CartCode Back in Stock shows an email sign-up only when a shopper picks a sold-out size or color. When the item is restocked, each shopper gets a single email, in sign-up order, in the language they browsed in (English or Japanese). Stock is re-checked right before sending, in the shopper’s market, so no email goes out for an item that sold out again. Emails go out in your store’s name with a one-click unsubscribe. See who is waiting, the send history and link clicks, and export sign-ups as CSV.
