I was getting the email updates, but then it just quit, all of a sudden. After a little while, I got a PM from AnandTech Moderator, stating that my ISP was kicking back all of their messages as spam. My ISP never told me they were going to do this, nor did they ever admit filtering spam, nor do they allow me to change that option (needless to say, I'm kind of upset, and am thinking of switching to another ISP). In the end, I had to get a free email account that isn't blocked by AnandTech to get my subscription messages.
Cliff's notes: check to see if your ISP filters "spam"
