Notify Me review

What Notify Me actually does

Notify Me is a Shopify app that addresses one leak: traffic arriving at a product that cannot be bought. Instead of a sold-out button, the product page offers to take the shopper's contact details, and when inventory returns the app sends a notification with a direct link back to the item. Around that core it adds three related mechanics, pre-orders for stock that has not landed, wishlists for products someone wants but is not ready to buy, and low-stock badges that show how few units remain.

The delivery side is deliberately broad. Alerts can go by email, SMS, push notification or WhatsApp, with the messaging channels billed on usage at country rates rather than bundled into the subscription. Collected contacts can sync into Klaviyo, Mailchimp or Omnisend on the higher plans, so a restock signup becomes a marketable subscriber rather than a dead end. Installation is a Shopify app install with theme placement handled by the app, and billing runs through the Shopify invoice. The vendor reports use by more than thirty-five thousand stores, and the app holds a rating close to five stars across several thousand Shopify reviews.

Key features

The four mechanics share one contact list and one notification queue:

• Back-in-stock alerts fired by inventory returning, with a notify button in place of the sold-out state
• Pre-orders supporting partial payment, discounts and per-variant availability dates
• Wishlists that work for guests as well as account holders, including price-drop alerts
• Low-stock badges showing remaining units on the product page
• Email, SMS, push and WhatsApp delivery from a single queue
• Contact sync into Klaviyo, Mailchimp and Omnisend on the upper tiers

Who it's for

The merchants who gain most are those whose bestsellers sell out: apparel brands with limited runs, supplement and beauty stores waiting on production, anyone whose supply chain is slower than demand. For them the wishlist and restock data is also a demand-planning signal, showing which variants people asked for before the next order is placed. The free tier is small but real, so a store can measure the size of the leak before paying to fix it.

Stores that rarely run out of stock will get little from the restock half and should judge the app on wishlists and pre-orders alone, which is a narrower case than the pricing assumes. The plan structure also punishes spiky demand, because the notification allowance is a hard monthly cap rather than an overage: a single viral restock can exhaust a tier mid-month and pause sending until the next cycle. And because this is a Shopify app, none of it helps a merchant on another platform.

How it compares

Back in Stock by Swym and Restock Rocket cover the alert use case with similar competence, and Swym has a longer track record on wishlists; neither bundles pre-orders as thoroughly. Dedicated pre-order apps such as PreProduct or Amai handle deposits and staged payments in more depth, but do nothing about restock demand. Klaviyo itself sends back-in-stock emails perfectly well, and a store already paying for Klaviyo should weigh that native flow against another subscription, though Klaviyo will not run pre-orders, wishlists or stock badges. Notify Me's argument is consolidation: one app, one contact list, four mechanics that all deal with inventory a shopper cannot buy today.

Verdict

As a bundle this is well judged. Each of the four features exists elsewhere, but running them separately means four apps, four theme integrations and four contact lists that never reconcile. The channel spread is unusually wide for the category, and the wishlist data is more useful for buying decisions than merchants expect. The caveats are commercial rather than technical: allowances are hard caps, the messaging channels are metered on top of the plan, and the Klaviyo sync that serious stores depend on is reserved for the more expensive tiers, which is where the real cost of the app tends to settle.
