Summary

Klaviyo's edge is ecommerce-specific data — it pulls in purchase history, browsing behavior, and product catalogs to power genuinely relevant automated flows (abandoned cart, post-purchase, win-back). Pricing scales with contact count, so it can get expensive fast for large lists, and it's overkill for a non-ecommerce newsletter.
