How to send back in stock emails with shopify?

To send back-in-stock emails on Shopify, use a Shopify app like Back in Stock or Klaviyo's back-in-stock feature, which allows customers to subscribe to restock notifications and automatically sends emails when inventory is replenished. Swap's Inventory module's demand forecasting can help you anticipate which SKUs to prioritise for replenishment, ensuring timely restocks that maximise the value of your notification campaigns.
