Overview

What Klaviyo is

Klaviyo is a marketing automation platform focused on email and SMS, built primarily for ecommerce brands. It connects directly to online stores and other data sources to unify customer profiles, purchase history, and on-site behavior, then uses that data to target messages precisely. Klaviyo is known for tying campaigns to the revenue they generate.

Data, segmentation, and flows

Klaviyo's strength is data-driven segmentation: brands can target shoppers by purchase history, browsing behavior, predicted lifetime value, and more. Flows are automated sequences triggered by behavior — welcome series, abandoned-cart and browse-abandonment reminders, post-purchase follow-ups, and win-back campaigns. Deep integrations with platforms like Shopify keep customer and order data in sync in real time.

Why ecommerce brands use it

Because Klaviyo attributes revenue to specific messages, brands can see which flows and campaigns actually drive sales, making it a favorite for data-minded ecommerce teams. A full-service agency applies it within email marketing, lead nurture automation, and sales funnels — building segmented flows, safeguarding email deliverability, and connecting it to store data as part of ecommerce development so every send reflects live customer behavior.

FAQ

Klaviyo — common questions

Is Klaviyo worth it?

For ecommerce brands, Klaviyo is often worth it because its deep store integrations, segmentation, and revenue attribution typically drive more email and SMS revenue than generic tools. For simple newsletters or non-ecommerce use, a lighter, cheaper platform may be enough.

Klaviyo vs Mailchimp?

Klaviyo is purpose-built for ecommerce with richer data, segmentation, and revenue tracking, while Mailchimp is a more general, beginner-friendly email tool. Online stores usually get more from Klaviyo; small businesses with basic email needs may prefer Mailchimp's simplicity and lower entry cost.

How much does Klaviyo cost?

Klaviyo has a limited free tier, then prices paid plans by the number of contacts, with SMS billed separately, so cost scales with list size. Because pricing changes, confirm current rates and estimate based on your contact count before committing.
