Handles both price drop alerts and back in stock alerts. Finding an app that does price drop alerts without requiring the customer to log into a store account was difficult.

A well-built and reliable app for restock and sale notifications. Setup is straightforward, customization options are excellent, and the dashboard provides clear insights into subscribers and performance. It has helped us recover lost sales and reduce customer inquiries. Support is professional and responsive. Highly recommended for serious Shopify merchants.

Love this app. I was looking for an app to do restock emails but all the other apps had no freedom in design. Kudos to the team who built it. Great support also.

Developer did an amazing job. I was looking for something to notify my customers who abandoned their sales due to out of stock products and this app works like a charm and very easy to setup with affordable rates and great support. Kudos to the developers. 10/10 for the app. Keep up the work.
