Push notifications are short messages sent directly to a user’s device or web browser, even when the application or website is not actively open.
They help businesses, applications, and websites deliver timely information such as updates, reminders, promotions, or alerts.
When used appropriately, push notifications can improve communication and increase user engagement. When overused, they can become intrusive and lead users to disable notifications altogether.

How push notifications work
Push notifications rely on a permission-based system.
Before receiving notifications, users must explicitly allow a website or application to send them.
Once permission is granted, the notification process typically works as follows:
- The user subscribes to notifications.
- The device registers with a notification service.
- The application or website sends a message to a notification server.
- The notification service delivers the message to the user’s device.
- The device displays the notification.
Notifications can appear on:
- smartphones
- tablets
- desktop computers
- smartwatches
- web browsers
Unlike emails or text messages, push notifications do not require users to open a specific application to receive updates.
Types of push notifications
Push notifications are commonly grouped into two categories.
Mobile push notifications
These notifications are sent by installed applications through operating system services such as:
- Apple Push Notification Service (APNs)
- Firebase Cloud Messaging (FCM)
Examples include:
- new messages
- account alerts
- order updates
- reminders
Web push notifications
Web push notifications are sent through supported web browsers.
Users can subscribe directly from a website without installing a mobile application.
Web push notifications are often used for:
- content updates
- marketing campaigns
- cart abandonment reminders
- service announcements
If you operate an online store, combining web push notifications with other communication channels can improve customer engagement. The article How to turn your company website into a lead-generating machine explains how different touchpoints can support conversions.
Common uses for push notifications
Push notifications are used across many industries.
Examples include:
- social media notifications
- breaking news alerts
- appointment reminders
- order status updates
- security alerts
- product availability notifications
- promotional offers
The most effective notifications provide information that is timely and relevant to the recipient.
Benefits of push notifications
When implemented carefully, push notifications can offer several advantages.
Immediate delivery
Notifications reach users quickly, making them useful for time-sensitive information.
Increased engagement
Timely reminders can encourage users to return to an application or website.
Personalization
Notifications can be tailored based on user preferences, location, or previous activity.
Improved customer experience
Relevant notifications help users stay informed without requiring them to search for information manually.
For example, customers may appreciate receiving notifications about shipping updates or account activity.
Challenges and considerations
Push notifications should be used responsibly.
Common challenges include:
- excessive messaging
- irrelevant content
- notification fatigue
- privacy concerns
Sending too many notifications can reduce engagement and increase opt-out rates.
Users should always have control over:
- notification preferences
- message frequency
- the types of notifications they receive
If your notifications contain personal information or behavioral data, make sure your practices comply with privacy regulations. See How to make your website GDPR compliant for more information.
Best practices for using push notifications
To improve effectiveness:
- ask for permission at an appropriate moment
- send notifications only when they provide value
- personalize content where possible
- limit notification frequency
- allow users to adjust preferences
- test different message formats and delivery times
Push notifications should support the user experience rather than interrupt it.
The article What should a good company website include to build trust? explains how clear communication contributes to long-term user engagement.
If your website relies heavily on mobile traffic, responsiveness also affects how users interact with notifications after opening them. See What does it mean for a website to be responsive? to learn more.
Summary
Push notifications allow websites and applications to send information directly to users in real time.
They can improve communication, increase engagement, and help users stay informed.
Their effectiveness depends on relevance, timing, and user control.
Well-designed notifications provide useful information while respecting user preferences and privacy.
