Day 46: Building Smart Notification Preferences
What We’re Building Today
Today we’re creating the brain behind user notification preferences - the system that lets users control when, how, and what notifications they receive. Think of it as building the notification settings page you see in Slack, Discord, or GitHub, but with intelligent features like quiet hours and escalation rules.
Key Components:
User preference storage models
Channel prioritization (email > SMS > push)
Quiet hours with timezone awareness
Smart escalation rules for urgent notifications
Subscription management dashboard
The Problem: Notification Fatigue vs Missing Critical Updates
Every modern application faces this challenge: send too many notifications and users disable them entirely. Send too few and users miss critical updates. The solution? Let users precisely control their notification experience.
Real-World Context: Slack processes over 10 billion notifications daily, but their users only see what matters to them because of sophisticated preference management. PagerDuty’s escalation rules ensure critical alerts reach the right person even if they’re sleeping.
