We were looking for a lean way to add back-in-stock notifications to our store and connect them to our existing Klaviyo setup. This app did exactly that. Setup was simple, and the Klaviyo integration works smoothly.What stood out most was the support. When we needed changes to the template and to how the app looks in our shop, the team responded quickly and was very helpful. We got everything adjusted in a short time.We can definitely recommend this app and are looking forward to the next features!

What impressed us most wasn't just the app’s reliability, but the responsiveness of the support team. From Theme to Product to Features, the support team has always been able to help in a timely manner.
- OPOxford Pennant★★★★★
Super helpful for our store and brought in tons of revenue over the years. Helped us stop overselling while still being able to capture the sale!
- BSbohne studio★★★★★
We love Back in Stock. It was easy to add to our custom theme and the notify me button blends right in where add to cart sits, in our own fonts and colors. Customers can sign up for the exact color and size they're waiting for, so a sold out item no longer means a lost sale for us. A lovely, well built app and a great fit for a small brand like ours.
About ShopDigest
The Shopify ecosystem, shown through the work
ShopDigest is an independent directory of Shopify work. Developers, agencies and experts publish the projects they’ve actually shipped — migrations, rebuilds, custom apps, headless storefronts — with the results attached.
For merchants, that means judging a partner on evidence instead of a sales page: browse real builds in your category and budget, then reach out directly. For builders, it means one profile that keeps working after the project ships.
No commissions, no pay-to-rank placements. The best work rises because people save and follow it.
