When using Push Messages you can create a Custom Segment "Geofence = " and then select one of the Places. Push Messages cannot be fired immediately when someone enters a Place. Push Message message just work of the values that have been received in the past, but does not have a concept of a trigger. If you want to send a message when a user enters a Place/crosses a geofence you will need to work with In-App messages.
1. I understand the utility of in-app messaging with geofencing which is triggering messages when the user enters/exits the radius of the POI. But, what I am not being able to get is the utility of push with geo-fence.
2. With an analytics premium account and adobe mobile services, I can utilize geo-fencing with in-app messaging. Can geo-fencing be done with push as well ?
