Hi Kevin,
Mike is right. All you're gonna do is generate a small <form> in your Emails HTM section. The "action" for the form will be a URL of your site. Getting the URL right is important, so something like;
http://www.yoursite.com/response?accept=yes&user=lkhjfgsld8945Obviously each email you send out has a unique "user" field whatever that is. Typically it's the unique id of the record in the database.
In your procedure, called Response, you can use p_web.GetValue('accept') and so on.
But wait, there's more.
Many email clients no longer allow a Button in an Html email. In other words this approach no longer works. You are allowed a link though, so instead of a <form> with buttons, you use a link.
Cheers
Bruce
