Yes that is possible!
At the moment you have to import a simple Excel file with fields.
Create a new sheet "mailreports" with cells = [First Name], [Last Name], [E-Mail], [Subject], [Region] and so on.
You can add cells how you like.
Save the Excel file and import that to your source Qlik App, important.
Note: the reporting script logic have to be insight of source Qlik App.
Now you have access to to data from the Excel file like the dimension [E-Mail] now you can Loop over [E-Mail] to send out your report or you can combine a data field like [Region] and loop over there so you can change the recipient per dynamic filter value?
In principle, this can be managed very easily via Excel file. You only need to import it and select the dimension after the import.
