What are web push notifications?

Web push notifications are messages sent directly to a user's browser on desktop or mobile. They appear on the screen even when the user is not on your website, allowing you to re-engage visitors instantly without needing email or phone numbers.

How is web push different from SMS?

Web push notifications don't require phone numbers and have no per-message cost. They are delivered through the browser and appear instantly on a user's device, whereas SMS relies on mobile networks and typically incurs per-message charges. Push is ideal for high-frequency, real-time engagement at scale.

How do customers subscribe to web push notifications?

Customers subscribe by clicking "Allow" on the browser permission prompt. This single opt-in requires no forms, emails, or phone numbers. Once subscribed, they can receive notifications from your store anytime.

What Shopify events can trigger automated push notifications?

Automated notifications can be triggered by key Shopify events such as product views, cart abandonment, purchases, price drops, and back-in-stock updates. These behaviour-based triggers ensure messages are timely and relevant to each customer.

Do web push notifications work on mobile?

Yes, web push notifications work on mobile devices through supported browsers. Subscribers can receive notifications on both Android and desktop. On iOS, support is available through modern browser implementations depending on the device and settings.

How does Mergn maximise push delivery?

Mergn uses a delivery-focused push engine that preserves subscriber tokens, retries failed deliveries, and monitors delivery health in real time. This ensures notifications reach as many subscribers as possible and helps maintain a strong, reliable delivery rate over time.

DELIVERY ENGINE

We make sure you don't lose a single subscriber.

Web push notifications are only effective when they reach the right audience. Mergn's delivery engine is designed to maximize reach by retaining subscriber tokens, retrying failed deliveries, and ensuring your notifications are delivered to the highest possible number of users.

Web Push Notification Token Retention

When users clear their browser data or switch devices, many platforms lose access to those subscribers. Mergn's system helps retain and recover web push notification tokens to preserve your audience and prevent subscriber loss.

Maximum Web Push Notification Delivery Rate

Each web push notification is optimized for maximum deliverability using intelligent routing, retry mechanisms, and browser behavior monitoring to ensure messages reach active subscribers effectively.

Real-Time Web Push Notification Analytics

Track real-time performance of web push notifications including delivery, clicks, and engagement, with detailed breakdowns by campaign and browser type for better optimization and insights.

CAMPAIGNS

Flash sales, new arrivals, back-in-stock. Sent in seconds.

Web push notification campaigns are delivered instantly to your entire subscriber base, appearing directly on users' screens without requiring email opens or SMS messages. This makes them ideal for time-sensitive marketing where delays can reduce conversions and revenue.

Flash Sale Announcements

When your flash sale begins, web push notifications are sent immediately so subscribers see the offer within seconds, ensuring real-time engagement instead of delayed email delivery.

Back-in-Stock Alerts

Web push notifications instantly alert subscribers when products are back in stock, helping you recover lost sales and capture demand before customers purchase elsewhere.

New Arrival Drops

Web push notifications help promote new product launches by instantly notifying your most engaged customers, driving early traffic, engagement, and conversions.

AUTOMATION

Behaviour-triggered push. Sends itself at the exact right moment.

The most effective web push notifications are triggered by real customer actions rather than mass broadcasts. By connecting directly with your Shopify store, Mergn automatically delivers the right message at the right moment based on user behaviour.

Abandoned Browse Alerts

When a customer views a product but does not add it to cart, an automated notification is sent within the hour, featuring the product details and a direct link back to the exact page they visited.

Cart Abandonment Recovery Notifications

If a cart is abandoned, customers receive a timely notification across devices even after leaving the site bringing them back with a single click to complete their purchase.

Price Drop Notifications

Customers who previously viewed a product are automatically notified when its price drops, helping convert interest into purchases without manual follow-up.

SHOPIFY INTEGRATION

“Push was the last channel we set up, and it turned out to be the most effortless one. The subscribers built up quietly over three months, and now every time we run a flash sale, the push alone drives more traffic in the first hour than anything else we send.”
