Hi everyone,
I'll add to this, that this option is possible to select on 3 different scopes:
1. Global - on mail settings, where system wide default mail template is defined. -> https://docs.webcon.com/docs/2024R1/Studio/SystemSettings/GlobalParams/EmailConfig/GlobalTempl
2. Process e-mail templates - in each process. -> https://docs.webcon.com/docs/2024R1/Studio/Process/EmailNotifications/Templates_General
3. Inside of an action 'Send configurable e-mail' configuration. -> https://docs.webcon.com/docs/2024R1/Studio/Action/Notifications/Action_CustomEmailSen1#message-content
Of course it is possible to override that behavior on specific actions, as Jack already showed :)
This knowledge comes in handy, when you are also sending 'Standard email' when task is created. -> https://docs.webcon.com/docs/2024R1/Studio/Workflow/Step/Path/Action_StepEditPathsCreatingTask
By changing Global / Process standard email (which might be also customized) this will apply to those 'Standard emails' too, not only configurable ones.
