Stop Spam Email

I receive a lot of junk emails in my inbox, that I wish to stop receiving . Also, for example last year I bought some tickets from stubhub and to this day I still get emails such as shows coming up, and every time I register from something I uncheck or check that little box saying that I do not wish to receive emails from offers, etc.

i keep getting 100’s of junk emails for penis enlargement pills from all over the world how do i stop this and how do they get my email address?

I’m getting more than 200 junk emails everyday. I need to take care of this problem immediately. I tried spaming and unsubscribing. It’s not working! This should not be happening.

I don’t want all these junk emails on spam, would like to have them stopped.
