Hey @mahrmm one quick note as I looked at this, too. You can add custom object personalization only in automated emails currently, not regular emails. In case that affects what you’re doing.
I hope this is still open.
Im struggling with having both deal tokens and custom object tokens in the same mail. It seems that the deal based flow does not include the associated object properties. Do any of you know if its possible?
I would highly recommend you to please post this idea at our ideas forum (here).
