For some reason, GMail's filters are handling Sheldon like spam. (Boo, GMail!) To fix that, just do this:
Go into your GMail account, click on "Contacts" (should be on the lower-left side of the screen), and add this e-mail address as one of your "new" contacts:
do_not_reply@sheldoncomics.com
Even Google can be lame, sometimes...but this should fix it.
Could it be that the "report spam" button is right next to the delete button in the Gmail interface? If enough users push the wrong one after reading, I could see why the mail-outs get marked. Not saying it's right, I'm just sayin' is all.

True, if enough people mark the mail as spam, it will be flagged as spam across the system.
Anyone who sees the mail in their Spam folder, be sure to click "Not Spam" on it. If enough people do that, it might be redeemed.
