What Are Push Notifications?
Push notifications are short, clickable messages delivered directly to a user's device — a smartphone, tablet, or desktop — even when they're not actively using your app or website. They appear as banner alerts, lock screen messages, or notification center entries, making them one of the most direct channels available for reaching your audience in real time.
They're called "push" because the server pushes the message to the device, as opposed to the user actively pulling (requesting) information.
Types of Push Notifications
- Mobile app push notifications — Sent via iOS or Android apps. Require the user to grant permission first.
- Web push notifications — Delivered through browsers like Chrome or Firefox. Users opt in via a browser prompt on your website.
- Desktop push notifications — Similar to web push, but delivered to the native notification tray of a computer's operating system.
- In-app notifications — Appear inside the app while the user is actively using it. Different from standard push but often part of the same strategy.
How the Delivery Process Works
Understanding the technical flow helps you troubleshoot and optimize your strategy:
- User subscribes — The user grants notification permission on your app or website.
- Token generated — The device creates a unique push token, which identifies that specific device for future messages.
- Token stored — Your notification platform stores the token in its database.
- Message triggered — You compose a notification and send it through your platform (e.g., Firebase, OneSignal, Braze).
- Platform routes it — The message goes to Apple's APNs (for iOS) or Google's FCM (for Android/web).
- Device displays the notification — The message appears on the user's screen.
Key Components of an Effective Push Notification
| Element | Best Practices |
|---|---|
| Title | Keep it under 50 characters. Make it specific and intriguing. |
| Body text | One clear, actionable sentence. Avoid jargon. |
| Call to action | Use action verbs: "View", "Claim", "Read", "Join". |
| Timing | Send at times relevant to the user's behavior or timezone. |
| Frequency | Less is more. Overuse leads to opt-outs. |
Common Mistakes to Avoid
Sending Too Many Notifications
Notification fatigue is real. If users feel bombarded, they'll either silence your notifications or uninstall your app entirely. Start with fewer, more targeted messages and scale up gradually based on engagement data.
Generic, Untargeted Messages
Blasting the same message to every subscriber rarely performs well. Segment your audience by behavior, preferences, or location and tailor messages accordingly. A notification that feels personal gets clicked; one that feels like spam gets dismissed.
Poor Timing
Sending a push notification at 2 a.m. local time is a quick way to earn an unsubscribe. Use timezone-aware scheduling tools to deliver messages at appropriate hours for each recipient.
Push Notifications for Event Communication
Push notifications are particularly powerful for event management. Consider using them to:
- Send event reminders 24 hours and 1 hour before the start.
- Notify registered attendees of schedule changes or venue updates.
- Share live updates during the event (speaker announcements, session starts).
- Follow up post-event with thank-you messages or survey links.
When used thoughtfully, push notifications transform one-way event communication into an interactive, real-time experience.
