Frequently Asked Questions
What is Klaviyo?
Klaviyo is the autonomous B2C CRM and AI marketing platform that unifies customer data and automates email, SMS, RCS, WhatsApp, and mobile push to drive personalized, revenue-generating campaigns. Built as both a system of record and system of action, Klaviyo combines a customer data platform, real-time signals, and AI agents to power automated insights and one-click execution.
How much does Klaviyo cost? Is there a free plan?
Yes. Klaviyo offers a free plan with core features, and paid plans scale based on the number of contacts and channel usage (such as email and SMS). Enterprise pricing is also available for large organizations with advanced needs.
What integrations does Klaviyo offer?
Klaviyo offers native integrations with ecommerce platforms like Shopify, plus connectors for payment providers, CRMs, analytics tools, and messaging platforms. We also integrate with your favorite AI tools with our Klaviyo ChatGPT app, Klaviyo Claude Connector, and Klaviyo MCP for building agentic workflows. These integrations sync customer, product, and order data in real time to power personalized marketing and automation.
What channels does Klaviyo support?
Klaviyo unifies email, SMS / Text, RCS, mobile push, WhatsApp and web events into a single customer profile so you can run consistent, data-driven omnichannel marketing.
That unified CDP + real-time signals power cross-channel flows, predictive analytics, and agent decisions to deliver more relevant messages where customers prefer to engage.
How does Klaviyo support enterprise brands?
For enterprise brands, Klaviyo is the unified B2C CRM built to replace fragmented legacy stacks — consolidating data, execution, and analytics into one secure, scalable platform. Unlike rigid suites that require constant developer intervention and data syncing, Klaviyo gives marketing teams the autonomy to launch sophisticated omnichannel campaigns across email, SMS, push, WhatsApp, and web in days, not months.
Built on a flexible data foundation with unified customer profiles, 350+ native integrations, and full developer tooling (APIs, webhooks, SDKs, warehouse syncs), Klaviyo deploys rapidly — with enterprise-grade security, audit-ready compliance, dedicated CSMs, and peak-season uptime backed by SLAs.
