About
Klaviyo is a comprehensive AI-first B2C CRM and omnichannel marketing platform designed for businesses that want to build lasting customer relationships and drive measurable growth. At its core, the platform is powered by K:AI — Klaviyo's proprietary AI engine — which includes a Marketing Agent (an AI strategist for marketers) and a Customer Agent (an AI-powered support and sales rep for shoppers). The platform supports campaign execution across email, SMS, RCS, WhatsApp, mobile apps, and social channels, giving brands a truly unified omnichannel presence. Klaviyo's Data Platform functions as a real-time customer data platform (CDP) that unifies and activates customer data for precise segmentation and hyper-personalization. Klaviyo Marketing handles automation across all channels, while Klaviyo Service — including a helpdesk and customer hub — helps brands improve support outcomes and turn service interactions into sales opportunities. Advanced analytics surface actionable insights without noise, helping teams understand what's working and where to invest next. With 350+ native integrations spanning advertising, shipping, point-of-sale, loyalty, and subscription tools, Klaviyo plugs seamlessly into any e-commerce tech stack. It also offers free tools like an email subject line generator, ROI calculator, and marketing calendar.
