Push Notification Marketing for E-Commerce: When and How to Use Them

Push notification marketing for e-commerce offers a direct line to customers even when they're not on your website or in your app. With opt-in rates of 40-60% on desktop and 30-50% on mobile (PushEngage, 2025), push notifications rival email in reach while delivering engagement rates that far exceed it.

Here's how to build a push notification strategy that drives e-commerce revenue without annoying your subscribers.

Why Push Notifications Matter for E-Commerce

• Click-through rate of 4-8%, compared to email's 2-3% (PushEngage, 2025)
• Conversion rates of 2-5% for well-targeted push campaigns (Airship, 2025)
• Push notifications reach users even when they're not on your site, making them ideal for re-engagement

Push notifications work best when used as part of a multi-channel strategy alongside email, SMS, and WhatsApp. Each channel serves a different purpose.

Best Push Notification Campaign Types

1. Price Drop Alerts

Notify customers when a product they've viewed drops in price. These convert at 12-18% — among the highest of any push campaign type.

2. Back-in-Stock Alerts

When a popular item comes back in stock, a push notification can drive immediate sales. Back-in-stock alerts see conversion rates of 15-25% within 24 hours (Yotpo, 2025).

3. Abandoned Cart Reminders

A push notification 48 hours after abandonment can recover additional sales beyond email and SMS. Keep it brief: "Your cart is waiting. Complete your order."

4. Re-engagement Campaigns

For customers who haven't visited in 30+ days, a push notification with a personalized offer can bring them back. Re-engagement pushes have an average conversion rate of 3-5%.

5. Flash Sales

Time-limited sales announced via push notification drive immediate traffic. Use urgency in your messaging — "24-hour sale ends tonight" — to maximize conversions.

Push Notification Best Practices

• Keep it short: Push notifications should be 50-100 characters maximum. Mobile notifications are truncated after ~120 characters
• Personalize the message: Include the customer's name, the specific product, or their abandoned cart items
• Use rich media: Images in push notifications increase engagement by 2-3x (Airship, 2025)
• Respect frequency caps: Limit to 1-2 promotional pushes per week per subscriber
• Time delivery carefully: Send during business hours in the customer's timezone. Avoid early morning or late night
• A/B test your copy: Test different CTAs, urgency levels, and personalization strategies

Measuring Push Notification Performance

Key metrics to track for push campaigns:

• Delivery rate: % of pushes successfully delivered (aim for 95%+)
• Click-through rate (CTR): % of delivered pushes that were clicked (benchmark: 4-8%)
• Conversion rate: % of clicks that resulted in a purchase (benchmark: 2-5%)
• Opt-out rate: % of subscribers who disable notifications after a campaign (alert if >2%)

Push vs Other Channels

Push notifications complement email and SMS rather than replacing them. Use this framework to decide which channel to use:

• Email: Detailed information, newsletters, product recommendations
• SMS: Urgent or time-sensitive messages with immediate action expected
• Push: Quick reminders, alerts, and re-engagement nudges

With EngageApp, you can orchestrate push notifications alongside email, SMS, and WhatsApp in a single multi-channel campaign builder.

FAQ

How do I increase push notification opt-in rates?

Show the opt-in prompt after a user has had a positive experience on your site (e.g., after adding an item to cart or completing a purchase). Pre-prompt with a soft ask explaining the value — "Get notified when your cart is about to expire" — before the browser-level prompt. This can increase opt-in rates by 25-35%.

Can I send push notifications without a mobile app?

Yes. Web push notifications work on desktop and mobile browsers without requiring a native app install. They're supported on Chrome, Firefox, Safari, Edge, and other modern browsers.

How do I handle push notification unsubscribes?

When a user unsubscribes from push notifications, the browser or device handles removal automatically. To re-engage previously unsubscribed users, you'll need to ask them to re-subscribe through a new opt-in prompt — but only send this once to avoid being seen as annoying.
