We want to implement email tracking so we know which of our users is actually reading our emails. One of our ideas to do this is to place an invisible image pixel in our emails so we can detect if an e-mail's been opened. We are using IIS.
Is there a way to figure out when an image is accessed?
For example, we would include something like this in the email:
https://www.mycompany.com/invisibleImagePixel.png?UserId=45613237
But how do we intercept this GET in IIS?
