How do I close my MSN account so I don't keep receiving more emails at that email address?

create a new email address and stop using the other one. after a while it will close itself due to inactivity.

usually they close your account if they see that u haven't used it in a long time, let's say 2-3 months, my suggestion is just stop using it create another one and problem solved
