My question is in the title: Is it possible to send an email from external file datas that I'm importing in the workflow by a file loader activity ?
I tryed to configure a new Target mapping but without sucess ?
If you have some tips about it !
The second Activity in the Workflow where Audience is being saved, what was the option selected and did the Audience already exist within ACS Instance.
To answer your first question, Is that significate that I need to save these contacts in my application (in nmsRecipient) -> You need to define a one time Audience.
Therafter keep updating it everytime a new file is uploaded. Then Save the Audience as per correct option, query it/Read Audience to target Delivery.
