Klaviyo

Connects Claude to Klaviyo's email marketing platform for building and automating campaigns without leaving your editor. You get the full API surface: create and manage email lists, build campaigns, set up automation flows, and handle subscriber data. Generated from Klaviyo's OpenAPI spec by MCP Blacksmith, so it covers the complete set of endpoints with validated request models and built-in auth handling. Useful when you're designing email sequences, segmenting audiences, or debugging campaign logic and want to prototype or test directly through natural language instead of switching between your IDE and Klaviyo's dashboard.
