ASP.Net/C# - Trap the button click event from html content

Question

Hi,

We have a C# windows appilcation that sends out emails to our customers. We want to put some buttons in the content of the mail and when the users click on the buttons, we want to send a reply to some address. We are facing the following problem in this task:
1. In the emails that the customers receive, we are not able to trap the button click event. How to do this? We want to write the code in the button click to send mails to an address. How do we capture the button click event in the mail content?

Thanks in advance
RS
