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 serves DTC brands and ecommerce merchants from SMB through enterprise tiers. 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. Customer Agent resolves 65% of customer questions autonomously according to Klaviyo, 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 400+ 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, so 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. Notable gaps: Salesforce CRM and HubSpot CRM sync require third-party middleware, and Klaviyo lacks native connectors to B2B or enterprise sales stacks. Klaviyo uses an active profiles pricing model. The free plan covers up to 250 active profiles, 500 emails per month, 150 mobile message credits, and 10,000 Composer credits, with no credit card required. Paid email plans start at $20/month for 251 to 500 active profiles with 5,000 monthly sends, then $30/month for 501 to 1,000 profiles, and $45/month for 1,001 to 1,500 profiles. Composer is a separate paid add-on at $110/month for 16,000 monthly credits, a 30% introductory discount from $157/month. Customer Agent is a separate paid add-on at $140/month for 200 AI conversions per month, also a 30% introductory discount, down from $200/month. Social Marketing, Reviews, Data + Analytics, and Service are each priced independently. 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 is designed around ecommerce purchase data. Its predictive AI does not translate to B2B SaaS, professional services, or content businesses where transaction order signals are absent. HubSpot Sales Hub (from $7/mo billed annually) or ActiveCampaign are better suited for non-transactional customer models. At scale, Klaviyo's active-profile pricing climbs faster than Mailchimp or Brevo, making it a deliberate platform investment rather than a low-cost email tool. Brands prioritizing AI copywriting depth and performance prediction should evaluate Anyword (from $49/mo) or Persado (custom pricing). As of Q3 2026, Klaviyo positions itself as "The Autonomous B2C CRM." Composer (formerly Marketing Agent) is 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 replies across 100+ languages on 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 holds a 4.6 rating on G2 from 1,356 reviews, carries SOC 2 Type II and ISO 27001 certifications with ISO 27017 and PCI DSS also confirmed on its trust center, and runs annual third-party audits. 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.
