A shopper wanted the size you were out of. They saw "sold out," left, and you never learned who they were or how many. The restock lands to silence, because the people who wanted it are gone and you wrote down no names.

Capture the demand before you have the stock.

Sledge puts a "Notify me" form on the product page, the product card, and the sticky variant picker, so the shopper who hits a sold-out size leaves their email instead of leaving for good. When stock returns above the threshold you set, Sledge emails them automatically. The demand that used to vanish becomes a list of buyers waiting for your restock.

A sold-out size on a Shopify product page turned into a Notify me signup.

// The list you never built

Every sold-out variant is a buyer you let walk without a word.

Whoever hits a "sold out" size isn't a browser. They came for that exact thing, in that exact size, ready to buy. The warmest demand you'll see all day, and the empty variant turns them away with no email and no count. You restock, and the only people who find out are the ones who happen to come back. Most don't.

That restock demand never has to vanish. Sledge adds a "Notify me" form on the product page, the product card, and the sticky variant picker, so the shopper who wanted size M in navy leaves their email instead of leaving without a trace. You stop losing the buyer and start building the list.

// Show it where it sells, test what works

"Will the form show to shoppers it can't actually serve?"

A "Notify me" button in front of a shopper in a country you don't ship to does more harm than good. And you won't know whether the form on the card pulls more signups than the form on the page unless you can compare them.

Sledge geo-gates the "Notify me" form so it shows where you want and stays hidden where you don't, and the whole back-in-stock setup is A/B-testable: run one version against another, split evenly per session, and keep the one that captures more signups. Show it where it sells. Keep what works.

// What plan it's on

"Is this going to be another upsell once I'm in?"

Back in Stock is included from the Accelerate plan, not as a separate add-on, and it is not on Pro or Scale. If restock alerts are the reason you're here, Accelerate is the plan that has them, alongside everything else Sledge does. No hidden tier, no per-email bill, no surprise at checkout.

// FAQ

Questions, answered

How do shoppers get notified when a product is back in stock on Shopify?

With Sledge, shoppers leave their email on a Notify me form on the product page, the card, or the variant picker, and Sledge emails them automatically when that variant returns above your inventory threshold.

Where does the Notify me form show?

On the product page, on the product card in collections, and on the sticky variant selector, so shoppers can register on whichever surface they hit the out-of-stock variant.

Does it email subscribers automatically?

Yes. Sledge emails back-in-stock subscribers automatically when stock returns above the threshold you set, with a per-customer cooldown so nobody is over-emailed.

Can I control who sees the form and test it?

Yes. The form is geo-gated so it shows to the regions you choose, and the back-in-stock setup is A/B-testable so you keep the version that captures more signups.

What plan includes Back in Stock?

Back in Stock is included from the Accelerate plan. It is not on Pro or Scale. Development stores are free, and every plan has a 14-day free trial.
