How does push notification (via Klaviyo/WebEngage) helps in app growth?

Last updated: May 28, 2026

From a growth perspective, push notifications provide a wealth of data points that help brands optimize for retention, conversion, and acquisition ROI. These data points can be categorized into Event-Level Data (behavioral), Segmentation Attributes (user profile), and Growth KPIs (performance).

1. Behavioral Event Data (The "Triggers")

These data points are sent from the Appbrew SDK to your CRM (Klaviyo/WebEnagge) in real-time. They tell you what a user is doing so you can nudge them back.

  • Viewed Product: Captures Product ID, Price, and Image URL. Use this for "Browse Abandonment" pushes.

  • Added to Cart: High-intent signal including Cart Value and Item Details. Use this for "Cart Recovery" flows.

  • Started Checkout: Final stage signal. Use this for "Checkout Abandonment" flows.

  • Opened App: Tracks frequency of usage. Use this to identify "Loyal Users" vs. "Churn Risks."

  • App Installed: A one-time growth signal to trigger "Welcome Series" notifications.

2. User Segmentation Attributes (The "Who")

These properties are stored on the user's profile and help you create targeted audiences for growth campaigns.

  • Device Type (iOS vs. Android): Crucial for testing specific platform campaigns.

  • App Version & Build: Helps identify if a user is on an old version and needs a "Mandatory Update" nudge.

  • Push Consent Status: Tracks who has opted-in, allowing you to focus multi-channel efforts (SMS/Email) on the opt-out users.

  • Location/Geofencing: New data point used to trigger pushes when a user enters a specific physical area.

  • Last Purchase Date: Used to calculate "Days Since Last Purchase" for win-back campaigns.

3. Growth KPIs & Attribution (The "Impact")

These metrics measure the direct ROI of your push notification strategy.

  • Received Push: Confirms deliverability (helps audit your APNs/FCM setup).

  • Opened Push (CTR): The primary engagement metric. A high CTR indicates strong copy and relevance.

  • Revenue Attribution: The most critical growth metric. Our analytics attribute revenue to a push notification for up to 7 days after the click.

  • App AOV vs. Web AOV: Many brands see significantly higher Average Order Value (e.g., $250 vs $200) from users who engage via app push.

  • Retention Rate: Comparing the lifetime value (LTV) of users who have push enabled vs. those who don't.

4. ROI & Performance Disconnects

Data points also help identify growth blockers. For instance, Bailey's CBD used push data to find that while their App CVR (1%) and AOV ($66) were high, their overall acquisition was low because only ~13% of their Klaviyo base was push-enabled

Summary for Growth Teams: Use Event Data to automate conversion, Segmentation Attributes to personalize the journey, and Attribution Metrics to prove that the app is a high-margin revenue channel compared to paid ads or email.
