Klaviyo AI

Klaviyo is an email, SMS, and customer data platform built for ecommerce brands on Shopify, BigCommerce, WooCommerce, and Magento. Its AI layer, K:AI, spans marketing, service, and analytics workflows. Klaviyo is publicly traded on NYSE as KVYO, founded in Boston in 2012, and states on its homepage that it powers 205,000+ relationship-driven brands across 100 countries. K:AI includes two autonomous agents: Composer (marketing) and Customer Agent (service). Composer audits flows, segments, and forms, then builds audiences, drafts content, and plans sends from a single prompt. Klaviyo states that Customer Agent resolves 65% of customer questions without a human agent involved, handling product recommendations and order inquiries 24/7. Built-in AI capabilities include predictive analytics (lifetime value, next purchase date, churn risk), AI segmentation via natural language, and Smart Send Time for per-recipient optimization. Klaviyo reports 350+ pre-built integrations. Native integrations are deepest with Shopify, including bidirectional sync covering orders, products, customer profiles, and Shopify Audiences. BigCommerce, WooCommerce, and Magento have dedicated native connectors. Channels include Facebook and Instagram ads for audience sync, WhatsApp for conversational and transactional marketing, RCS for Business, and Social Marketing for organic social. Klaviyo publishes an official MCP server, available to all customers at no additional cost. The remote server at mcp.klaviyo.com authenticates over OAuth and exposes roughly 40 core tools covering campaigns, flows, profiles, segments, templates, and reporting. External AI clients including Claude, ChatGPT, Cursor, and VS Code can read and act on live account data without custom API work. A local server is published as well. The platform is API-first with a REST API covering all major operations. Klaviyo uses an active profiles pricing model, published in USD and labeled as such on the plan builder. The free plan covers up to 250 active profiles, 500 emails per month, $5 of mobile messages per month, and $5 of Composer usage per month, with no credit card required. Driving the plan builder to its floor gives 500 active profiles at $20 per month with 5,000 monthly email sends. At the same floor the Marketing plan, which bundles email with Social Marketing and Customer Hub, is estimated at $78 per month. Composer is a separate paid add-on at $20 per month, which Klaviyo describes as four times the Free plan's usage. Beyond the included usage, Flexible Overage bills $10 per 1,000 credits, or Composer pauses until the next billing period if overage is switched off. Customer Agent is a separate paid add-on listed at $200 per month for 200 AI conversations and currently sold at $140 under a 30% introductory discount, with 50 free conversations included. Klaviyo dates the Customer Agent discount through 30 September 2026, after which that add-on reverts to its list rate. Social Marketing, Reviews, Data + Analytics, and Service are each priced independently, and moving the active-profiles slider changes several of them together. Professional Services and Enterprise are quote-based and require a sales conversation. Predictive analytics, AI segmentation, and Smart Send Time are included in the base plan at no extra cost. Klaviyo suits ecommerce and DTC brands whose marketing runs on purchase data from their store. Teams with non-transactional customer models, such as B2B sales pipelines, should look at HubSpot Sales Hub (from $7/mo billed annually), and brands that want AI copywriting and performance prediction as a separate layer should look at Anyword (from $39/mo billed annually) or Persado. Current state Q3 2026: Klaviyo positions itself as "The Autonomous B2C CRM." Composer (formerly Marketing Agent) remains in BETA and uses credit-based pricing, with recent releases adding campaign briefs, subject line and preview text intelligence drawn from a brand's own historic message performance, and universal content support. Customer Agent detects the language a shopper writes in and, per Klaviyo, supports 113 languages across web chat, email, SMS, and WhatsApp, and now supports custom skills, tools, and agent guidance. Klaviyo's MCP server exposes template creation and update tools, including drag-and-drop templates. Klaviyo's certifications are published as badges on its Conveyor-hosted trust center at trust.klaviyo.com, which names SOC 2 Type II, ISO 27001, ISO 27017, PCI DSS, GDPR and CCPA. Of those, ISO 27017 and PCI DSS sit outside our published certification set. Klaviyo names OpenAI and Anthropic as subprocessors for AI features. Per Klaviyo's published AI FAQs, the third-party generative AI providers behind K:AI are contractually prohibited from retaining customer data or using it to train their own models, and Klaviyo trains its proprietary models only on aggregated or de-identified data.
