Tracking fully dynamic email delivery?

[#1]

Hi there,

Trying to send out an email delivery with a conditional statement because there are 22 different versions based on certain qualifications. We would love to track activity (opens, clicks, etc) by version but can't seem to find a way to clearly differentiate one version from the other. We tried to pull in the subject line to track it that way since each version has their own (which is also being pulled in dynamically). But, whenever we pull that into the tracking section it only shows the conditional statement. Has anyone ever encountered this problem or have any ideas?

Thank you!!

Here's an example for one of the versions.

<script>

document.write("<img height='1' width='1' alt='' src='http://t1.links.eftours.com/r/"

+  Math.random().toString() + "?tagid=Open_TO01'/>");

</script>

<noscript><img height='1' width='1' alt='' src='http://t1.links.eftours.com/r/?tagid=Open_TO01'/>
