To unsubscribe to the newsletter, go to your User CP (at the very top, next to Home) > Settings & Options > Edit Options > Messaging & Notification > Newsletters Settings: click on the link provided there which will take you to Email Preference Center
(it should have your email on it).
It should look like this:
I did this for you already but looking at your email in your account, it ends with .come - is it supposed to be like that or .com?
If it's supposed to be .com, please confirm so we can correct this and the newsletter settings. I unchecked those options you see there (weekly newsletter, breaking news, and special offers/eblasts) and submitted for you.
You should not be seeing any more of these. Let us know if you need further help.
