I received the email that is being discussed here. The thing is, I don't subscribe to any emails in the settings on SO.

It seems like a bit of an oversight that a user who went out of their way to not get this kind of marketing emails is now receiving them.

I clicked the unsubscribe link in the email and it took me to my SO email settings, where as mentioned all the options are unchecked.

How can I unsubscribe from these emails?
