Omnichannel marketing FAQs
What is omnichannel marketing?
Omnichannel marketing is a strategy that connects all customer touchpoints—like email, SMS, and others—into a seamless, real-time journey. It uses a unified customer profile and AI-driven insights to deliver personalized messages across every active channel.
How is omnichannel different from multichannel marketing?
“Multi” means “multiple,” so a multichannel marketing strategy uses more than one channel to reach customers—often independently. “Omni” means “all,” and in omnichannel marketing, the focus is on integrating all active channels to create a seamless and coordinated customer experience across them.
Which marketing channels does Klaviyo Omnichannel support?
Klaviyo supports omnichannel marketing across:
- Email messaging
- Text messaging (SMS, MMS, RCS)

All channels are connected through a single B2C CRM for consistent messaging and improved results.
