# Sign-up popup stopped working

> When email sign-ups fall sharply while site traffic holds steady, the popup usually broke or its offer changed. Connect Klaviyo, Google Analytics and Shopify to Claude, ask it to chart daily sign-ups against sessions for 90 days, and check the form, its offer and welcome-code orders. Restore the popup and test it yourself.

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

## 1. Connect

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

## 2. Ask

```text
Chart email sign-ups per day for the last 90 days next to site sessions per day. Flag any day sign-ups fell by more than 40% while sessions held steady. Then check: is the popup form still live, did its offer change, and are welcome-code orders in Shopify falling at the same time?
```

## 3. Act

Restore the popup or its offer. Sign up yourself with a test address to check the code arrives and applies at checkout.

## Steps

1. Connect Klaviyo, Google Analytics and Shopify read-only, through a Claude connector or MCP server if available, or upload sign-up, session and order exports.
2. Run the prompt to chart daily sign-ups next to sessions and flag sudden drops.
3. Ask whether someone changed the popup on purpose; then the finding is the cost of that choice.
4. Restore the popup or its offer, then sign up with a test address to confirm the code arrives and works.
5. Re-run the check weekly.

## What it tends to find

The popup switched from 10% off to a giveaway on 3 Oct. Sign-ups fell 55% and welcome-code orders fell with them. (Illustrative example, not a result from a named store.)

## Watch out

If someone changed the popup on purpose, the finding is 'here is what that choice costs', not 'it broke'.

## FAQ

### Why did my email sign-ups suddenly drop?

If traffic stayed the same, the popup likely stopped showing, broke on some devices, or its offer changed. A weaker offer can cut sign-ups even when the form works.

### How do I test my sign-up popup?

Sign up yourself with a test email address. Check that the welcome email arrives and that the code applies at checkout. Try it on a phone and a desktop, since a popup can break on one and not the other.

### Can other assistants run this prompt?

Yes. Any assistant that can read the same sign-up, session and order data, connected or from an uploaded file, can follow it. That includes ChatGPT, Grok and Muse.

### What if we changed the popup on purpose?

Then nothing is broken. The useful output is what the change cost in sign-ups and welcome-code orders, so you can decide whether to keep it.
