Scored on 456 merchant reviews we hold for Preorder, Back in stock Duck, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 456 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

10/10 This app was clearly made with ease of use in mind, i had a notify me button on my site less than 5 minutes after i installed it. It felt so good to accomplish something so gratifying so fast, i was even able to match our weird font! And icing on the cake, customer support is live and only moments away, like i don't think i waited a whole minute, they assured me emails will be sent automatically and offered to help me customize them if i needed.

Works well with our site, allows us to see what customers are waiting for. Emails go out when the product is available to converte to sales.

This app is great. I use it to keep a waiting list of customers who want to know when it's back in stock so I know who's interested. As soon as I update stock levels for that product in my shop, they get sent an email. I can see who's bought the product from the list. Super helpful when trying to gauge conversion stats. I purposefully waited a few months to really test it out before leaving a review. The back in stock feature works very well and as expected.

Installed the app to experiment with restock alerts. The support team was super helpful and helped me move the button to its right location. We've had some positive reactions from our customers, looking forward to working more with this!

So far, it's working well, and there's a reasonable amount of mails with the free version which means there's no worries about capacity while you're evaluating it like some others. Seems reliable and simple, which is what most people actually want.

The app is great and for the price, I'm a little blown away with the Peppyduck teams support, the best I've ever experienced! We had some unique requirements for our OOS scenario and they made it work for us pretty quickly. A small team of people with excellent support and a great product, thanks Peppyduck :)

Fantastic support experience! Tanya was quick, clear, and genuinely helpful — she had my Notify Me button positioned perfectly within minutes. Really efficient team, highly recommend this app if you need reliable customer support.

Developer repliedThank you so much for your kind words and for taking the time to leave us a review💖! I'm so happy to hear that you had a great experience with our app. If you need any help in the future we are just one ping away! Thank you again☺ - Tanya Show more

Very good service for customization, easy and comfortably set up!
