Klaviyo is one of the most established marketing automation platforms for consumer brands, built around unified customer data that powers email, SMS, and cross-channel campaigns. Its deep integrations, especially with Shopify and other e-commerce systems, let brands trigger highly personalized flows based on real-time behavior and purchase history. AI runs throughout the modern product: predictive analytics (like predicted lifetime value and churn risk), AI-generated segments, AI content and subject-line generation, and newer agentic features such as a Marketing Agent that helps build campaigns and flows and a Customer Agent that resolves support conversations. These are layered on top of the core data and automation engine rather than sold as a separate toy. Klaviyo is a public company (NYSE: KVYO) and prices by active profiles, with a free tier for small lists and paid plans that scale with contact volume; add-ons like AI Composer credits and the Customer Agent are metered separately. Costs can climb quickly as lists grow, which is the main tradeoff. Confirm current pricing, profile definitions, and add-on rates on Klaviyo's site.
