Messages delivered to a device even when the app is closed, through Apple's and Google's notification services. They can be broadcast to everyone or triggered by a specific event for one user.
Push is the only channel that reliably brings a user back into an app, and the fastest way to lose them: one irrelevant notification at the wrong hour is a common reason for uninstalling.
We ask for permission in context rather than on first launch, segment and schedule messages by behaviour and time zone, and give users granular settings — including a way to keep transactional alerts while muting marketing.
