It is indeed a problem. About a month ago, I was emailing back an forth with members of the GL internet committee. You may have noticed when you signed up for emails on the GL website, there was a mention specifically about issues with Verizon...which happens to be my provider.

I've spoken with a few people at Verizon however; its difficult to get past the Tier 1 folks (mainly in the Philippines) that answer the service number.
Unfortunately, as long as the GL utilizes Virtbiz to host their email propogation, the problem will continue. I've read a few blogs after finding out who they were and have seen other notations out on the Net that it is a recurring problem concerning this particular provider. If the GL switch providers, this could rectify the situation. Of course it would take a bit of research to ensure they just don't move from one problematic provider to another.
Bottom line, if you wish to receive communications from the GL via email, you will have to create a web account with Yahoo, MSN, etc, etc.
I would like to receive the emails from them however; not enough to complicate my digital life by creating an account simply for receiving emails from a single source.
