Frequently asked questions
What is Klaviyo?
Klaviyo is the autonomous B2C CRM and AI marketing platform that unifies customer data and automates email, RCS, WhatsApp, and mobile push to drive personalised, 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 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 organisations with advanced needs.
What integrations does Klaviyo offer?
Klaviyo offers native integrations with e-commerce platforms like Shopify, plus connectors for payment providers, CRMs, analytics tools, and messaging platforms. We also integrate with your favourite 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 personalised marketing and automation.
Which channels does Klaviyo support?
Klaviyo unifies email, SMS*, 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.
Does Klaviyo support WhatsApp messaging natively?
Yes. Klaviyo provides native WhatsApp messaging built directly into the platform, with no third-party integration required.
WhatsApp is available in Klaviyo for both marketing campaigns and two-way conversational messaging, so brands can send targeted promotions, automate messages, and manage customer conversations in one place. All WhatsApp activity is powered by the same real-time data, segmentation, and automation used across email and SMS.
Because WhatsApp is fully integrated into Klaviyo, businesses can deliver consistent, personalised experiences across channels while maintaining a complete, unified view of each customer.
