Greg's company couldn't send mails anymore. After some research, he discovered they had landed on multiple blacklists. So he asked the blacklist providers to remove them from those blacklists. But one day later, they where back on again. The longer it takes to clean this mess, the worse it gets.
Greg shares his story with us, explains how it happens, and gives us valuable information on how to prevent this problem from happening.
