Stop losing sales when inventory runs out

Featured on a blog? Cracked that Adwords campaign? Your store can see a surge of visitors in moments. Awesome! But what if your inventory sells out?

Don’t lose sales when your inventory runs out. Back in Stock makes it easy for customers to sign up for a back in stock email alert. When you restock products the waiting customers are emailed automatically to bring them back to your store and complete the purchase.

It’s simple to setup and runs automatically.

Measure demand, not just sales

It’s something every store owner needs to know: what items do my customers most want to buy? We can help.

Use the Back in Stock dashboard to immediately see what items customers want to buy. Or receive daily or weekly reports about which items are most in demand and the quantity you need to order.

Increase your profits by knowing rather than guessing what customers want.

Simple setup

Installation takes less than 30 seconds. Simply hit Get App and a button saying ‘email me when available’ will immediately appear on all relevant product pages.

This button automatically connects to a Back in Stock pop-up form that has a field for email address and a drop-down menu for product variants.

There’s no need to edit an email template or pay for tech support. Simple!

Effortlessly scalable

Back in Stock regularly sends out about half a million emails a month – we can handle volume.

You don’t need to do anything special if you’re a large store installing the app. Just feel confident that it will work at scale and that it will continue to work in the future.

Powerful customization

Although our default button and pop-up form convert well, we appreciate that you want them to integrate seamlessly with your store. We make this as easy as possible. You can:

  1. Use your own custom button image (any image in PNG, JPEG or GIF format can be used)

  2. Change the copy on the pop-up form (particularly important if your audience are not English speakers!)

  3. Change the design of your pop-up form using CSS

  4. Superpower the back in stock form provided by Mobillia, Responsive, Retina and Parallax themes with our one-click install process

  5. Get customers to opt in to your mailing list at the same time they enter their email address if you use MailChimp, Campaign Monitor, Klaviyo, or Constant Contact

  6. Create custom integrations if you are a developer using our Javascript API

Super fast email delivery

About 60 seconds after you update your catalogue, your customers will receive an automatic email alert telling them that the item they want is back in stock.

This means that if you are running a sale, or simply sell and restock quickly, then you should see a much higher conversion rate. Time is money!

Super friendly and experienced support

If you’ve got questions, before or after installation, just drop an email to support@backinstock.org. We’ll get back to you quickly by email, and we won’t use tech language unless you do.

Back in Stock is created by Yellow Robot. We’ve been in business since 2009, and we specialise in providing apps for Shopify users. We’re not going to disappear or leave our app to become outdated or insecure.

If you’re looking for a scalable, stable and supported app you can rely on us.

Really useful app that allows us to let customers know when products they are interested in are back in stock - has led to more sales!


Outstanding app and even better customer service. Far and away one of the most useful and reliable tools in the entire app store. A must-have for any store owner.


Awesome app helps you keep track of customers who are looking for products that are out of stock!


Very good experience automating something we used to do (in part) manually. No complaints.


Great app, well supported with quick response time and regular feature updates.


Brilliant app, awesome support.


Brilliant App, extremely easy to use.
We would highly recommend to any Shopify store owner.


We've been using this app for couple of months now and loving it. Though we always keep our inventory well and almost never run out of stock but when we do, this app really helps. Very simple but does the job done!


Great App! Love it! Works like a charm and helps me decide what to build. Thank you!!


This app is amazing for two reasons:

1) It delivers exactly what it promises, with a sufficient level of customization and control. Customers sign up, when product arrives, the emails go out without a hitch, and it only sends an amount relative to the stock I have. I just upgraded for the second time, because we are getting more and more use out of it.

2) No upkeep. I did some minor customization to the form, but since then it has been entirely on autopilot and working flawlessly.

If every other app filled it's purpose as amazingly as this one, my store would practically run itself.
