Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCartnio emails each customer a one-time review link after fulfilment, so reviews come from real buyers and carry a Verified buyer badge. Customers can add photos and videos, and you approve every review. Shoppers can ask product questions. Add reviews, Q&A and star ratings with theme blocks.
Trio replaces three separate apps with one. Collect product reviews with photos, send email campaigns and automations, and run a loyalty system with points, VIP tiers, and referrals. Everything works together natively: customers earn loyalty points for leaving reviews, VIP tier changes trigger automated emails, and you can segment email campaigns by loyalty status.
- Review requests emailed automatically after each order is fulfilled
- Verified buyer badges, photo and video reviews, and product Q&A
- Theme blocks for reviews, Q&A, star ratings and review carousels
- Collect photo reviews automatically after delivery with smart timing
- Send email campaigns and 8 automations including abandoned cart recovery
- Run a points and rewards system with VIP tiers and referrals
- Award loyalty points for reviews and send tier-up emails automatically
