You may have unchecked the selections that allow us to send you mail.  You can check by going to your Account and then selecting Newsletter Subscriptions.

If this is not the case, then the emails may be going into spam.  This happens frequently with corporate email accounts.  You may wish to switch to a personal account in this case.
