Why did my Shopify discount code stop working?

The most common reasons are an end date, a usage limit, or an edit to its rules, such as a new minimum order. Shopify does not notify you when this happens.

How do I find codes promised in my emails?

Ask Claude to search your live Klaviyo flows and forms for the code. Any email that still promises a dead code frustrates shoppers at checkout.

Do I need Claude for this?

No. ChatGPT, Grok or Muse can run the same prompt if they can read your Shopify discount orders and Klaviyo content, either connected or from exports.

Is it safe to connect Shopify?

Use read-only access. Claude reads orders and discount settings. You change the code yourself in Shopify. Nothing changes in your store unless you change it. Read access is enough to find a dead code and see why it stopped.

A discount code stopped working

Your best discount code can die on a Tuesday and nobody gets an alert.

A discount code can stop working when it expires, hits a usage limit or gets edited, and Shopify sends no alert. Connect Shopify and Klaviyo to Claude and ask it to chart weekly orders for your top 10 codes over 6 months. It flags sharp drops and why. Re-enable or replace the code and update emails that promise it.

What it tends to findExample

WELCOME10 brought 60 orders a week until 12 Oct. Now it brings 2.

Watch out

Codes tied to one campaign end on purpose. Only flag codes still promised somewhere live.
