**Short answer:** Plan the sellout before the launch: a waitlist that captures variant-level intent, a first-minute guide that gets shoppers to their variant, and a restock message that is specific about when and how much. Release back-in-stock alerts in batches sized to stock, oldest sign-ups first, and stop at zero. A sellout that leaves no plan behind is a launch that failed at the finish line.

## The waitlist is the launch

The launch sells out in the first hour. The store celebrates, and then the emails start: shoppers who missed it, shoppers who wanted a size that never existed, shoppers who joined the waitlist and heard nothing. A sellout is a merchandising success and a customer-service problem at the same time, and the difference between the two is whether the store planned the sellout before the launch.

The plan starts with the waitlist. A waitlist that captures variant-level intent, which size and which color each shopper wants, is worth more than a waitlist that captures email addresses, because it tells the store what to restock and who to tell first.

The waitlist is also the demand signal. A launch with 2,000 people waiting for 150 pairs is not a launch that failed. It is a launch that proved demand, and the proof is useful only if the store uses it: to size the restock, to price the next run, and to tell the waitlist the truth about when more is coming.

## The first minute decides the variant

The shopper who cannot find their variant in the first minute buys the wrong one or buys nothing, and the wrong variant is a return. The launch page has to guide shoppers to their variant immediately: the size guide on the page, the color swatch that looks like the product, and the variant that is actually in stock marked as such.

The add-to-cart button has to be where the shopper expects it, and it has to say something the shopper understands. [The add-to-cart button nobody clicks](https://keenmerch.com/blog/2026-11-10-add-to-cart-button-placement-copy/) loses the sale in the first minute, and the sellout that follows is a sellout of the wrong variants.

The variant cap matters here. Shopify now allows 2,048 variants per product, raised from 100 on October 15, 2025, with a 3-option ceiling, but themes render only about 250 variants, so a launch with more variants than the theme can show is a launch that hides its own inventory.

## The sellout message is a promise, not an apology

The launch message should plan the sellout moment: what happens when it sells out, what the shopper should do next, and when they will hear from the store. A message that says "sold out, sorry" is an apology. A message that says "sold out, the restock lands Tuesday, and you are first in line" is a promise, and the promise is what keeps the shopper.

Be specific about restocks. A shopper who hears "soon" stops checking. A shopper who hears "Tuesday, 10 a.m., 150 pairs" sets an alarm. The specificity is the retention.

## The restock, in batches, oldest first

Release back-in-stock alerts in batches sized to stock, oldest sign-ups first, and stop at zero. Two thousand people waiting for 150 pairs means 150 people get the alert and 1,850 do not, and the 150 who get it should be the ones who waited longest.

The cart drawer is the upsell slot for the restock. [The cart drawer is your best upsell slot](https://keenmerch.com/blog/2026-11-09-cart-drawer-upsell-slot/), and the shopper who comes back for the restock is the shopper most likely to add one more thing.

## Frequently asked questions

### What should I do first when a launch sells out?

Tell the waitlist the truth: when the restock lands and how much is coming. Release back-in-stock alerts in batches sized to stock, oldest sign-ups first, and stop at zero. A specific restock date keeps shoppers; "soon" loses them.

### How many variants can a Shopify product have?

Shopify now allows 2,048 variants per product, raised from 100 on October 15, 2025, with a 3-option ceiling. Themes render only about 250 variants, so the theme is the real ceiling, not the platform limit.

### Why does variant-level intent matter on a waitlist?

Because it tells the store what to restock and who to tell first. A waitlist that captures which size and color each shopper wants is worth more than one that captures email addresses alone.

### What should the sellout message say?

What happens next, and when. Plan the sellout moment in the launch message: the restock date, the quantity, and the shopper's place in line. A promise keeps the shopper; an apology does not.
