Hi there, I have a newsletter. I send it to 5,000 people and I want to know who open the mail and who click on it. So I undersatnd that it's not a problem to know who clicked but How can I know who open it. I thought to put an img that is taken from my server and then when the user open the mail he "call" my server and take the pic. But how can I know what is the specific ID that do that? Or maybe u have another idea?
Then in count_me.asp you call the sql database and do what you want cause you know the userid of the person viewing the email by the request.querystring("id") then at the end of the count_me.asp do a response.redirect("space.gif") or another image so something shows up.
