What are back-in-stock notifications?

They're email signups for products that are out of stock. A customer who wants an item you can't sell them today leaves their email, and Simple Chat notifies them automatically when that variant is restocked. They can opt in from a notify-me control on the product page, or the assistant can register them if they ask in chat.

Signing up from the product page

The notify-me control collects the customer's email and registers the selected variant directly. Chat doesn't need to open for the signup to complete; a confirmation toast appears on the page once they're in. If they leave the email field empty, they're prompted to enter it right there rather than being sent into the assistant. This is the path for shoppers who only want a restock email, and the waitlist it feeds is tied to the variant they selected, not a generic product-level list.

Signing up mid-conversation

Chat remains an alternative path, not the only one. When a product is out of stock, the assistant can offer to email the customer once it's available again, right in the natural flow of a stock-related conversation. They type their email to subscribe, or, if they're logged in, it can be auto-detected so they don't retype it. Customers who would otherwise leave empty-handed opt in to a follow-up instead, and you collect the address at the point of interest, while they still care about the product.

When inventory returns

The email goes out on its own once the product is restocked. Nobody on your team has to remember who asked in chat or used the product-page button, or send anything by hand. Storefront signup, chat, email capture, and restock events end up as one follow-up path.
