ZS PreSell changelog
What's new in ZS PreSell & Back In Stock.
October 2026 — Automatic back-in-stock emails
NEW
When a product comes back in stock, everyone waiting for it gets an email right away, in the language they signed up in. Shoppers waiting for a particular size or color are only emailed when that variant is back. You can switch the automatic email off on the Notify page.
October 2026 — Flow, Klaviyo and ZS Wishlist
NEW
Start Shopify Flow workflows when a shopper joins a waitlist, when restock emails go out, or when a pre-order ends. Connect Klaviyo to record waitlist activity on your customers' profiles. With ZS Wishlist installed too, shoppers see one Notify button and get one restock email.
October 2026 — Release dates
FIX
Pre-orders set to run until a release date now return the product to regular selling once the date passes, instead of only hiding the button.
October 2026 — Languages & welcome email
NEW
The storefront widget now speaks 10 languages and the admin 9, following your store's and your admin's language. New merchants get a short welcome email with the setup steps.
October 2026 — Pre-order button reliability
FIX
The app embed now always replaces Add to cart on pre-order products, and pre-orders carry a visible "Pre-order" label on the cart, checkout and order. Notify me "until quantity limit" now counts signups, and the editor won't save a campaign without its date or limit.
October 2026 — Setup in one step
IMPROVED
Turning on the ZS Pre-Order & Badges app embed is all the theme setup you need; the ZS Pre-Order block is now optional for custom placement.
October 2026 — Store data isolation
SECURITY
Campaign pages now load and change only your own store's campaigns.
August 2026 — Privacy
IMPROVED
Back-in-stock email addresses are deleted 90 days after the email is sent, or after 365 days if it never is.
July 2026 — Shopify purchase options
IMPROVED
Pre-orders use Shopify's native pre-order selling plans, so they check out like any other order.
June 2026 — First release
NEW
Pre-order, Coming soon and Notify me campaigns with countdowns, badges and a live design preview.
