We are sorry you are not receiving emails from Java Momma.
Many e-mail and Internet companies are now using programs to block unwanted e-mail, often called spam, there may be some filtering happening on your server's side that checks the emails. There are cases when these filters click the links inside in order to check for spam and phish, and possibly your provider has a server that does these kind of checks. Unfortunately, there isn't much investigation to be done on our side as this would be on the provider server side.
Sometimes, however, these programs block e-mail you actually want to get.
To make sure you get your emails head on over to blog and read this article about whitelisting Java Momma!
