How to Ensure Your Push Notifications Reach Users Effectively on Your Next.js App

Building a reliable push notification system is crucial for engaging your audience, but what happens when your carefully crafted alerts end up caught in spam filters or dismissed outright? If you’ve recently set up push notifications for your Next.js-based social media platform and encountered issues with notifications being marked as spam, you’re not alone. Here’s a comprehensive guide to understanding the common pitfalls and how to optimize your notifications for better delivery and engagement.

Understanding the Challenge

Many developers face challenges when implementing push notifications, especially when using third-party services like Ably. Even after seemingly correct configuration—setting icons, badges, TTL, tags, collapse keys, and other parameters—notifications can still be flagged as spam or ignored by users. This diminishes the effectiveness of your outreach and can negatively impact user experience.

Key Requirements for Effective Push Notifications

To improve the likelihood of your notifications being seen and interacted with, consider these essential goals:

1. Ensure Notifications Wake Devices: Your alerts should prompt the recipient’s phone to wake from sleep mode and display the message promptly.
2. Visibility in Notification Center: Notifications should appear clearly in the device’s notification bar, ensuring users are aware of new activity.
3. Branding and Visual Identity: Use your application’s logo or icon instead of default or generic images to reinforce your brand.
4. Smart Notification Management: Multiple notifications with the same context (e.g., same conversation or update) should be grouped or combined rather than cluttering the notification area with duplicates.

Best Practices for Effective Push Notifications

• Use Correct and Consistent Tags and Collapse Keys: Properly defining and updating these helps group notifications, preventing duplicates, and providing a seamless user experience.
• Set Appropriate Notification Options: Ensure parameters like icon, badge, ttl, renotify, and silent are correctly configured—while these do not guarantee delivery, they influence how notifications appear and behave.
• Optimize Content and Timing: Avoid overly promotional language and excessive frequency that could trigger spam filters.

Custom Actions in Web Push Notifications

Adding interactive elements such as “Like,” “Reply,” or “Mark Done” directly from the notification can significantly boost engagement. While browser support for actions varies, many modern browsers do support this feature through the actions field in the notification payload. Implementing this involves defining action buttons and handling their callbacks appropriately in your service worker.
