Key differences
| Category | Omnisend | Klaviyo | Why? |
|---|---|---|---|
| Channels & Omnichannel | Omnisend natively combines email, SMS, and browser push in one automation builder, whereas Klaviyo combines email, SMS, WhatsApp, mobile push, reviews, and more (with web push via app/web integrations), so each is stronger depending on whether your priority is web push or broader app/WhatsApp messaging. | ||
| Ease of Use | Vendor messaging and third‑party reviews describe Omnisend as more intuitive and approachable for small teams, while Klaviyo’s richer feature set tends to come with a steeper learning curve despite a polished UI. | ||
| Feature Depth & Analytics | Klaviyo offers a fuller customer data platform with advanced analytics and predictive metrics (e.g., predicted CLV, churn risk, next order date) that can drive segments and flows, while Omnisend’s reporting and CLV views are strong but less sophisticated. | ||
| Pricing | Omnisend’s paid plans start a bit lower than Klaviyo’s and generally remain more affordable at comparable list sizes, especially once you factor in SMS and web push usage. | ||
| Scalability & Integrations | Klaviyo integrates with 350–400+ apps, underpins an AI‑first B2C CRM used by more than 170k brands, and is often preferred for complex, large‑scale ecommerce stacks, whereas Omnisend is tightly optimized around mainstream ecommerce platforms like Shopify, WooCommerce, and BigCommerce. |
