Do your action means Actions in RF? (RF Admin->Config App->Actions)
If that is the case, you can fire the email when a new action when a specified action new created.
Create a workflow rules with proper workflow actions for Incident History object:
BMCServiceDesk__actionId__c = "Name of action"

Daniel, I found a way to get this done without making it too complex. I have one workflow to send an email if two fields are selected and then I created a second workflow that clears one of the two required fields. It's not pretty, but it will get the job done.
