There are many forms of engagement through push notifications. Try one or more from the following based on your app and its customers:
1. Getting users back. Customer retention is an important metric when tracking traction for your app. The way to bring back users who have downloaded your app and haven’t come back to it beyond the first or first few times is to send them subtle reminder messages that tempt them back or make them want to be a part of the conversation.
2. Offers and deals. Who isn’t looking for a good deal? Push notifications will help to not only send out what’s new, but through targeted and optimized analytics, you can send out notifications that are relevant to the customer and at the most appropriate times.
3. Helpful content. I have a couple of accounts from different banks. I have apps from both the banks. One sends me a push notification every week with my balance and every time there’s any activity in my account. The other doesn’t. Which one am I more likely to be engaged with? No points for guessing this one.
Push notifications are attention grabbing in nature and lend themselves to immediacy. Keep this in mind and deliver personalized, timely and relevant alerts to bring users back to your app.
