I've noticed that Triggered Sends in Marketing Cloud only allows you to select emails built within the Classic Content Builder, is there a way to get Content Builder emails available?
I have many emails which utilise Dynamic Content and also data from the Data Extensions using %%FIELD_NAME%%
tags, which from my understanding is not possible using the Classic Content Builder unless we use AMPScript.
If using Content Builder is not possible with Triggered Sends what would be the next best solution to sending emails to users when a new record is created in Salesforce custom object? Pushing the records into a Journey is possible but the most frequent I can have these emails sent would be an hour which is too long.
EDIT: Triggered sends are from Salesforce using Marketing Cloud Connect.
