It's not 5 stars because there was a hiccup after couple of months using the app. I installed the app because of the Free plan, spent time getting it running, and then the free tier was cut and my back-in-stock emails stopped until I upgrade to paid plan. It was dissapointing to say at least, and quite stressful. But, they stepped up, admitted it was a wrong direction to go as a company, and m...

We spent quite some time looking for a BiS app that would meet our needs. Xflow is an absolute perfect fit for us. The app is constantly being improved; you can contact the developers at any time, get a response very quickly, and we’ve always received competent and prompt assistance with all our concerns. So we highly recommend it :)

great product and customer service!

The Xflow app really boosts your back-in-stock program with its templates and workflows. I'm actually excited to focus on a feature that I never would before because I didn't think I could tailor it this much to my business. I can't wait to see how it performs once I put it into action. Zuri has been very friendly and helping me with customizing the look of the "Notify me" button and sign-up form....

Linh and the team is very responsive and resolved a small issue we have been facing. The app is super intuitive and the Shopify Flow integration opens up a whole lot of opportunities. Highly recommended!
— Life Apparel Co
Setup help from the team was good, no complaints there. The problem is the business model: I installed this because of the Free plan, spent time getting it running, and then the free tier was cut and my back-in-stock emails stopped until I upgrade. That's not a free plan, that's a trial with extra steps. I'd suggest looking for an app that is upfront about its pricing from day one.

Great experience with XFlow. The team is professional, responsive, and always helpful. Communication has been smooth throughout the entire process. Highly recommended!
— NUSOS
This app has made managing back-in-stock notifications much easier for our store. Setting up the notification button and automated alerts was straightforward, and I like that the emails can be customized to match our branding. The ability to see which products customers are waiting for is also really useful for understanding demand and planning inventory. The analytics give us a good overview of h...

Finally, a professional grade app with professional support to back it up. I have never received the level of support I've experienced with this app in any other I've tried; they seem to be around almost 24x7 and most issues I've raised get solved on-the-fly by their support team with direct integration to your store. It does exactly what is says it will and is being actively developed with commun...

Great app. Helps a lot with restock campaigns.
— Secotécnica
XFlow was super easy to get set up and works exactly how we need it to! One of their team members (Linh) reached out to help us with some formatting which was super appreciated! Great app!
— Into The Wind Kites
Such a great app, great features, and amazing support, they are so quick to help when you have issues or questions!
— Office Human
The widget looks great on the product page, the analytics are solid, and the email templates that come out of the box are fantastic, there's a good range to choose from without needing to build anything ourselves. We've had the pleasure of working with the app developers on a number of projects, and they've been excellent every time - quick to respond and genuinely helpful.
