> Let shoppers ask to be emailed when a product or size is available again, online or in a specific store.

*(Starter and up)*

When a variant is out of stock, the assistant can offer "Email me when it's back", online or for a specific store.

1. The shopper enters an email; new addresses get a confirmation email first.
2. When stock arrives (the next sync or push), ShopAssist checks the stock live and sends one email per day with all the shopper's products that are back (up to 10), including the price at the time of sending.
3. Subscriptions end when the email is sent, or after the retention period.

Back-in-stock alerts are a service the shopper asked for, not marketing; they don't subscribe anyone to your newsletter. Every email has an unsubscribe link.

Switch it on in **Orders & actions → Back in stock**. Subscriptions are listed in **Engagement** and available by [API](/docs/api/reference/engagement/list-back-in-stock) and the `back_in_stock.*` [webhooks](/docs/webhooks/events).
