Instant AI’s Back in Stock Flow triggers 1 hour after a product is added back into stock. The short delay helps avoid false triggers if stock levels fluctuate.
Who gets enrolled
-
Shoppers who viewed the product in the last 60 days.
-
We’ll automatically exclude shoppers who already purchased the product in that time (e.g. if someone bought it 45 days ago, then it went out of stock, they won’t be re-enrolled).
-
If a shopper adds the product to cart, they’ll also be excluded. That’s because once it’s in their cart, we prioritise abandoned cart emails over back in stock.
How the flow works
-
By default, Back in Stock runs as a 3-part email series, but you can customise this to add or remove touchpoints.
-
Emails only send if the shopper is not already in an active abandonment flow (e.g. Abandoned Checkout). Abandonment takes priority.
-
Coupons aren’t included by default, but you can enable them in coupon settings.
Shopify inventory requirements
-
Only works with standard Shopify inventory management. Third-party inventory apps are not supported.
-
If you have multiple locations, the product will count as “in stock” if at least one location can fulfil online orders.
-
If a product has “Continue selling when out of stock” turned on, we’ll never send a back in stock flow for it.
-
The product must be published and available on the Online Store for the flow to trigger. If stock is added to a draft or unpublished product, no emails will send.

FAQ's
How can I delay sending a back in stock email?
If you want to pause emails, make sure the product is not available to order online. In Shopify, you can keep the product published (so it still shows on your site) but remove its Online Store availability or mark it as unavailable for purchase. While it’s visible but not purchasable, Instant won’t trigger a back in stock email. As soon as it’s both published and purchasable with stock available, the flow will send.
What happens if a customer returns stock?
Any increase in stock counts — whether it’s from a return, manual adjustment, or receiving new stock. If the product is published and purchasable, this will trigger a back in stock flow to all shoppers who viewed it in the past 60 days (and haven’t purchased or added it to cart since). If the product is unpublished or unavailable online, no email will send.
