Klaviyo

What is Klaviyo?

Klaviyo is a marketing automation platform designed specifically for e-commerce businesses, enabling personalized email and SMS marketing powered by customer data. Founded in 2012 by Andrew Bialecki and Ed Hallen, Klaviyo has become the leading marketing platform for online retailers, differentiating itself through deep integration with e-commerce platforms and sophisticated data-driven segmentation. The platform helps businesses move beyond generic mass marketing to deliver precisely targeted messages that drive revenue.

What distinguishes Klaviyo is its native understanding of e-commerce data. Unlike general marketing platforms adapted for retail, Klaviyo was built from the ground up around e-commerce metrics: browse history, purchase behavior, cart abandonment, customer lifetime value, and predicted next purchases. This focus enables automation and personalization that generic tools cannot match. A welcome email can recommend products based on viewed items; an abandoned cart series can adjust messaging based on cart value and customer history.

Klaviyo serves primarily direct-to-consumer brands, from emerging startups to established enterprises. The platform’s free tier for small lists has made it accessible to new businesses, while sophisticated capabilities serve complex enterprise needs. With a strong reputation for deliverability, robust automation tools, and continuously expanding features, Klaviyo has established itself as the default choice for serious e-commerce email marketing.

The deep data integration, powerful segmentation, and sophisticated automation capabilities enable personalized marketing that drives measurable revenue. For serious e-commerce brands, the investment in Klaviyo typically delivers strong ROI through increased customer lifetime value and recovered revenue from automations.

The platform’s complexity is warranted by its power—features like predictive analytics, behavioral segmentation, and dynamic content require sophistication.

The free tier provides genuine opportunity to learn the platform before committing financially, and pricing scales reasonably for growing businesses.

For e-commerce businesses ready to move beyond basic email blasts to data-driven marketing automation, Klaviyo is the obvious choice.
