What we ship on Klaviyo
Capabilities.
Production-grade Klaviyo work, not theoretical knowledge. Each line below maps to programs we've shipped — across the platform's actual surface area, not the marketing site's.
Implementation
Flow architecture.
Welcome, browse abandonment, cart abandonment, post-purchase, replenishment, win-back, VIP, sunset — built and maintained per-brand.

Klaviyo's CDP layer: events, profiles, segments, predictive fields. Wired to Shopify, Hightouch, Segment, or direct API.
AI
K:AI Marketing Agent + Customer Agent.
Klaviyo's agentic AI from the September 2025 K:BOS launch. We tune the prompts, measure outputs, and pair with Custom Skills.
Predictive
Predictive analytics fields.
Predicted CLV, predicted next-order date, churn risk, expected purchase frequency — wired into segment logic and Flow triggers.
SMS
Postscript / Attentive layered.
SMS as a dedicated channel via Postscript (Shopify-native) or Attentive (multichannel), coordinated with email Flows for cross-channel cadence.
