Klaviyo

Klaviyo is a cloud-based B2C CRM and marketing automation platform. It combines customer profiles, behavioral data, campaign execution, analytics and service tools in one system.

The platform supports email, SMS, RCS, WhatsApp, mobile push, web forms and reviews. Its primary users include ecommerce and other consumer-facing businesses that need behavior-based communications.

Klaviyo was founded in 2012 by Andrew Bialecki and Ed Hallen. The company lists Boston, Massachusetts, as its global headquarters.

Klaviyo supports visual campaign and flow builders for automated email, SMS and push communications. Flows can respond to events such as sign-ups, purchases, browsing activity and abandoned checkouts.

Customer profiles combine transactional, behavioral and engagement data. Marketers can use segments, predictive analytics, product recommendations, send-time optimization and revenue attribution to personalize campaigns.

Additional capabilities include web forms, mobile messaging, reviews, customer service tools, analytics dashboards and AI features. Klaviyo also provides Composer and Customer Agent products for assisted campaign creation and customer interactions.

Klaviyo offers a free plan with up to 250 active profiles, 500 email sends per month, $5 of mobile messaging usage per month and $5 of Composer usage per month. The free tier also includes basic reporting and email support for the first 60 days.

Paid pricing varies according to active profiles, email volume, mobile messaging usage and selected products. Klaviyo lists separate pricing for Marketing, Reviews, Marketing Analytics, Customer Hub, Helpdesk, Composer and its data platform. Enterprise plans are available through sales.

Klaviyo does not use a single flat price for all paid accounts. Buyers should use the official pricing calculator for a current quote based on contacts and channels.
