# RateRight Push Notifications Specification

## Executive Summary
Push notifications are critical for RateRight's marketplace success. They connect workers with job opportunities in real-time and keep contractors informed about applicant activity. This specification outlines a comprehensive strategy for implementing effective, non-intrusive push notifications that drive action without overwhelming users.

## 1. Notification Types

### For Workers
- **New Job Match**: Alert when jobs are posted matching their skills/location
- **Application Status**: Confirmation when application is received
- **Hiring Confirmation**: When hired for a job
- **Job Reminder**: 24 hours before job starts
- **Payment Received**: When payment is processed
- **Rating Reminder**: Prompt to rate contractor after job completion

### For Contractors
- **New Application**: When a worker applies to their job
- **Applicant Available**: When a matched worker is available
- **Job Filled**: Confirmation when position is filled
- **Worker Cancelled**: When hired worker cancels
- **Payment Reminder**: When payment is due
- **New Message**: Direct messages from workers

### System Notifications
- **Profile Incomplete**: Reminder to complete profile
- **Verification Required**: Account verification needed
- **Maintenance**: Scheduled downtime alerts

## 2. Content Strategy

### Principles
- **Be Specific**: Include job type, location, and pay rate
- **Create Urgency**: For time-sensitive opportunities
- **Personalize**: Use names and reference past activity
- **Be Actionable**: Clear next steps ("Tap to apply", "View applicants")

### Examples

**Worker - New Job Match**:
> "🏠 Plumbing job in North Sydney - $150/hr - 3 applicants needed. Tap to apply in 30 seconds."

**Contractor - New Application**:
> "👷 Mike (4.8★) applied for your electrical job. View his profile and 12 years experience."

**Worker - Hiring Confirmation**:
> "🎉 You're hired! Painting job tomorrow at 123 Main St, 9 AM. $200 total. Get directions?"

## 3. Timing Rules

### Smart Delivery Windows
- **Business Hours**: 8 AM - 8 PM local time
- **No Early/Late**: Never send before 7 AM or after 9 PM
- **Weekend Considerations**: Reduce frequency on weekends unless urgent

### Frequency Caps
- **Workers**: Max 5 job alerts per day, 15 per week
- **Contractors**: Max 10 applicant alerts per day
- **System**: Max 1 non-urgent notification per week

### Batching Strategy
- **Job Matches**: Batch every 2 hours during peak times
- **Applications**: Real-time for first 24 hours, then batched
- **Marketing**: Weekly digest only, with clear opt-out

## 4. Technical Approach

### Platform Architecture
```
RateRight Backend → Notification Service → Provider → Device
                    ↓
            User Preference Store
```

### Provider Selection
**Primary: Firebase Cloud Messaging (FCM)**
- Free tier: 1M notifications/month
- Cross-platform support (iOS/Android/Web)
- Real-time delivery
- Built-in analytics

**Secondary: OneSignal**
- Backup provider for redundancy
- Advanced segmentation features
- Better support for A/B testing

### Implementation Stack
- **Backend**: Node.js with Firebase Admin SDK
- **Mobile**: React Native with Firebase Messaging
- **Web**: Service Worker with Web Push API
- **Queue**: Redis for reliable delivery

### iOS vs Android Considerations
- **iOS**: Must go through APNs (Apple Push Notification Service)
- **Android**: Direct FCM integration
- **Permission Handling**: iOS requires explicit permission, Android auto-opt in
- **Rich Notifications**: Both support images, action buttons

### Web Push for PWA
- **Service Worker**: Background notification handling
- **VAPID Keys**: For secure authentication
- **Browser Support**: 96% coverage, iOS Safari requires installed PWA

## 5. User Preferences

### Opt-in Flow
1. **Soft Ask**: Explain benefits before system prompt
2. **Value Proposition**: "Get notified about jobs matching your skills"
3. **System Prompt**: Only after user shows interest

### Preference Center
- **Notification Types**: Toggle each category
- **Delivery Method**: Push, SMS, Email, In-app only
- **Quiet Hours**: Custom do-not-disturb windows
- **Frequency**: Daily digest vs real-time
- **Location Radius**: How far to search for jobs

### Smart Defaults
- **Workers**: Job matches on, marketing off
- **Contractors**: Applications on, marketing off
- **Time Zone**: Auto-detect and respect local time

## 6. Implementation Plan

- [ ] Add basic preference management

### Phase 2: Enhancement (Week 3-4)
- [ ] Add remaining notification types
- [ ] Implement smart timing rules
- [ ] Create preference center UI
- [ ] Add notification analytics
- [ ] Implement batching logic

### Phase 3: Optimization (Week 5-6)
- [ ] A/B testing framework
- [ ] Advanced personalization
- [ ] Web push for PWA
- [ ] OneSignal integration for redundancy
- [ ] Performance monitoring

### Phase 4: Advanced Features (Week 7-8)
- [ ] Machine learning for optimal timing
- [ ] Predictive notifications
- [ ] Rich media support
- [ ] Geofenced notifications
- [ ] Multi-language support

## 7. Success Metrics

### Engagement Metrics
- **Opt-in Rate**: Target 60% (Android), 45% (iOS)
- **Open Rate**: Target 8-12% overall
- **Click-through Rate**: Target 15% for job notifications
- **Conversion Rate**: Target 25% of clicks lead to application

### Quality Metrics
- **Unsubscribe Rate**: Keep below 2% monthly
- **App Uninstalls**: Track correlation with notifications
