Don’t overdo push notifications
Notifications that come too frequently are like annoying waiters who keep approaching your table every 10 minutes to ask if everything is okay or if you need anything else. Such behavior makes your app look unprofessional and needy and forces users to turn off notifications, or, worse, delete the app.
First, explore your users’ needs and learn what information they find relevant and how often they consent to see it.
Second, avoid sending multiple notifications in bursts. Consider if you can combine a few notifications into a single message. Also, figure out if your users actually find all your notifications useful. Focus on quality rather than quantity.
