Notification Design in Your Application
Notifications — in-app alerts, push notifications, email digests — are how your application communicates with users about events they care about. Designed well, they provide value and drive engagement. Designed poorly, they create notification fatigue and are muted or ignored.
Types of Notifications
- Toast/snackbar: Temporary, unobtrusive messages that appear briefly and disappear. Used for non-critical confirmations ("Changes saved") or alerts that require no action.
- Inline notifications: Banners or callouts embedded in the page content. Used for persistent contextual information or warnings relevant to the current task.
- Alert dialogs: Interrupting messages that require user action before proceeding. Reserved for critical situations only.
- Notification centres: A dedicated area (bell icon in nav) where users can see all recent notifications. Allows non-urgent notifications without interruption.
- Push notifications: Delivered outside the application via browser or mobile OS. Require explicit permission — respect the permission carefully.
Design Principles
- Only send notifications for events users genuinely care about
- Make notifications actionable where possible
- Allow users to customise which notifications they receive
- Use semantic colours: info (blue), success (green), warning (amber), error (red)
- Include timestamp information so users can assess urgency
