- basic segmentation
- event tracking
- campaign sender on top of an ESP API
what you lose
- deliverability infrastructure and IP reputation
- years of historical customer data
- mature platform integrations
- compliance across regions
real moats

- proprietary engagement data
- integration ecosystem
Klaviyo
You can easily vibe-code a Shopify webhook receiver and trigger automated emails using Resend or Postmark in a weekend. However, replicating Klaviyo's deliverability optimization, real-time cohort evaluation over billions of events, dynamic visual flow canvas, and enterprise SMS carrier compliance is a massive multi-year engineering lift.
