Not getting email notifications

I just realized today that I have not been getting normal LT email notifications. Last one received was May 4th.

I checked my profile settings >Account Settings. I'm still checked marked to receive emails for

Email comments and notifications to you
Receive the monthly "State of the Thing" email
Receive emails in HTML format

Nothing from LT in my spam folder. I also checked that email was working fine by sending an email to it.

Any ideas?
