Siebel CTD Accept / Reject

Hi All,

  We have recently implemented CM suite to one of our customer, Now we have a requirement to do a Accept/ Reject kind of functionality..

Case :

When ever marketing team sends out emails to customer about the product, they would like to know if the customer is interested in the product by doing a accept / reject kind of functionality.

i.e when ever the customer recieves the mail , he would read thru the content and say accept or reject, we are planning to leverage Siebel CTD functionality such as Subscribe / Unsubscribe.

Any ideas on how to approach it in a better way ...
