+ Event-driven automation — trigger messages based on any user behavior, not just email opens

+ Multi-channel messaging (email, push, SMS, in-app, webhooks) from one workflow builder

- $100/mo starting price is steep for early-stage businesses

“Customer.io transformed our onboarding. We trigger emails, push notifications, and in-app messages based on exactly what users do in our product. Our activation rate jumped 35% in the first quarter.”

+ 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.”
