Stoq: Back In Stock, PreOrder

The app is easy to install, navigate and the most cost-effective app amongst similar products! Simple management console without compromise on functionality!! All the metrics can be get with a glance!! And it works perfectly on Atlantic template. The app owner is super helpful, he responded us immediately during weekend and fixing the issue we faced within 12 hours.

A+++ customer service / support, truly impressive. The app functions seamlessly and gets the job done. Its easy to use and was quick and easy install and set up. Would highly recommend.

A must have APP!! I left writing a review until I could see it working fully, right up to the point of re-stocking/customer contact/customer orders, and it works brilliantly. Within minutes of re-stocking I could see the auto-generated emails being sent to registered customer and on the very same day we had orders off the back of the notifications.
So easy to install, and the customer service, however small your query, is how every company should react to customers; helpful, willing and quick.

Perfect so far. Kartik, the designer was most helpful in the setup in every way. The look is good and the test notifications have been sent. Still early, but expect nothing but great things from this app. Thanks, Gene @ Anni Lyn Sportswear, LLC

They are a small team of 3 working full time on building Shopify apps & supporting merchants.

The live chat support was fantastic. They respond quickly and had no problem resolving issues I had with customizing the button and pop up to match my theme.

INSTALL THIS APP.
Wish I could give more than 5 stars! Our theme was automatically inserting an out of stock form with nearly no functionality...it only sent us email notifications which required us to manually respond to when back in stock... (that's not good enough!) We wanted something automated and found Restock Rocket... It offers powerful features, extensive customization options, and the back in stock notification emails come from YOU, not a third party server, so it's far less likely to land in your customer's spam folder. The developer is a one-man team: Kartik. I don't think he even sleeps! We did have a few questions that we submitted at odd hours, and he always responded within seconds (not an exaggeration... he is so nice, knowledgeable, and helpful). I cannot recommend highly enough!!! INSTALL THIS APP. PS if your theme automatically inserts its own out of stock form that you need to disable, this link was how we turned ours off... yours might have a similar switch to turn it off so that the Restock Rocket app takes over.

Great app! Super easy to use, styling is great and the customer service is excellent. Highly recommend!

What is ideal about this app is having both SMS and Email fields in the same sign-up widget. Thank you Kartik for your support, especially on a Sunday!

This app is fantastic. Within an hour after installation, I had already received several sign ups for back in stock notifications. AMAZING!!! The app has some great features which allows you to customise messages, buttons etc. to fit in with your brand look, feel and tone of voice. The app was easy to install, Kartik was on hand to give assistance if needed. The customer service was professional and prompt. You can be up and running within minutes with this app with no coding required, which was a HUGE PLUS. Did I mention this app is free? Yes all this is free! If you need a no-fuss restock app, don't bother to look any further. This is it!

Very good Product support, very easy to use and pleasing interface :)
