What Is An Email Blocklist Check and Why Does It Matter?
No one wants to be on a blocklist, especially a business running email marketing campaigns. If your company’s mail server appears on an email blocklist 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 blocklist 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 blocklisted. And spam blocklists are lists that you definitely don’t want to be on.
When it comes to blocklists 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 blocklist 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 blocklists.
The Importance of Email Blocklist Checks
So, how do you tell whether your IP address or domain name has popped up on an email blocklist maintained by Spamhaus or any other creator of spam blocking lists? Perform a blocklist check. This check will determine whether your IP address or domain name has landed in a blocklist database. If you find out that your IP address or domain name is, indeed, on a public or private email blocklist, then your entire email marketing campaign could be damaged. Showing up on a blocklist means email servers are judging whether your company’s emails should be sent to recipients or not.
Various tools are available to conduct blocklist checks. While your ISP should signal whether any of your IP addresses or domain names are on an email blocklist, 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 blocklist monitoring tool to see whether your company has shown up on a blocklist. If the tool does come across your IP address or domain name, then you can act fast to get that information removed from a blocklist.
