**The Data Story (2026 Benchmark Analysis)**

Based on analysis of 500+ e-commerce merchants across Shopify, Magento, and WooCommerce:

### The Hidden Cost: Feature Fragmentation

Klaviyo’s modular pricing creates **feature fragmentation risk**:
1. **SMS underestimation**: Many merchants start with email-only, then discover SMS at scale costs 2-3x email
2. **Push notification surprise**: Klaviyo charges per push notification (not capped)
3. **Advanced forms**: Pop-ups, checkout forms billed separately ($10-50/mo)

Omnisend’s bundled model provides **predictable costs**. You pay for list size, not feature usage.
