What Claude can do with Klaviyo

Klaviyo is built for people who want to segment. Most owners just want to know whether the last send was better or worse than usual, and whether it produced anything. That is a sentence to Claude, not a report build.

Reading your data
  • Campaign and flow performance

    Opens, clicks and click-through rates per send, compared against your own baseline rather than a segment you have to define first.

  • List growth

    How your subscriber list is actually moving, and what a given send did to it.

  • On-site behaviour of email readers

    Read with GA4 so email gets judged on outcomes, not opens.

A real Klaviyo question, start to finish

You talk to Claude. Claude steps out to datanephew when it needs your actual Klaviyo data.

  • How did my last campaign do against my average?
  • Which of my sends gets the most clicks?
  • Is my list growing?
  • Do email visitors stay longer on my site than search visitors?
  • Did that send cost me subscribers?
  • Which month was my best for email this year?

Setup: authorise, paste, ask

Most Klaviyo MCP setups you'll find want you to clone a GitHub repo, install dependencies, manage credentials in a config file, and keep a local server running on your own machine. This one doesn't.

1

Authorise Klaviyo

Paste a read-only Klaviyo API key once.

2

Paste one connector URL into Claude

Add your personal connector URL in Claude's settings. That's the whole install — nothing runs on your machine, and there's nothing to keep alive or update.

3

Ask

Open a conversation and ask about your Klaviyo data the way you'd ask a person. Claude remembers what you looked at last time.

What's free and what's Pro

Your own numbers are free. Anything about data you don't own — competitors, keywords you're not ranking for yet, who links to whom — is Pro.

Klaviyo is free, permanently
  • Everything on this page costs nothing. Klaviyo reads data you already own, so it stays on the free tier.
  • No credit card, no trial clock, no row limits.
  • Pro ($9/mo) adds research into data you don't own — keyword demand, competitor rankings, backlink profiles.
  • Pro also lets Claude act on what it finds: page titles, meta descriptions, tracking tags, sitemap submission.

Klaviyo and Claude — common questions

Is Klaviyo free on datanephew?

Yes, permanently — it reads your own campaign results.

How does Klaviyo connect?

A Klaviyo API key you paste in once. Give it read access only; datanephew never writes to Klaviyo.

Can Claude build a segment or send a flow?

No. The connector is read-only.

Does it read flows as well as campaigns?

It reads your email performance across sends. For anything Klaviyo exposes as a campaign result, Claude can compare it against your own history.
