Have a simple GEV Service that sends an email - input FC > Spatial Filter w/ Geofence > Email.
All works well, with the only hitch being that it sends an email every few seconds, and we really only need the initial email.
Not able to figure out if/where you can modify a component of the service to limit it to one email. I've also gotten this to work with an Incident Detector w/ Geofence, but had the same issue w/ multiple emails being sent.
Thanks -
