'Publish for Subscription' in OTBI Agent

Content

Hi, can anyone point me to any information on how to best utilise this feature within OTBI agents. Ideally I am looking to establish a way to set an agent to notify recipients when an analysis has been run and data produced but not physically send it as an attachment (due to the inability to password protect the file).  I wondered if the Subscription functionality is the way to do this but I haven't really used it before so am a little unsure of what it's meant to do

Apologies if this is documented somewhere obvious, I just can't seem to find anything.
