Sponsored push notification

Push is the scarcest and most intrusive inventory in the app, which is exactly why it's valuable and exactly why it needs rationing. A well-timed push — "Live demo at stand B40 in 15 minutes" — can visibly move people across a hall, and that measurable footfall effect is a strong selling point. But every notification spends a little of the audience's patience, and the moment attendees start dismissing pushes unread (or disabling them entirely), the channel is dead for everyone: sponsors, and your own operational messages that safety and schedule changes depend on. In practice, organizers cap sponsored pushes hard (a handful per day across all sponsors), keep approval over copy and timing, schedule them around agenda moments rather than clustering them at once, and require each push to contain something actionable — a place, a time, a reason to move. The common mistake is selling pushes to every gold sponsor as a package line item, then discovering you've promised twenty-five notifications across two days. Sell scarcity; it's the whole product. One honest nuance: delivery isn't guaranteed — plenty of attendees decline notification permissions at install, so the real reached audience is a fraction of app downloads. Quote reach on opted-in numbers, not total installs.
