How does Klaviyo integration work?

Tailor Size Guide pushes events to Klaviyo: Size Chart Opened, Size Recommender Used, Custom Measurements Submitted. Pushes profile properties: preferred size, last fit feedback, body measurements (with consent). Use these to build segments and personalize.

Useful Klaviyo flows?

(1) Browse abandonment with their saved size pre-filled. (2) Welcome series with size-finder CTA for first-time buyers. (3) Post-purchase fit survey 30d after delivery. (4) Win-back targeting customers who returned for size — recommend better-fitting alternatives.
