C#, VB6, Email

Hi All

I have a CMS program that is written in VB6 that manages member databases for clubs etc.

Given the prevalence for Email trackers ie. Respond when someone opens your email or clicks on a link. I was looking to build this type of tracking into my app. This is not a SPAM program as batch emails are sent to only members in DB who are opted in for such contact.

I am happy to build this in either VB6 or Interop with C#.

Any ideas where I start with this, haven't found anything handy online.

1. Create a GenericHandler that renders an image of 1x1 pixels (blank content)
2. This handler will receive a QueryString variable, this variable will contain the unique id for your e-mail (I propose the use of GUID)
3. Each time your GenericHandler receives a request, it takes the query string variable and then you can update your database recording the activity.
4. In your e-mails, send an image element that points to your GenericHandler with the unique query string variable

Hi jorge_toriz:

Ok, I get the idea of what you are suggesting, but can't get my head around how an image can be triggered to send a response to Handler on email being opened.

Can you point me in the direction of some sample code on this subject?
Thanks
