Heartscrip review for REZ Preorder, Back In Stock

May 22, 2026

Absolutely amazing app! The preorder and back-in-stock features work flawlessly and will help me recover so many potential lost sales. Super easy to set up, clean design, and the customer notification system works perfectly. Emma is also incredibly fast, friendly, and genuinely helpful whenever I need assistance. Highly recommend this app to any Shopify store looking to boost conversions and manage sold-out products professionally!
