# An email flow quietly stopped sending

> A Klaviyo flow can stop sending after an edit, a broken filter or an accidental pause, and nothing alerts you. Connect Klaviyo to Claude and ask it to chart weekly sends for every live flow message over 12 weeks. It flags drops to zero, big falls and flows that never sent. Fix the message or filter, then rebuild paused flows.

Type: Leak (something broke or wastes money)
Run it: Weekly

## 1. Connect

Give your AI assistant read-only access to Klaviyo.

## 2. Ask

```text
For every live flow in Klaviyo, show emails sent per week for the last 12 weeks, message by message. Flag any message whose sends dropped to zero or fell by more than half, any live flow that has never sent, and any flow that was paused or replaced. Show the revenue each one made before and after.
```

## 3. Act

Fix the broken message or filter. Rebuild any flow that was paused by accident. This is often a 30-minute fix.

## Steps

1. Connect Klaviyo read-only, through a Claude connector or MCP server if available, or upload flow performance exports.
2. Run the prompt to chart weekly sends per flow message for the last 12 weeks.
3. Compare sends with checkout starts; if traffic fell, sends fall too and nothing is broken.
4. Fix the broken message or filter, and rebuild any flow paused by accident.
5. Ask Claude to re-run the check weekly.

## What it tends to find

The second email in the cart flow stopped sending on 12 Oct. Flow revenue fell 70% in a month. (Illustrative example, not a result from a named store.)

## Watch out

If traffic fell, sends fall too. Compare sends with the number of people who started a checkout.

## FAQ

### Why did my Klaviyo flow stop sending?

Common causes are an edited trigger, a filter that now excludes everyone, a message set to draft, or a flow that was paused or replaced. The sends chart shows exactly when it stopped.

### How do I know it is broken and not just low traffic?

Compare flow sends with the number of people who started a checkout. If checkouts held steady while sends fell, the flow is the problem. If both fell together, look at traffic instead.

### Can ChatGPT or Grok run this check?

Yes. Give any assistant your Klaviyo flow data, through a connection or an exported file, and the same prompt finds the drop. ChatGPT, Grok and Muse all handle this kind of weekly send data well.

### Is it safe to connect Klaviyo to Claude?

Use read-only access. Claude only needs send and revenue numbers. You make any fix inside Klaviyo yourself. Read access is enough to chart sends and spot a drop, so there is no need for edit rights.
