First, check spam. They check your settings. If you are still subscribed in your settings, but don't get the newsletters, it means that you unsubscribed at some point. I think that we can re-add your email, but it takes some doing, since it's unethical to do so without having some proof that we can show that you wish to received newsletters again.
Hitting the "unsubscribe" button on any legit site is the nuclear option, btw. And for non-legit sites, it's completely useless anyway, so in general, I would advise against using that button, ever, and to just go to your settings to change things around.
