the risk of ending up on one. The most effective way to reduce the likelihood of being added to an IP blocklist is by employing a device intelligence solution, which uses data points like email engagement and web traffic to accurately identify a subscriber’s unique device. This prevents suspicious devices from being able to access your website or sign up for your email list.

However, even the best device intelligence tools can fall prey to false positives if an email sender is consistently sending poor-quality content or spamming their subscribers. To avoid this, it’s important to keep an eye on the quality of your email campaigns and ensure your email bounce rate doesn’t exceed 8%. Having a high bounce rate can signal to your subscribers that your content is not relevant or valuable, which could prompt them to mark your messages as spam and potentially get you blocklisted.
