By default, Notify Me! sends a back-in-stock alert to all customers who requested notifications as soon as a sold-out product is restocked, even if only one item is added back to inventory.
Why set a minimum threshold?
If you have thousands of customers waiting on a popular product, restocking only a few units can lead to:
Frustrated customers who receive an alert but find the product sold out again by the time they visit your store.
Alerts being triggered by returns that restock a single item, unintentionally notifying everyone.
To prevent this, you can set a minimum inventory threshold so alerts are only sent when there is enough stock to meet demand.
How to set a store-wide minimum inventory threshold
Go to your Notify Me! dashboard.
Click Back in Stock in the left-side menu.
Go to Settings.
In the Back-in-stock notifications section, click Edit for First alert notification.
Click Set a minimum inventory threshold for notification alerts.
Enter your desired inventory threshold (must be greater than 0).
Note: Back-in-stock notifications will only send when the product’s available inventory exceeds this threshold.
How to set different minimum inventory thresholds for different products
You can configure product-specific thresholds using Shopify tags if you want different limits for high-demand and low-demand products.
How it works:
Tag products in Shopify using:
Restock-min-inventory-X
where X is the minimum stock required to send notifications.
Example:
If you want notifications to send only when at least 20 units are in stock, tag your product:Restock-min-inventory-20
Important details:
Tags apply at the product level for all variants.
Each variant must exceed the threshold for notifications for that variant to send. (Example: Each variant must have 20 units if the tag is Restock-min-inventory-20.)
Tags are case-sensitive. Use the exact format as shown.
Summary
Setting minimum inventory thresholds in Notify Me! ensures:
Customers receive back-in-stock alerts only when meaningful stock is available.
Prevents disappointment and reduces false demand signals.
Allows you to manage customer experience effectively, especially for high-demand products.
