Getting Forum/Blog Email Notifications

I don't really like them. My inbox becomes full of Junk and I end missing important messages consequently. You can usually "unsubscribe" from email notifications in the message. Generally speaking, there should be a link at the bottom where if you click, you won't receive any further correspondence.
I don't mind them if it's once in awhile but if they keep sending emails then it gets annoying. Same for any businesses that I sign up for their emails, if I get too many of them then I just unsubscribe. Sometimes its good knowing that they have a sale on when they send that email.
