Klaviyo

This connects Claude to Klaviyo's email and SMS marketing platform, handling customer profiles, event tracking, campaign flows, and segmentation. You'd reach for this when building e-commerce integrations that need to sync customer data, track behavioral events like cart abandonment or product views, or trigger automated marketing flows based on user actions. The skill covers both server-side API calls with private keys and client-side tracking, plus all the standard e-commerce events Klaviyo expects like "Placed Order" and "Started Checkout." It's marked medium effort, which feels right since Klaviyo's API is well-documented but you'll need to think through event schemas and profile property structures for your specific use case.
