What merchants think

Feedback submitted

Merchants highly recommend this app for stores that frequently sell out or run limited inventory. They report clear sales boosts from back‑in‑stock emails and SMS, plus easy waitlists that automatically notify shoppers and save time. Demand tracking by product and variant helps with restocking decisions, even for large catalogs. Setup is simple, customization is flexible, integrations are useful, and support is consistently fast, proactive, and hands‑on.

So far my biggest experience was the app not properly communicating with our theme. However, the app support team quickly changed it for us and made sure it was working. They also added it to some of our other types of products that would be great matches for the functionality. We are really looking forward to see how well the app works with our customers. Will keep you updated!

Do not install this app unless you want a ton of unhappy customers. This app worked great for a few months until it started sending out tons of back in stock alerts for products that were still out of stock! It's done this with over 20 products in the last 3 weeks. I finally deleted it. There were no returns for these items and the inventory had not been altered at all. NOT HAPPY

Thank you for taking the time to review our app. We understand it’s frustrating when your customer receives a back-in-stock alert for a product that was not restocked and they were unhappy about it.

With that said, At Swym we always own a merchant problem and provide a timely solution and it’s painful to know that we haven’t been able to deliver that value to you.

Our app is designed to collect subscriptions for Sold-out products and trigger the alerts only when we receive a product update from Shopify for these subscriptions. This is generally true of all the back-in-stock apps in the Shopify AppStore. We completed a thorough investigation of the issue you reported to see why those emails were triggered.

For the period from October 19-21, a total of 20 alerts were sent by the app across 6 different products. Our app triggers alert based on 2 events:

1. A shopper signs up for an alert on an out-of-stock product
2. We receive an update from Shopify that tells us a product is in-stock.

Only when these 2 events occur in combination can an alert get triggered. In every single one of the cases where alerts were sent for your store, we’ve verified that both these events happened. However, the issue seems to be that the first event, i.e. a shopper signing up for a back-in-stock alert was able to do so even when the product was actually in stock according to Shopify - indicating that the product-detail page was showing the product as Sold Out for that particular variant.

This can occasionally happen depending on your theme settings but because the app had been uninstalled, we were not able to validate this. It is only with the data we are piecing together from our logs that we were able to conclude that. We have shared our findings and logs on the support request you opened, please check and let us know if you’d like more information. Even if you choose not to reinstall our app, we’d like to help you get to the bottom of this issue and help resolve it for you because it will likely cause other related issues for you.

This app works a treat to notify customers when products are back in stock via email. We generate a lot of sales through the app and can see as soon as a garment is listed in stock traffic rushes to the site. We had an issue with it synching with a new shopify store template but customer service immediately fixed the problem for us within 10 minutes of contact. Great customer service

Update: I switched themes on my site, so the app got lost. Sent an email and it was fixed within 24hours! Thanks, Sonali! Installation and customization was a piece of cake! However, I needed the alert to show up as soon as a single size was out of stock, rather than when the product was out of stock in every size. I emailed support, and presto! Krishnan was swift, polite, and effective.

This app is very clean and customizable. customer support is A+ our theme didn't support one aspect of the app and theme support wouldn't help so app support jumped in and fixed it over night with very good communication. would purchase another app from them and would recommend to anyone who needs quick smart app support, and doesn't have time for the run around with email chains. great app!

Very positive experience with the support!
I installed the app and wasn't satisfied how it worked with our theme. So I reached out to support and frankly I wasn't expecting that the issues could be modified, but still gave it a go. Support took over and all my needs were met quickly and the app is up and running and we are right away getting more 'alert requests' than even anticipated!

Two thumbs up!

This is the perfect app for automating the entire process of notifying your customers when a product they’ve been waiting for is back in stock. It’s super easy to customize the layout & emails from the dashboard, and the developers are extremely helpful with setting it up so it fits your theme and have always responded in a timely manner to any questions/concerns. Highly recommended!

I can't talk up this app up enough, and especially the Support Team. Great support, top notch! Highly recommend. We have changed themes a few times, and along the way, they have always been there to update what needs to be changed, and even did something for us that they don't show that's possible in the app! Great company, and the sales from this app is noticeable. Thank you guys for always being there.

We had some initial trouble getting the app to work due to some compatibility issues with the theme we were using, but the development team was very responsive and extraordinary in making the necessary adjustments to make it work! The dashboard gives you a control tower view of all of the stock alerts that customers have requested. The app also provides a wonderful new data source of where we should focusing our efforts!

Easy set up and amazing customer service. I was a little worried when I saw some of the things I wanted didn't seem to be out of the box. But the support team literally had all my requests answered in only a few hours (including changing font sizes, integrating with Klaviyo, and setting a threshold for sending alerts). It's been on my site for 24 hours and I have already collected 23 new customer emails! Super happy so far.
