    Ask Claude Code about Klaviyo

    Ask a question about the accounts your connection can reach. Claude Code can also write the numbers into a file or a script for you. Try "Pull campaign revenue per recipient by weekday and send hour for the last year from Klaviyo and save it to data/klaviyo_send_time.csv." Or ask: "Which flows need a rewrite?" or "Can this run after every campaign?"

Good to know

  • The command uses Claude Code's default local scope. Use --scope user to share the server across projects.

What can Claude Code do with Klaviyo?

Claude Code queries your Klaviyo data while it works in your repo: it saves data as files, checks tracking against code and runs headless with claude -p.

FAQ

Frequently Asked Questions

Not through Lemonado, which only reads Klaviyo. That's deliberate for analysis work: a script can pull campaign and flow numbers on a schedule without any risk of sending to your list.

Yes. Klaviyo's official MCP server is hosted, so Claude Code can use it too. It covers Klaviyo only. Lemonado covers Klaviyo plus your ad platforms, GA4 and the rest of your stack in one connection, so Claude Code can answer questions across them.

Run claude mcp list to see whether lemonado is connected. If it needs authentication, run /mcp inside Claude Code and sign in again. In Lemonado, check that Klaviyo is connected and External tools is on for the company. If revenue is missing, check that your store sends orders to Klaviyo. Klaviyo can only attribute revenue to campaigns and flows when it sees the orders.

Yes, if both are connected in Lemonado. One connection reaches every source you allow, so you can ask things like "Compare Klaviyo attributed revenue with Shopify revenue by week. How much of Shopify revenue does Klaviyo claim?"
