Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCartAI Upsell helps merchants suggest one relevant accessory after a customer completes a paid order. The app reads order line items, applies the merchant’s accessory catalog settings, writes a short plain-text email in the chosen assistant tone, creates a Shopify draft order with combined shipping, and logs each send for review and attribution.
RetainAI bundles three retention engines for small Shopify stores: AI-written abandoned cart recovery, post-purchase review request emails, and one-click loyalty with auto-issued Shopify discount codes. Built for stores that would otherwise install three separate apps for these jobs. Every recovery email is written by Claude AI using the customer's name and the line items in their cart.
- Generate AI accessory recommendations based on paid order line items
- Send combined-shipping draft order links directly to customer emails
