# Back-in-stock demand left waiting

> Back-in-stock requests go unanswered when the flow is off, in draft, or not tied to restocked items. Connect Klaviyo and Shopify to Claude and ask it to match every request to products now in stock, count waiting shoppers per product, and confirm whether they were emailed. Send the emails now and make the flow live.

Type: Leak (something broke or wastes money)

## 1. Connect

Give your AI assistant read-only access to Klaviyo and Shopify.

## 2. Ask

```text
List every back-in-stock request in Klaviyo for products that are now in stock in Shopify. How many people are waiting per product, and has anyone been emailed?
```

## 3. Act

Send the back-in-stock emails now and make sure the flow is live.

## Steps

1. Connect Klaviyo and Shopify to Claude read-only, through a connector or MCP server if available, or upload a back-in-stock request export and a Shopify inventory report.
2. Run the prompt so Claude lists waiting shoppers for each product that is now in stock.
3. Confirm in Klaviyo whether each group was emailed. There is no gray area here.
4. Send the back-in-stock emails now, and check the flow is live and triggered by inventory changes.
5. Re-run weekly, and after every restock.

## What it tends to find

210 people waited on a size that had been back for a week. (Illustrative example, not a result from a named store.)

## Watch out

None. Either they were emailed or they weren't.

## FAQ

### Why didn't my back-in-stock flow send?

Common causes are a flow left in draft or turned off, a trigger not linked to inventory updates, or a variant restocked under a new listing. Checking requests against live stock shows which one applies.

### How fast should I email after a restock?

As soon as stock is live. People who asked to be told are among your warmest shoppers, and the item can sell out again before they hear about it.

### Can I use ChatGPT or Grok for this?

Yes. The prompt works with any assistant that can read your Klaviyo requests and Shopify inventory, through a connection or exported files. ChatGPT, Grok and Muse all work this way.

### What if I have more requests than stock?

Email the people who asked first, or send in batches as stock allows. Telling everyone at once can lead to disappointed shoppers or oversold orders if inventory is tight.
