Klaviyo is an autonomous B2C CRM that combines email marketing, SMS, WhatsApp, mobile push and RCS with AI agents and a built-in customer data platform. Composer, its AI marketing agent, analyzes flows, segments and forms from a single prompt and builds an on-brand campaign, while Customer Agent provides round-the-clock support and answers 65 percent of questions on its own. All behavior and transaction data lands in the Klaviyo Data Platform, so every message reacts in real time to what customers actually do. The company supports more than 205,000 brands in 100 countries.
Ecommerce marketers, retention managers, CRM leads and customer support teams at consumer brands are the main audience, from growing online stores to enterprise brands. Support teams get a helpdesk with marketing data at hand, which helps them recommend products and spot upsell chances. Brands that care about compliance can rely on SOC 2 Type II certification and EU and US data storage, and an MCP server lets teams connect Klaviyo to their own AI assistants.
Typical use cases include sending personalized email and SMS flows, such as welcome series, abandoned cart reminders and win-back messages, built from segments updated in real time. A marketer can ask Composer to find the next revenue opportunity and receive a ready campaign, while a service team lets Customer Agent resolve routine questions and escalates the rest. Reviews and social marketing feed more data into profiles, and benchmarks show how performance compares. More than 350 pre-built integrations connect store, helpdesk and analytics systems, and case studies from Dermalogica, Dollar Shave Club and Princess Polly describe revenue growth and lower technology costs.
