Cart Alarm: Add to Cart Alerts launched on October 20, 2026. Shoplist is watching for its first storefront installs and tracking pricing in the meantime.
Get an email when shoppers can't add to cart, so you can fix it before it costs a day of sales.
A theme edit, an app update or a new script can break Add to Cart without any warning. Orders slow down and nothing tells you why. Cart Alarm watches each Add to Cart try on your storefront and checks that the item reached the cart. It first learns what a normal day looks like for your store. After that it emails you when tries fail far more often than usual, and again when adds are working. There is nothing to set up. It watches Add to Cart only and needs a theme with a standard product form.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Cart Alarm: Add to Cart Alerts on a store, it is there.
