"How Can I Find Out If My Email Is Being Blocked?" - Blacklist Lookups
"How can I find out if my email is being blocked?" is a common, frustrating, and
perplexing question. Often people want to know whether their email server (the
computer from which their email is sent) is listed on a blacklist (sometimes known
as a "blocklist"), and that is a good place to start.
But how do you find out whether your email is being blocked by a blacklist or
blocklist?
ISIPP has compiled a list of places where you can go to look up to determine
whether your IP address or email sending domain are listed in any of the major
blacklists. While we don't endorse or promise the accuracy of any of these
lists, these are some of the lists to which we ourselves may refer in
troubleshooting a particular deliverability problem.
