Setting an Email Subject Label based on a USERSETTING

[Daisy_Ramirez]

We have a client using several apps and need to apply a label to the subject line of emails generating from key apps so they know if the email came from a TEST app vs. their LIVE app.

I’m placing the following expression in USERSETTINGS() to place it into the subject line but I’m having trouble with the syntax. Can someone assist ?

IF(CONTEXT(AppName)=“TST_USA_Receiving-539632”,"-TEST RECEIVING APP","")
