Troubleshooting Push Notifications: From Successful Implementation to Spam Filtering
Implementing an effective push notification system can significantly enhance user engagement in your web application. Recently, I developed a push notification setup using Next.js and Ably, aiming to deliver timely updates to users. While the setup works smoothly on the technical front, I encountered an unexpected challenge: notifications are being marked as spam or ignored by users.
The Journey to Build a Robust Notification System
Using Next.js, I opted for Ably’s push notification service due to its reliability and ease of integration, especially since native WebSockets aren’t feasible in this environment. After successfully deploying and testing the system, most notifications appear as intended — they wake the device, appear in the notification center, and display the designated app icon.
The Challenges Faced
Despite following best practices and configuring parameters such as icon, badge, TTL, tag, collapse key, and ensuring silent and renotify options are appropriate, the notifications are still being classified as spam by browsers or devices. This leads to poor visibility and low user interaction.
Goals for Optimal Notifications
To improve the effectiveness of push alerts, I want notifications to:
- Wake up users’ devices promptly
- Be prominently displayed in the notification center
- Show my app’s logo instead of default browser icons
- Properly group notifications with the same tag or collapse key, avoiding duplicates
Additionally, I am exploring whether web push notifications can include actionable elements, such as “Like” or “Reply” buttons, to foster more engaging interactions.
Key Takeaways and Next Steps
-
Review Notification Content and Delivery Timing: Ensure your message content is relevant and not overly aggressive, which spam filters tend to flag.
-
Properly Configure Notification Metadata: Confirm that icon, badge, and other visual elements adhere to best practices, and that TTL and other timing parameters are appropriate.
-
Check User Permissions: Make sure users have granted appropriate notification permissions and that opt-in procedures are transparent.
-
Evaluate Browser and Service Settings: Different browsers and platforms have varying spam filters and policies; tailoring your approach accordingly can improve delivery.
-
Consider Adding Action Buttons: Web push supports action buttons, which can increase engagement. Verify browser compatibility and implement accordingly.
By refining these aspects, you can enhance your push notification delivery, ensuring your messages reach users effectively without being mistaken for spam.
