nopz moses is correct there is no option for blocking spam on your blackberry email account your best bet is to change over and use a email address from say google or yahoo instead
you can go to email settings on your device and get into the bis client site where you can add filters, or here is the link to do it from your computer, just choose the link for your carrier. If you have never done it from the computer, it will ask for a user name and password, if you dont have the user name and password, you can set that up as a new user, or you may need to call your provider for that information ( sometimes if the email was set up from your device, it will use your 10 digit mobil number as the user name with no ppassword, calling tech support they should have admin rites to thier bis page, where the can help you set that up.) from the site using the link you can set your filters.

That sucks, I wish I could block just a certain email that gets sent to me everyday

Is there a link in the email for you to unsubscribe to their mailing list? Or
go on their website and see if you can find a way to have them change
your email to an account that is not on your Blackberry?
