Create notifications not only based on segments, but also based on time, new deals, new posts. Usage for example: Team zoom every Monday at 1pm, create notification to pop every Monday at 12:30. When new deal/offer comes out, send notification. Instant push notifications, or timed to 5 minutes ahead if urgent message needs to be sent to a user group or all users. Plenty of ways to play with it, pretty important in my opinion as most emails and texts gets 'swallowed' whereas push notifications stands out.
