I'm purely speculating -- but I'm guessing it would fire only the one time, since it's using the email as an identifier. You might check with Litmus to be sure, but if you want each email to record differently, I'd make three unique codes.

Hi,
I tried the email script token, it seems the code only works if added just above the </body> tag, which is only possible if you email doesn't have any dynamic content.

As noted in the other thread, this is not true. It’s perfectly possible to inject a custom <img> tag via Email Script and also have dynamic content elsewhere.

Just adding the <img> tag will only give of open leaving out important metrics, If we add the litmus tracking in the module, Marketo parsed the HTML and stripped of all the litmus tracking keeping just the <img> tag which affects the tracking in litmus.
