+ Best-in-class e-commerce automation with deep Shopify integration

+ Predictive analytics for customer lifetime value and churn risk

- Free plan capped at only 250 contacts; quickly outgrown

“Klaviyo pays for itself within the first month. Our abandoned cart flow alone recovers 15% of lost sales. It's built for e-commerce in a way nothing else is.”

+ Purpose-built for e-commerce with pre-built automations for cart abandonment, browse abandonment, and post-purchase

+ Email + SMS + push notifications in one platform — no need for separate SMS tools

- Primarily useful for e-commerce — limited value for non-retail businesses

“Omnisend's pre-built cart abandonment and browse abandonment flows were generating revenue within 24 hours of setup. We recovered 15% of abandoned carts in our first month — no other tool made it this easy.”
