Common questions about notification system architecture generator
Event bus receives triggers → notification service determines channels (email, SMS, push, in-app) based on user preferences → routes to channel-specific services (SendGrid, Twilio, FCM/APNS). Show preference management, delivery tracking, and retry logic for failed deliveries.
App registers device token with FCM (Android) or APNS (iOS) → backend stores tokens by user → notification service sends to FCM/APNS → cloud service delivers to devices. Diagram shows token lifecycle, topic subscriptions, and handling of expired tokens.
Use email service providers (SendGrid, AWS SES, Postmark). Show template management, personalization engine, sending queues, bounce/complaint handling, unsubscribe management. Include DKIM/SPF/DMARC for deliverability and separate transactional vs marketing email flows.
Store preferences per notification type and channel in user profile. Visualize notification event → preference lookup → channel selection → delivery. Include opt-in/opt-out management, quiet hours, notification grouping, and digest options for batching similar notifications.
Use message queues for durability, retry with exponential backoff, track delivery status, implement dead letter queues for permanent failures. Show idempotency handling to prevent duplicates, circuit breakers for third-party service failures, and fallback channels when primary channel unavailable.
