@Madison Thompson asked if anyone has used this and if it could be a merge field in MCAE. I don't know the answer to that, but I don't see why it couldn't.

I'm sorry, but I am not a MCAE user. It's using HTML and goes into a rich text field so... I would research how to use merge fields with HTML in account engagement.
