A customer visits your store, finds the product they want, sees "out of stock," and leaves. Most of them never come back. Notify Me turns that dead end into a recovery opportunity. Customers sign up for notifications on out-of-stock products, and when inventory returns, they get an email, SMS, or push notification within minutes. Back-in-stock emails typically see 30-50% open rates because the recipient already told you they want the product.
Start Recovering Lost SalesHow It Works
Install Notify Me on your Shopify, WooCommerce, or other e-commerce platform. Out-of-stock product pages automatically show a "Notify me when available" button. Customers enter their email (or phone number for SMS). When you restock, notifications fire automatically. The customer clicks through and buys.
It works at the variant level. A customer who wants a size Medium in Blue gets notified when that specific variant restocks, not when an unrelated size comes back.
Beyond back-in-stock, Notify Me also handles price drop alerts (notify when a product they viewed goes on sale) and pre-launch waitlists for new products or limited releases. The demand analytics dashboard shows which out-of-stock items have the most waiting customers, which directly informs your purchasing decisions.
Try Notify Me FreePricing
Starter: From $32/month (~€29). Up to 1,000 notifications per month.
Growth: From $87/month (~€79). Higher volumes, additional features.
Scale: From $219/month (~€199). High-volume stores with advanced needs.

SMS notifications cost extra per message on top of the subscription. At $32/month, you need the recovered revenue from a handful of sales to justify the cost. For stores with popular items that regularly sell out, the math works easily.
Strengths and Limitations
Strengths:
- Recovers sales you'd otherwise lose completely
- Multi-channel (email, SMS, web push, app push) increases the chance customers see the notification in time
- Demand data helps you make better restocking decisions
- Variant-level tracking means customers get relevant notifications, not noise
Limitations:
- Only valuable if you actually have stockouts. If your inventory is always available, there's nothing to notify about.
- SMS costs add up at scale. Per-message fees on top of the subscription can get pricey.
- Conversion isn't guaranteed. By the time you restock, some customers have bought from a competitor.
- Small stores with low traffic may not generate enough signups to justify the monthly cost.
Notify Me vs. Klaviyo vs. Shopify Back in Stock
Shopify Back in Stock apps (free or cheap): Basic email notifications when items restock. Fine for simple use cases, but no SMS, no push, no demand analytics, no price drop alerts.
Klaviyo: Includes back-in-stock flows as part of its broader email platform. If you're already on Klaviyo, you may not need Notify Me for basic restock emails. But Notify Me goes deeper: SMS, push, waitlists, demand analytics, and price drop features that Klaviyo doesn't focus on.
FAQ
How fast do notifications send after restock?
Within minutes of inventory becoming available. Speed matters because popular items may sell out again quickly.
Does it work for specific sizes/colors?
Yes. Customers sign up for specific variants (size Medium, color Blue), and only get notified when that exact variant restocks.
Notify Me is a focused tool for a specific problem: turning stockouts from lost sales into recovered revenue. If your store regularly sells out of popular items and you're not capturing that demand, you're leaving money on the table. The multi-channel notifications, variant-level tracking, and demand analytics make it more than a basic "email when back in stock" widget. Whether it's worth $32-219/month depends on how often you run out and how much a recovered sale is worth to you.
