Hi Eric,
I have created a video to answer you, explaining the current implementation that I am doing and additional things that I am planning - usually people don’t have 17 minutes to watch / read an answer, I tried to be brief, but I did not rehearse and sometimes was hard to find the words. here is a guide of what I talked:
00:00 - [Intro & Demo]
03:05 - [Overview of the Implementation]
03:39 - [Mautic Tracking Pixel]
5:05 - [About Tag Manager]
12:00 - [Google Analytics with Mautic]
