This blog is your guide to smarter inventory alerts. Let’s go!
What is a Shopify Restock Alert App?
A Shopify Restock Alert App is a nifty little app that gets added to your store! It adds a “Notify Me” button to products that are out of stock. When you restock, it integrates with your stores and sends an email or text to the customer automatically! No more manually following up! Just that easy!
Think of it kinda like a friendly reminder service. Customers love it because they won’t miss out! And you love it because it captures a sale. In 2025, as e-commerce in the US is 5% up, we are seeing some of these same bumps despite the trade hiccups. These types of apps will surely become standard for busy owners.
Stores that used a low-stock warning saw 5.3% more revenue from each customer! It’s not magic, just smart technology fixing a big pain point. (Source)
Why Do You Need a Restock Alert App for Your Shopify Store?
If you are running a Shopify store in 2025, you are going to have a fast sale cycle, and any hot deals will sell out in just a few hours. Stockouts will kill that momentum. 69% of buyers bounce if one item is out of stock, and that adds up to a lot of money around the world.
There is a need for information: without alerts, you’re missing repeat buyers. A Shopify Restock Alert App will keep those buyers engaged. It will allow the buyer to put themselves on a waitlist, and when you receive more stock, the sales will follow. Think of a clothing shop that sells a viral jacket: it sells out, and alerts get sent out to 200 waitlisters, and bam! 50 extra orders overnight!
The data suggests there is a gap: E-commerce grossed 1.29 trillion dollars in the US alone. Poor inventory management is a big issue, like anything else, and alerts can recapture some inventory. This is especially true if you drop ship, are selling seasonal goods, or are in a high-demand niche. (Source)
In summary, stockouts can be painful, but adding an alert to your store is just an easy safety net away. Alerts can restore a frustrating shopping experience into a loyal customer, one alert at a time.
