What you can do with Klaviyo MCP
Email is the highest-margin channel you own, and it only makes sense next to the acquisition that feeds it. Ask both sides in one conversation.

Report on campaigns and flows
Pull campaign and flow performance with the numbers that matter in retention: revenue, recipients, and revenue per recipient, filtered and grouped how you ask.
Query the exact schema
List the report fields Klaviyo supports before querying, so the AI asks for data the API can actually return.

See paid and owned together
Klaviyo lives in the same MCP connection as Meta, Google, and TikTok, so the full e-commerce picture, acquisition filling the list and flows cashing it in, sits in one conversation.
Find the flows that print money
Abandoned cart, welcome, post-purchase: see which flows earn the most per recipient and which have quietly decayed since you last touched them.

Diagnose revenue dips
Separate flow revenue from campaign revenue in one pass, so a scary dip resolves into its real cause, often as simple as fewer sends that week.
Know your list
List profiles and track how acquisition channels grow your audience, because the list is the asset everything else in Klaviyo compounds on.
