Every channel. One module.
Email, SMS, push, and in-app notifications — templated, tracked, and preference-managed in a single system instead of four piecemeal ones.
Every channel. One module.
Your application needs to send emails, SMS, push notifications, and in-app alerts — each with different templates, delivery requirements, and user preferences. Building this piecemeal leads to inconsistent experiences and maintenance nightmares. This module unifies all channels into a single, manageable system.
Features
Send, track, and let users stay in control.
Multi-channel delivery
Email — transactional and marketing via SendGrid, SES, or SMTP; SMS — text notifications via Twilio or compatible providers; push — browser and mobile notifications via Firebase; and in-app — a real-time notification feed with WebSocket support.
Template engine
HTML and plain-text templates with Django template language; dynamic variables that merge user data, object data, and custom fields; template versioning to manage and preview templates before deploy; and localization with multi-language templates for international audiences.
Delivery management
Delivery tracking from sent to delivered, opened, clicked, and failed; automatic retry for failed deliveries with exponential backoff; rate limiting to prevent notification flooding per user and per channel; and scheduling to send at a specific time or in the user’s timezone.
User preferences
Per-channel opt-in/opt-out so users control which notifications they receive on which channel; digest mode that batches notifications into daily or weekly summaries; quiet hours that respect user-configured do-not-disturb windows; and a pre-built React preference UI for notification settings.
Technical Details
| Component | Implementation |
|---|---|
| Backend | Django, Celery for async delivery, Redis for real-time |
| API | DRF viewsets for notification history and preferences |
| Frontend | React notification bell, feed component, preferences editor |
| Real-time | Django Channels / WebSocket for in-app notifications |
| Providers | SendGrid, AWS SES, Twilio, Firebase (pluggable) |
Integration Time
Typically 3–7 days for a core notification system (email + in-app). SMS and push timelines depend on provider setup and compliance requirements.
Pairs Well With
User Management — invitation and lifecycle notifications.
Auth, SSO & RBAC — login alerts and security notifications.
Audit Log — alert on suspicious activity.
Frequently asked questions
How long does integration take?
Typically 3–7 days for a core notification system covering email and in-app. SMS and push timelines depend on provider setup and compliance requirements.
Which channels and providers are supported?
Email via SendGrid, AWS SES, or SMTP; SMS via Twilio or compatible providers; browser and mobile push via Firebase; and a real-time in-app feed with WebSocket support. Providers are pluggable.
Can users control what they receive?
Yes — per-channel opt-in/opt-out, digest mode that batches notifications into daily or weekly summaries, and quiet hours that respect user-configured do-not-disturb windows, all managed in a pre-built preferences UI.
What happens when delivery fails?
Automatic retry with exponential backoff, rate limiting to prevent flooding per user and per channel, and delivery tracking from sent through delivered, opened, clicked, and failed.
