I have suddenly stopped getting my newsletters as well. I sent two emails via the "contact us" and "support" icons listed on the bottom left of this page and received emails a day or two later each time telling me the below:
This message was created automatically by mail delivery software.

I have verified that everything is still correct on my profile. Maybe someone will read this here and help. I enjoy the newsletters and miss them.
