Notifications That Engage Without Annoying
Multi-channel delivery, user preferences, and intelligent batching — a notification system that keeps users informed, not overwhelmed.
Use Case: Notification System
Problem
Applications hardcode notifications, send too many, and lack preference controls. Users disable notifications entirely, missing critical updates. Engineering teams rebuild notification logic for every new channel.
Solution
A custom notification system provides a centralized service for all application notifications with multi-channel delivery (email, push, SMS, in-app), user preference management, intelligent batching, and template management.
Key Features
- Multi-Channel Delivery: Unified API sending notifications via email, push, SMS, in-app, Slack, and webhook with channel fallbacks.
- Preference Management: User-facing preference center for channel and category opt-in/out with system-level overrides for critical alerts.
- Intelligent Batching: Digest notifications that batch frequent updates into periodic summaries to reduce notification fatigue.
Estimated Scope
Hours: 200–350 | Cost: $400–$1,750 | Timeline: 4–7 weeks
Frequently Asked Questions
- What channels does it support?
- Email (SendGrid, SES), push (FCM, APNs), SMS (Twilio), in-app, Slack, Microsoft Teams, and custom webhooks — with easy addition of new channels.
- Can users control which notifications they receive?
- Yes. A preference center lets users opt in/out by category and channel, with mandatory overrides for security and billing notifications.
- How does notification batching work?
- The system collects frequent events into digest notifications delivered on configurable schedules (hourly, daily) instead of sending each event immediately.
