I will be interested to see replies to this. I am new to server as well, and would also like to know if this is an option. If the data is stored on each user in your data source,it would make it easy to compile your lists. If you don't handle the data warehouse yourself, you might request this from your IT folks.
Automated email functionality would be very helpful in a lot of cases where I'm at--for instance, I'd like to have emails automatically sent to parents of students when absences or tardies reach a certain level for a student. That would make someone's life much easier.
I've created email distribution lists and add/remove users accordingly.
Very unfortunately the views in the Tableau Postgre db are VERY limiting I don't see any email address field in it.
