No more techmails?

Okay, for lack of finding any better place to post this…

Why have my techmails stopped being delivered?

I have subscribed, unsubscribed, and re-subscribed to various techmails but they never arrive. I do get the confirmation email that says I’ve changed my subscriptions and it shows which ones I should be getting.

Has anyone else had this problem? This isn’t a huge deal since I can always sign-on here and check out the latest stories, but I am curious why I’m not getting the emails anymore..
