Build a notification system — the right message at the right time.
Notifications drive engagement. In-app, email, SMS, and push notifications — each channel has a different role. A custom notification system handles all channels from a single event, with user preferences controlling what they receive.
Platform founder who needs multi-channel notifications (in-app, email, SMS, push) driven by platform events, with user preference controls
Notifications are the engagement engine of every platform. But notifications without a proper system become an unmanageable mess:
- Every notification is hardcoded in the feature code
- No central place to see what notifications exist
- User preferences don't exist — everyone gets everything
- Notification content is in the code, not editable by non-developers
- No delivery logging — can't tell if a notification was sent or received
What a notification system provides: A central registry of notification types. An event-driven dispatch system. Multi-channel delivery. User preferences. Delivery logging.
Notification channels and their roles:
- In-app: Real-time, non-interruptive. Visible in the app notification bell.
- Email: Important events. Digests. Transactional confirmations.
- SMS: Urgent, time-sensitive alerts requiring immediate attention.
- Push (mobile): Re-engagement for mobile apps.

Questions, answered.
Resend for transactional email — modern API, React Email templates, excellent deliverability. Postmark as an alternative. SendGrid for high volume.
Rate limiting per user per notification type. Digest mode for high-frequency events (e.g., one daily digest instead of 20 individual emails). User-controlled digest settings.
