Scored on 3,432 merchant reviews we hold for Notify Me! Back in Stock Alert, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 3,432 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.

The newest 8 of 3,463. Open one to read it in full, with the developer's reply where there is one.

It is the first app to use for the purpose of preorder and whitelists, and I am overwhelmed by their great service. first, they have a package for small business that didn't pass 1-year on Shopify Second, once I requested check for eligibility of the small business package, I was welcomed and served by representative called Nilou which offered all the things that can make my website better before I am thinking of anything, everything was set up for me and adjusted to suit my website great job guys!

Developer repliedWhat a wonderful start to your Shopify journey, هَون! We built that small business package specifically for stores like yours, and knowing it's making pre-orders and wishlists accessible from day one means everything to us. Show more

Very easy to use, and support has been quick and helpful. Wish that it had support for Shopify Bundles, but very good so far!

Developer repliedWe're so glad Notify Me! has been easy to use and that our support team has been hitting the mark for you, Warrior Poet Supply Co! Your feedback on Shopify Bundles compatibility is genuinely noted — our technical team will review it soon, don't hesitate to reach out if there's anything else we can do for you! 🙌 Show more

Such a great app! Nilou was a huge help from start to finish. She responded super quickly and was really friendly throughout the whole conversation, which made the process easy and stress-free. We needed a few adjustments made, and she walked us through everything clearly and got it all sorted without any hassle. The support was genuinely top notch — responsive, patient, and focused on actually solving our problem rather than giving canned answers. It's reassuring to know that help is there and handled so well when you need it. Easy to recommend for anyone who values fast, reliable, and friendly support.

Developer repliedCenterline Athletics, hearing that Nilou made the whole process feel easy and stress-free is exactly what we aim for — patient, real support that actually solves problems. We'll make sure she knows her work is being recognized! Show more

We're currently using the restock notifications, wishlist, and low stock alert features. We will likely use the preorder feature in the future as well. We had a pile of customizations to do (mainly button placement issues) and Nilou not only got all of them done for us, but also provided a few other design suggestions around their product that were objectively the correct call, and then also got those done for us. They were of MASSIVE help - full marks to everybody on their support team that I've talked with so far. We're still in the early days of using Notify!, but at this stage I have literally zero regrets in picking this app.

Developer repliedWhat a great setup, Video Game Trader! It's awesome seeing you get real value from restock notifications, wishlists, and low stock alerts — those features work brilliantly together for a gaming inventory business. And whenever you're ready to explore pre-orders, we think you'll love how seamlessly it fits in. We're here to support you every step of the way! Show more

Miles was extremely helpful with our issue integrating Notify Me with Bundler. He gave a detailed explanation and provided several options for fixing the issue. He helped me find a Notify Me setting that would allow us to display the waitlist option on our product variants while integrating with the Bundler app.

Developer repliedWe love hearing this, Radiance Rebel! Navigating integrations between apps can get tricky, and we're so glad Miles was able to walk you through the options and land on the right solution for displaying waitlists across your product variants alongside Bundler. That kind of detailed, hands-on support is exactly what we aim for. We'll make sure Miles knows his efforts made an impression! Show more

Notify Me! is the best app after I have tried a handful of the others, quick setup, everything is simple and customizable, reasonable plan and charging model, and can't miss mentioning the excellent 5-star services provided by Nilou, she is awesome- friendly and helpful ^o^! I am happy my AI assistant recommended this app to me haha

Developer repliedWhat a wonderful review to read, 星軌 Orbitque! We're so glad Notify Me! stood out after testing multiple apps — that means a lot to us. Keeping setup simple, pricing fair, and customization flexible are things we genuinely care about. And Nilou will be thrilled to hear your kind words — she truly is awesome! We're excited to keep supporting your store. 🎉 Show more

I just started using this product, and it's amazing. The team is super responsive and I have already seen a nice impact on my sales.

Developer repliedJack, it's great to hear the impact showed up in your sales so quickly — that's exactly what we're here for. We're just getting started, and the team is always here when you need us! Show more

This app has made it so easy to add much needed features that benefit us and our customers. App customization on the seller side is a little difficult, but with a dedicated team to help code and customize to what we wanted made everything so easy. We had Miles help us make our customizations, and he did an awesome job! Recently started using this app, so only time will tell how functionable it will be for us, but the features are nice to have.

Developer repliedWhat a wonderful start to your Notify Me! journey, SAVVYCRAFT! We're so glad Miles could make the customization process smooth and stress-free — we'll be sure to pass along your kind words to him. We hear you on the seller-side customization learning curve, and we're always here to help. We're excited to grow with you and can't wait to show you what the app can do long-term! 🎉 Show more
