Newsletters and other mailings from LDW don't get sent out very often, since we don't like to create spam. We know that there are a number of email providers and ISPs that block email from LDW and/or put them in spam/junk/bulk folders. That's just the reality of commercial email these days. Adding ldw.com to your 'white list' can help with that situation.
Also, we maintain separate mailing lists for different purposes. There is a difference between signing up for the newsletter and signing up for specific game notifications on the
Previews Page. If you want to make sure that you're notified of the release of the new Virtual Villagers game, you should sign up on the Previews Page. When you sign up for a particular mailing list, you should receive future mailings, but not mailings that have already been sent out.
