Blacklist API use case

Every day, billions of emails are sent. Not thousands. Not millions. Billions! It’s hard for any software or system to automatically or programmatically detect if a message is spam or a genuine important email message from one person to another. So there are a lot of false positives, and there are companies that get blacklisted just because of a bad neighborhood.

You know what we are talking about, email blacklists are a real issue, and our Blacklist API helps you detect that issue whether it’s an IP address or a domain name. So if you are a hosting company with hundreds of IP addresses, or a email marketing company with thousands of them, our email blacklist API can tell you when an IP or a domain name gets blacklisted by one of the major RBL blacklists.
