## 🎯 Notification Best Practices

### User Experience Guidelines

#### Notification Frequency Management
```
🎯 Smart Frequency Controls:

Daily Limits:
• Comments: Max 10 notifications
• Likes/Reactions: Max 5 notifications
• Security Alerts: No limit (critical)
• Performance Updates: Max 3 notifications

Batching Rules:
• Similar notifications grouped together
• Non-urgent items bundled into digests
• Time-sensitive alerts sent immediately
• User-configurable batching preferences

Escalation Logic:
1. First notification: Immediate
2. Similar notifications: 1-hour delay
3. Multiple similar: Batch into digest
4. User interaction: Reset frequency counter
```

#### Content Relevance Scoring
- **Engagement History** - Based on past interactions
- **Content Preferences** - User's stated interests
- **Timing Patterns** - When user typically engages
- **Device Context** - Notification appropriateness for device
- **Social Signals** - Community engagement levels
