How do back-in-stock emails work?

When a variant reaches your restock threshold, Simple Chat sends restock emails to its waitlist, subject to any send cap you've set. Signups from the product page and chat use the same variant waitlist.

Enabling restock emails

1. Open Email settings and complete sender verification.
2. Turn on Enable back-in-stock notifications.
3. Set the email subject and template.
4. Choose the Restock threshold.
5. Set a Send cap multiplier if you want to limit how many people are emailed per restock.

The threshold is the inventory quantity a variant must reach before alerts go out. A customer waiting for a medium blue shirt subscribes to that variant; restocking another size or color doesn't notify them.

The optional send cap limits emails by stock quantity. For example, a multiplier of 4 with 10 units in stock allows up to 40 emails. Leave it empty for no cap.

Signing up and testing

You can add the notify-me control so customers can subscribe from the product page without opening chat. They can also ask for an alert in the conversation.

To check the setup, use an out-of-stock test variant, subscribe with an email you can access, and confirm the signup. When that variant is restocked to your threshold, check the message and its product link.

If no email arrives, check that notifications are enabled, the sender is verified, and the correct variant reached the threshold. Also check whether a send cap limits that restock's emails.
