The Back-in-Stock Alert campaign sends an automated push notification to subscribers who opted in to restock alerts for a specific out-of-stock product on your Shopify store. When you update a product’s inventory to make it available again, PushEngage detects the change and notifies everyone waiting for that product.

This guide explains how the alert widget works, how to enable and customize it, and how to configure the notification campaign.

### Before You Start

- PushEngage is installed on your Shopify store.
- Back-in-Stock Alert campaigns require a PushEngage [Growth/Automation plan or above](https://www.pushengage.com/web-push-notifications-shopify-pricing/).
- The campaign is pre-built by PushEngage during onboarding. This guide covers enabling and customizing it.

### How Back-in-Stock Alerts Work

The Back-in-Stock Alert runs in two parts: a widget on your product pages that customers use to subscribe, and a trigger campaign that fires when inventory is restored.

1. A visitor lands on an out-of-stock product page and sees the Restock Alert widget.
2. They click **Notify me when back in stock** and subscribe.
3. When you update the product’s inventory in your Shopify admin to mark it as available, PushEngage detects the change.
4. Every subscriber who opted in for that product receives a push notification.

Subscribers only receive notifications for the specific products they opted in to. They will not receive alerts for other products unless they subscribe to those separately.

### Step 1: Enable the Alert Widget

The widget must be enabled for customers to subscribe to restock alerts on your product pages.

1. Log in to your [PushEngage dashboard](https://app.pushengage.com/).
2. Go to **Design » Widgets**.
3. Scroll down to **Alert Campaign Widget**.
4. Toggle the switch to **On**.

#### Customizing the Widget

Once enabled, customize the widget to match your store’s branding and encourage more opt-ins.

### Step 2: Open the Back-in-Stock Campaign

### Step 4: Set Notification Duration

**Recommended setting:** 48 hours

Enable **Keep notification open until user interaction** so the notification stays visible in the subscriber’s notification center until they act on it.

### Frequently Asked Questions

**Does the widget appear automatically on out-of-stock products?** The widget is enabled globally from the PushEngage dashboard. Once enabled, it appears on product pages based on how your Shopify theme renders it. Make sure the widget is positioned on pages where products are listed as out of stock so customers can see it.

**Can a subscriber opt in to restock alerts on multiple products?** Yes. A subscriber can opt in to restock alerts for as many products as they want. Each product maintains its own subscriber list.

**What if a product goes out of stock again after the alert fires?** If the product sells out again, subscribers are not automatically re-enrolled. They would need to visit the product page and subscribe again through the widget.

**Will subscribers who were notified automatically unsubscribe from that product’s alert?** After a restock notification fires, the subscriber has been notified. They remain subscribed to future restock events for the same product unless they unsubscribe.

**Can I add a second notification to follow up if the subscriber does not click?** Yes. Click **Add Notification** in the campaign editor to add a follow-up notification with a delay. Set the expiry of the first notification to match the delay of the second.
