Hello,The Campaign Classic + AEM integration is not deprecated but email components are as they were not complying with latest email best practices. See here: Best Practices for Email Templates This means email components need to be created as part of the implementation project.

This issue has been corrected since then. We are  not reproducing anymore.

This is indeed a limit in the current feature. Nesting loops is not supported and  it is quite difficult to build a comprehensive UI for that.Workarounds could be:- you can flatten the hierarchy by having a record for each combination of the 3 criterias.- or you can build the content in a static way...
