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.

Love this app for multiple reasons! Firstly, the customer service is amazing. Matt reached out immediately when we needed help and even assisted us with coding so that the app worked seamlessly with our site. Secondly, this app provides valuable data for figuring out who your customer is and what's missing from your store (even if you don't ever restock items). Totally recommend!!


This app saves you a lot of time if you have products that sell out quickly. Customers really appreciate being notified when the product they want is back in stock and this app delivers great looking emails.


We just installed this app and we ran into a couple integration issues as we wanted to customize the button and the popup window. Support was very fast and unbelievably helpful. They state support within one business day but we were pleasantly surprised to find it's typically much faster. Everything has been integrated nicely now and we are off and running. It's all about customer support and these guys have nailed it. Not to mention it is a great product that does everything we needed and more.


I previously had to build lists from emails that the site generated for each product, and then build a separate notification email for each one that came back in stock. Ahh! So it's magical that it's all happening automatically now with the Back in Stock app. It's been a huge timesaver, and I really appreciate that it gave us full control over our email creative, and also integrated beautifully into our site's theme with one click. Additionally, Matt has been really helpful in responding to the questions I've had during setup.


We've sent hundreds of emails w/ Back in Stock. We've seen a noticeable boost in sales when the emails go out. A must have App for your store.


We have installed Back in Stock in two of our Shopify Stores (Pacific Northwest Gifts and Portland Mercantile Company). Matt helped us with the install and he did a great job.

I would not hesitate to recommend this app to anyone. It is easy to install, there is superb support, and you will get results.

Great app, and the team is super helpful! They implemented a more custom design and allowed the Back In Stock Email Notification to show up for a single size that was out of stock as opposed to showing up on the entire product page. It has helped increase sales and keeps our customers coming back to get the products they love. The app emails the customers for you, so no need to worry about that, and you can see which products/sizes are most in demand, which is helpful for inventory management and restocking. You need this app for your online store! Thanks Matt for all your help!

Back in Stock has unequivocally changed the way we do business at Painted Fox. Matt has been able to custom design the app to specifically suit our needs. He is smart, attentive, responsive, and professional. Simply stated, their customer service is unmatched and the app itself is a game changer. We would recommend it without any hesitation!

The app works perfectly in capturing interest in a sold out product. Using this app can provide a great boost once you re add inventory. The support staff (Matt) is amazing. Anytime we have changed themes or wanted help he took care of it right away. You can't go wrong with this app and Matt.


Excellent app! Support was great in getting the app customized to our template and it looks completely seamless with the site design unlike some of the other apps that do the same thing. Other positives include easy to use back-end interface, and nice customization options on the e-mail notifications. This app is a must for a any store that loses sales from out of stock products.
