I want to use google analytics to track my e-mail opennings. It should be quite easy, there is a relative good documentation on it. It is a simple URL with parameters inside a <img>
tag. My problem is that one of the parameters has to contain a random number.
Here is an URL example:
<img src="http://www.google-analytics.com/collect?v=1&tid=UA-12345678-1&cid=CLIENT_ID_NUMBER&t=event&ec=email&ea=open&el=recipient_id&cs=newsletter&cm=email&cn=Campaign_Name />
The CLIENT_ID_NUMBER must be a random number for each e-mail. How do I change it dynamically using only HTML, since e-mails do not support javascript?
Thank You Very Much
