How to Optimize Your Push Notification System to Prevent Spam Classification

Building an effective push notification system for your web application can significantly enhance user engagement. However, ensuring that your notifications are delivered correctly and not marked as spam can be challenging. If you’ve recently implemented push notifications in your Next.js-based project and find they’re being treated as spam, you’re not alone. Here’s a professional guide to help you troubleshoot and optimize your notifications for maximum effectiveness.

Understanding Common Challenges with Web Push Notifications

When deploying web push notifications, several factors influence whether they reach the user’s device favorably or are flagged as spam. Even with meticulously configured options like icon, badge, TTL (Time To Live), tags, and collapse keys, some notifications still get overlooked or suppressed.
