New post: Introducing BYO ClickHouse for UserFlux
Comparison

UserFlux vs Klaviyo

Klaviyo is the go-to email and SMS marketing platform for e-commerce — deeply integrated with Shopify and built for lifecycle messaging. UserFlux takes a broader approach: a composable, warehouse-native CDP that combines analytics, automation, personalization, search, and recommendations in a single platform powered by your ClickHouse warehouse as the source of truth.

Key differences between UserFlux and Klaviyo.

Composable CDP vs e-commerce marketing tool

Klaviyo focuses on email and SMS marketing for e-commerce stores. UserFlux gives you the full stack — analytics, CDP, marketing automation, agentic personalization, search, and recommendations — replacing the need for Klaviyo, Segment, Mixpanel, and Algolia in a single platform that works across any industry.

Warehouse-native vs platform-locked data

Klaviyo stores all customer data in its own infrastructure, tied to its email and SMS platform. UserFlux queries your ClickHouse warehouse directly — no data duplication, no vendor lock-in, and full governance over your data.

Customer 360 profiles vs email subscriber profiles

Klaviyo builds profiles around email engagement and purchase history from your store. UserFlux builds full Customer 360 profiles from your warehouse — combining events, traits, and computed properties from every source into a unified view that powers analytics, personalization, and automation.

Usage-based pricing vs contact-based tiers

Klaviyo charges based on the number of active profiles in your account, with costs rising steeply as your list grows. UserFlux uses transparent, usage-based pricing — pay only for what you use, with no contact caps and $150 in free credits to start.

Feature-by-feature comparison.
