What Is An Email Blacklist Check and Why Does It Matter?

No one wants to be on a blacklist, especially a business running email marketing campaigns. If your company’s mail server appears on an email blacklist or your email goes to a spam trap, it could put your email marketing efforts in the red. Why? Because your emails could wind up getting throttled after blacklist service providers have flagged your IP address or domain name for possibly sending spam.


The Search for Spam

At all times of the day, any number of organizations are scouring the internet in an effort to combat spam. These organizations collect details associated with suspected spammers and dump them into spam databases. If your IP address or domain name is listed in one of the databases, then you’ve been blacklisted. And spam blacklists are lists that you definitely don’t want to be on.

When it comes to blacklists to worry about, Spamhaus is at the top of the list. As of May 2018, the nonprofit organization was protecting nearly 2.7 billion email inboxes around the world. Its real-time threat and reputation lists block the majority of spam and malware sent via email. Spamhaus’s blacklist data is used by many internet service providers, email service providers, companies, universities, government agencies, and military networks. Globally, Spamhaus maintains a network of more than 80 public DNS servers that run billions of daily queries against DNS-based blacklists.


The Importance of Email Blacklist Checks

So, how do you tell whether your IP address or domain name has popped up on an email blacklist maintained by Spamhaus or any other creator of spam blocking lists? Perform a blacklist check. This check will determine whether your IP address or domain name has landed in a blacklist database. If you find out that your IP address or domain name is, indeed, on a public or private email blacklist, then your entire email marketing campaign could be damaged. Showing up on a blacklist means email servers are judging whether your company’s emails should be sent to recipients or not.

Various tools are available to conduct blacklist checks. While your ISP should signal whether any of your IP addresses or domain names are on an email blacklist, things sometimes slip through the cracks. For instance, your email marketing messages could have mistakenly been marked as spam messages. That’s why it’s smart to use a blacklist monitoring tool to see whether your company has shown up on a blacklist. If the tool does come across your IP address or domain name, then you can act fast to get that information removed from a blacklist.
