I'm reading up on a couple of the email variables, and I'm not understanding how to use the mktoHTML variable. I get the instructions, but it seems to be missing a crucial piece of information, or I'm being dense:
The Marketo explanation shows the metatag, and explains that it's boolean:
"Add Tracking Pixel"
It shows the token that I'd place somewhere on the template:
So far, that all makes sense. What I'm not understanding is... where do I put the actual html that one chooses whether to place.
So, in the example they give, where is the actual tracking pixel code, i.e. <img src="https://x.com/image.jpg"> etc. etc.
ha.. dang. Dumb question.. It pops up a window. I forgot I had to drag a new item over into the email template, before I could see it anywhere.
