Klaviyo is a B2C CRM and marketing automation platform used by ecommerce brands to turn customer data into personalized email, SMS, and mobile campaigns. Everything is anchored to a unified customer profile, so browsing history, purchase records, and messaging behaviour all feed the same segmentation and reporting engine. Campaigns, automated flows, sign-up forms, and reviews sit alongside analytics dashboards that tie marketing activity directly to revenue.
In recent releases Klaviyo has leaned heavily into agentic AI. Its Composer marketing agent plans calendars, drafts campaigns, audits flows, and surfaces next steps using business context pulled from connected tools. A Customer Agent handles service-side tasks, and an agent builder plus MCP connectors let teams bring Klaviyo data into assistants like Claude or ChatGPT. Integrations cover 400+ apps, with deep support for Shopify, WooCommerce, BigCommerce, Wix, and other commerce stacks.
Pricing starts with a free account that lets you send your first campaign quickly, then scales with contacts and monthly send volume across marketing, service, and analytics tiers. Brands typically pick Klaviyo for its data model and segmentation depth, then expand into the AI agents and service desk as they grow.
Trigger automated email and SMS sequences based on browse and purchase behaviour to recover lost revenue.
Use the Composer agent to plan a campaign calendar and draft messaging per segment in minutes.
Connect ad, POS, and support data into one profile so attribution and retention reporting line up.
Handle helpdesk conversations next to marketing data so customer context is never lost between teams.
