Feature Checklist
Overview
Klaviyo was built from the ground up for e-commerce, and that focus shows in every feature. Unlike general-purpose email platforms that bolt on e-commerce integrations as an afterthought, Klaviyo's entire data model revolves around products, orders, and customer behavior. It integrates deeply with Shopify, BigCommerce, WooCommerce, and other major e-commerce platforms, syncing product catalogs, purchase history, browse behavior, and cart data in real time.
The flow builder is where Klaviyo truly shines. It comes with dozens of pre-built e-commerce flows — abandoned cart, post-purchase follow-up, winback, browse abandonment, price drop alerts, back-in-stock notifications — that can be customized with advanced branching logic based on order value, product category, customer lifetime value, and more. Klaviyo also offers predictive analytics that estimate each customer's next purchase date, lifetime value, and churn risk, allowing you to target campaigns with unusual precision.
Beyond email, Klaviyo includes SMS marketing as a first-class feature, letting you coordinate email and text message campaigns within the same flow. This multi-channel approach is increasingly important for e-commerce brands that need to reach customers across multiple touchpoints.
Who It's For
Klaviyo is built for e-commerce brands, particularly those running on Shopify. If you sell physical or digital products online and want to maximize revenue from your existing customer base through email and SMS, Klaviyo is purpose-built for that use case. It's especially valuable for mid-market and growing e-commerce brands that have outgrown basic email tools and need sophisticated segmentation, automation, and analytics tied directly to their store data.
Our Take
If you're running an e-commerce store, Klaviyo is the strongest email platform available. The depth of its e-commerce integrations is unmatched — the way it syncs product data, purchase history, and browse behavior enables segmentation and automation that simply isn't possible on general-purpose platforms. The pre-built flows alone can generate significant revenue with minimal setup, and the predictive analytics features give you insights that would otherwise require a dedicated data science team.
The downsides are real, though. Pricing scales with your contact list and can become expensive quickly — a store with 50,000 contacts will pay several hundred dollars per month. The platform has a genuine learning curve, and the interface can feel sluggish when you're working with large segments or complex flows. There's also a risk of over-reliance — once your flows and segments are built in Klaviyo, migrating to another platform is painful.
For e-commerce brands that can afford it and are willing to invest the time to learn the platform, Klaviyo delivers exceptional ROI. For non-e-commerce use cases, look elsewhere — Klaviyo's strengths are specifically tied to its e-commerce DNA.
