Klaviyo is an email and SMS marketing platform that helps e-commerce teams convert customer data into targeted campaigns and automated flows. The tool’s core capability is tying behavioral data (orders, site activity, product views) to individual customer profiles for segmentation and triggered messaging. Klaviyo’s key differentiator is its commerce-first integrations and predictive models—like predicted CLV and churn—built for online retailers and DTC brands. It serves email marketers, CRM managers, and growth teams at SMBs to mid-market merchants. Pricing is tiered by contact count with a free entry level for very small lists and paid plans that scale with usage.
Klaviyo launched as a commerce-focused marketing automation platform and has become a staple in the email and SMS marketing category for online retailers. Founded to help merchants personalize at scale, it positions itself around a single customer view: profiles merge order history, web behavior, and message interactions into an events timeline. That unified data model supports segmented campaigns, lifecycle flows, and analytics aimed at increasing repeat purchase rates and lifetime value. Headquartered in the U.S., Klaviyo emphasizes integrations with storefronts and ad platforms so marketers can act on real-time commerce signals without building middleware.
At the feature level Klaviyo offers multi-step Flows (automations) that support conditional splits, time delays, and API triggers so you can build welcome series, cart abandonment, and replenishment flows. Its segmentation engine enables behavior and property-based segments using on-site events, order attributes, and custom properties for dynamic targeting. Klaviyo natively supports both email and SMS within the same profiles, with sending, compliance, and message templates managed in one workspace. It also includes predictive analytics—predicted lifetime value (CLV), expected next order date, and churn risk—derived from its internal models to prioritize audiences. Reporting shows revenue attribution back to campaigns and flows and includes A/B testing for subject lines and content.
Klaviyo’s pricing is contact-based and scales with the number of active profiles. There is a free tier with fundamental features for very small lists (including email sends and limited SMS credits) to trial flows and profiles. Paid plans start at entry-level monthly pricing that increases with contacts and unlock higher sending volumes, advanced reporting, priority support, and SMS credits as add-ons; enterprise customers negotiate custom agreements for SLAs and data ingestion. Because costs are per-contact, growing merchants should budget for a rising monthly bill as their database and message frequency increase.
Typical users include e-commerce CRM managers using Klaviyo to run automated retention flows and measure revenue per campaign, and growth marketers using predictive CLV segments to prioritize paid ad audiences. For example, an Email Marketing Manager uses flows to recover abandoned carts and improve conversion rates, while a Head of Growth exports Klaviyo segments to Facebook for lookalike targeting. Compared with generalist ESPs, Klaviyo trades a broader feature set for deeper commerce signals and tighter Shopify/BigCommerce integrations, making it a strong choice for retailers focused on lifecycle marketing.
