Klaviyo is the autonomous B2C CRM—built to give large brands real-time customer data, AI, and channel execution on one platform, without the developer dependencies and maintenance overhead that slow most marketing teams down.

In the Forrester Wave™: Email Marketing Service Providers, Q1 2026, Klaviyo placed above both Salesforce and SAP, which placed them as Contenders. Klaviyo also received above-average customer satisfaction scores across the portfolio—validated by Forrester, not self-reported.

Yes. Klaviyo is SOC 2 Type II certified and built to support GDPR, CCPA, and the data governance requirements your procurement and security teams will ask about. The platform includes role-based access controls, data residency options, and audit logging.

For brands operating across multiple markets, Klaviyo handles local compliance requirements without requiring separate regional instances. Your IT team can request detailed security documentation through your account team.

Klaviyo powers marketing across email, SMS, mobile push, WhatsApp, web, and paid channels—all from a single customer profile. Every channel runs on the same real-time data, so your team isn't managing different tools to get a consistent view of the customer.

The platform connects to POS, loyalty, and in-store systems through 350+ native integrations, so customer data from every touchpoint feeds the same profile, online and off.

That's exactly what Klaviyo's data platform is built for. Klaviyo connects to your existing stack through 350+ pre-built integrations—commerce platforms, POS, loyalty programs, support tools, data warehouses, and more—and unifies everything into a single, real-time customer profile your marketing team can act on directly.

Klaviyo's Advanced Data Platform brings together data ingestion, identity resolution, and real-time segmentation in one place—no separate CDP required, no reverse-ETL vendor to manage.
