Explore the app marketplaceKlaviyo 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.
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.
Klaviyo offers native integrations with ecommerce platforms such as 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.
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. By combining a unified CDP with real-time signals, Klaviyo powers cross-channel flows, predictive insights, and smarter decisions so you can deliver more relevant messages on the channels your customers prefer.
The Klaviyo platform and Help Centre are localised into 11 languages: English, French, German, Spanish, Mexican Spanish, Italian, Korean, Brazilian Portuguese, Swedish, Polish, and Dutch — with each version continuously being updated as new features become available for market.
To change the language in the Klaviyo platform, go to Settings > Personal and select your preferred language from the Language dropdown. For step-by-step instructions, visit our Help Centre guide.
Klaviyo has implemented measures to meet its GDPR obligations as a data processor, including a Data Processing Agreement, comprehensive security measures, and self-service tools to support data subject rights requests.
Klaviyo also supports lawful international data transfers through mechanisms like the EU–US Data Privacy Framework and Standard Contractual Clauses.
GDPR compliance is a shared responsibility: Klaviyo provides the tools, while each business is responsible for how it collects and uses customer data.
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.
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.
