New Email Builder and MSI

I couldn’t find it either and was told by someone the feature doesn’t exist. Not sure if it is coming soon or not. I just set up a Marketo trigger campaign so people with MSI can Add to Marketo campaign and then it fires off the email. Maybe someone else knows more. I’ve only been back in the system for a few months after 3 years out. 

Based on a recent conversation with Adobe Support, I can confirm that this is currently a limitation of the New Email Designer. Emails created using the New Email Designer cannot currently be published to Marketo Sales Insight (MSI).

Support also indicated that MSI publishing support for the New Email Designer is planned for a future release.

For now, if MSI publishing is required, you'll need to use the classic email editor or implement an alternative workflow, such as a Smart Campaign-triggered send.
