Need push notifications with user segmentation and targeting

I can help design that. To set up push notifications with user segmentation and targeting, you generally need four pieces:

1) Collect user attributes and events

Store data like:

• Location: country, city, timezone
• Behavior: app opens, purchases, last active date
• Profile: plan type, language, age group
• Device: iOS/Android, app version

2) Define segments

Examples:

• New users who signed up in the last 7 days
• Users who haven’t opened the app in 14 days
• Paid users in the US
• Users who added to cart but didn’t purchase
• Users on Android running an old app version

3) Target notifications

Send push campaigns to segments using rules like:

• If last_active < 7 days and plan = free
• If purchase_count = 0 and signup_date > 3 days ago
• If country = US and language = en

4) Use a push platform or backend

Common options:

• Firebase Cloud Messaging (FCM) for Android/web
• Apple Push Notification service (APNs) for iOS
• A push provider like OneSignal, Braze, Airship, or Customer.io
• Or your own backend + segmentation engine

Typical architecture

• App sends user/device data to backend
• Backend stores user profile + events
• Segmentation job builds audience lists
• Notification service sends push via FCM/APNs
• Track delivery, opens, conversions

Best practices

• Keep segments dynamic and updated
• Avoid over-notifying users
• Personalize content when possible
• Respect consent and privacy rules
• Measure performance: open rate, CTR, conversion

If you want, I can also provide:

1. a database schema for segmentation,
2. a backend API design, or
3. example implementation using FCM + Python/Node.js.
