Notifications are the nervous system of your SaaS product -- they drive engagement, communicate critical events, and keep users informed. But poorly implemented notifications lead to alert fatigue and user churn. We build event-driven notification systems with multi-channel delivery, granular user preferences, intelligent batching, and delivery tracking that keep users engaged without overwhelming them.

Multi-channel notification infrastructure that keeps users engaged without overwhelming them
Send notifications via email (SendGrid, SES, Postmark), push notifications (FCM, APNs), SMS (Twilio, SNS), in-app notification center, Slack, Microsoft Teams, and webhooks. Channel selection is automatic based on notification urgency, user preferences, and delivery context -- critical alerts go to all channels while routine updates stay in-app.
Notifications are triggered by application events published to a message queue (RabbitMQ, Redis Streams, or SQS). The notification service subscribes to events, resolves recipients, applies preference filters, renders templates, and dispatches to the appropriate channels. Fully decoupled from your application code -- add new notification types without modifying business logic.
Granular notification preferences where users control which notifications they receive and on which channels. Category-based preferences (billing, product updates, team activity), per-channel toggles, quiet hours configuration, and digest frequency settings. Preferences are enforced at the infrastructure level so developers cannot accidentally bypass them.
MJML-based email templates and markdown-based notification content with dynamic variables, conditional blocks, and localization support. Admin-editable templates via a visual editor so marketing and product teams can update notification copy without developer involvement. Version history and A/B testing support for template optimization.
End-to-end delivery tracking for every notification -- sent, delivered, opened, clicked, bounced, or failed. Aggregated analytics showing delivery rates per channel, engagement rates per notification type, and unsubscribe trends. Alerting for delivery rate drops that might indicate provider issues or template problems.
Intelligent notification batching that groups related events into digest summaries instead of sending individual notifications. Configurable digest windows (hourly, daily, weekly) with smart grouping by category. Priority bypass for critical notifications that should never be batched. Reduces notification volume by up to 70% while improving information density.

A proven 5-step process to build notification infrastructure that drives engagement
We catalog every event in your application that should trigger a notification, classify them by urgency and category, define the recipient resolution logic, and map each notification to the appropriate delivery channels. We design the preference model and batching rules before implementation begins.
Design and build the event-driven pipeline -- message queue setup, event publishers in your application code, the notification service that consumes events, and the channel delivery adapters. We implement dead letter queues for failed deliveries and idempotency to prevent duplicate notifications.
Build MJML email templates, in-app notification components, push notification payloads, and SMS content for every notification type. Implement the template rendering engine with dynamic variables, conditional sections, and localization. Connect delivery providers (SendGrid, Twilio, FCM) with fallback routing.
Build the user preference management UI and API, implement preference enforcement in the delivery pipeline, and create the smart batching engine that aggregates notifications into digests. Test every preference combination to ensure users receive exactly what they opted into.
Production deployment with delivery tracking dashboards, channel health monitoring, bounce rate alerting, and engagement analytics. 30-day post-launch support with iterative tuning of batching rules, delivery timing, and template content based on actual engagement metrics.
Flexible engagement models for SaaS notification infrastructure
"Edesy replaced our spaghetti of notification code with a clean event-driven system. Adding a new notification type used to take 2 days of developer time across frontend and backend. Now it takes 30 minutes to define the event, template, and channel routing. Our notification delivery rate improved from 87% to 99.5%."

"The smart digest feature was a game changer. Our users were getting 30-40 emails a day from our platform and complained constantly. The daily digest reduced that to a single well-organized summary. Email unsubscribe rates dropped from 8% to 0.5% and click-through rates actually tripled."

"We handle 800,000+ notifications per day across email, push, and in-app channels with the system Edesy built. The event-driven architecture handles load spikes gracefully and the delivery tracking gives us complete visibility. When SendGrid had an outage last month, the automatic failover to SES kicked in and our users did not notice."
