I’m trying to track how many times an email blast has been opened. What I have done so far is embedding an image tag in the HTML email:
However, the problem I’m having is that this is only recorded as a visit to the website without any details that it’s from the email blast. pk_campaign isn’t working in this context. I’m not sure if it needs JS.
What’s the best way to achieve this without the use of JS? Is there a certain parameter I can append to the URL so I can record a custom variable without using JS?
