In FME Server 2019 beta, triggers and actions are individual objects with a single action. Therefore If you had 100 automations, and 30 automations that send an email utilising the same configuration, you actaully have 30 seperate email actions. If something changed in that email configuration, you would need to find the 30 locations and change this in each one. If would be great if there was a parent template that held connection information, that update child objects?
N.B. Currently, you could utilise the "notify topic" option, but then you are jumping back to notifications (publishers/topic/subscribers)
