Option for client to Opt-out from Specific email notifications

We recently enabled emails to notify clients of expiring reward points. All email communications should have a way to opt-out of emails, this is a must for any online store.

Cart.com only provides opt-out options for product notifications by using:

##STOREURL##/store/remove.aspx?email=##NOTIFICATIONEMAIL##&nid=##NOTIFICATIONID##

Include opt-out options for ALL the marketing emails such as "Reward Points", "Request for Reviews", etc
