Shopify gives a variant one lever when stock runs out, and it is a switch rather than a feature: customers can keep buying it, or they cannot. Choose the second and the storefront simply refuses, with nowhere for a shopper who still wants the thing to leave their name. There is no waitlist object in Shopify and no per-product signup; the only native way to collect an address with marketing consent is the theme's newsletter form, which knows nothing about which product somebody was looking at.

These apps fill that in, and what they collect is worth as much as what they send. A waitlist is a demand list: it tells you which variant, in which size, how many people and for how long, which is the one piece of information a stockout otherwise destroys. Expect the same listings to also offer preorder, because Shopify's own feature tags place the two side by side, and be clear which you want. An alert asks the shopper to come back later. A preorder takes their money now.

What to look for in a Notify Me app

Which restock actually triggers the message: The event these apps listen for is fired when a variant comes back into stock, and Shopify's own documentation notes that online channels are notified when the variant becomes available online. If your stock moves between locations, arrives through point of sale, or sits at a warehouse you do not sell from, ask specifically what counts as back in stock before the emails go out.
Variant precision: Somebody waiting for the medium in black does not want to hear that the small in white arrived. The alert has to be tied to the variant that was clicked, and the signup button has to follow the variant picker rather than sitting on the product.
Email, text, and whose consent it is: A back-in-stock alert is a message somebody asked for about one product, which is not the same as permission to add them to a newsletter. Check what the signup records, whether the address flows into your marketing list, and whether that is presented honestly to the shopper. Text messages raise the same question with a higher price attached.
What you can read back: The reporting is the underrated half. Signups per variant, over time, tell you what to reorder and how much, and that number is worth more than the recovered sales the alert itself produces.
Whether the answer is preorder instead: If the stock is genuinely coming, taking the order now removes the second visit and the race to the button. That is a different setup with different money in it, and many of these listings sell both, so it is worth deciding before you install rather than after.
