The easiest way to increase sales from your existing traffic

You’ve invested valuable time and money getting customers to your website. Don’t lose out on a sale because the item they want to buy has just sold out. Back in Stock makes it easy for customers to quickly sign up for a back in stock email alert.

The moment an item is available, your customer is automatically sent an email with a buy now button. You’ve made an extra sale, plus your customer is left with a good impression of your store, rather than a bad taste in their mouth because they couldn’t buy what they wanted.

“I can’t tell you how excited I am to have installed this app. It’s tripled my online sales… easy!” Laci, shoptherage.com

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, Parallax and Woodie 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.

Exactly what I was looking for! My theme required some customization, support fixed it exactly how I wanted very quickly! Highly recommend this app. Amazing support!


If you're looking for a no-frills (in a good way), highly-customizable Back in Stock app for your Shopify store with a great support team - this is it.

We were doing all of our back in stock notifications manually which was obviously a nightmare. This app automatically emails your customers who have filled out the back in stock form (which we were able to seamlessly integrate into our product page) whenever you adjust the quantity of your inventory. We were able to customize the email to match our current branding and the support team even helped us exclude some products (sale, vintage, etc.) from displaying the button.

We are seeing a great response from our orders and our analytics so far and the workload is literally gone. Thank you!!!


We tried a bunch of in-stock apps and found this one to be significantly more mature. Adding it to the site was a snap, and our customers started using it immediately.

For us, this easily pays for itself every month based solely on the reduction in support requests.


The app is very easy to set up and use. It is incredibly simple for customers to understand how to use it.

We have thousands of T-Shirts and sometimes a particular variant is out of stock but the other sizes are in stock. The app was only showing items that were out of stock for all variants.

We reached out to Matt about setting up an out of stock for one size of a T-shirt. He responded incredibly fast! I sent an email at 2:09pm he responded by 2:17pm.

We exchanged a few emails and by 4:37pm he had the code integrated into the site for us.

AMAZING Customer support. He offered great suggestions. If you are looking for an out of stock app pay your money to Back in Stock and call it a day you will not regret it.


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.
