Shopify app
Design the offer, set the percent, and send a one-use code when someone signs up. Recommendations use the product and the cart, not a shopper’s name or email.

Castor
Offers, popups, and the product desk.
01
Install from Admin. The catalog, the theme, and the discount codes stay on that store.
02
Start from the gallery or draw a popup, bar, or widget. You set the percent and the free-shipping amount.
03
Store sales stay next to the revenue attributed to the popup or widget that the shopper used.
Signups sit on that store’s contact list. They are not used to recommend products and they are not shared with other stores.
A form set to Generate creates a one-use Shopify code at the percent you chose and shows it after Send.
Popups and widgets run from the theme app embed. The product desk pulls and sends the catalog you already have in Shopify.
