Overview

- Visual flow builder for automations
- Email + SMS marketing from one platform
- Deep ecommerce integrations (Shopify, WooCommerce, Magento)

Automation
Klaviyo's flow builder is among the most capable in ecommerce email. Standard flows — welcome series, abandoned cart, browse abandonment, post-purchase, win-back — are provided as templates and are easy to customise.
Note
Klaviyo is built around events (e.g. 'Added to Cart', 'Placed Order'), which makes behavioural automation unusually flexible.
Templates
Klaviyo provides a strong library of ecommerce-optimised templates and a drag-and-drop editor with dynamic blocks for products and personalised content.
Segmentation
Segmentation is a core strength: you can build audiences from any combination of behavioural events, purchase history, predictive engagement and custom properties.
Integrations
Native integrations cover Shopify, WooCommerce, Magento, BigCommerce and many apps, plus API access.
Reporting
Klaviyo reports revenue per send, attributed revenue, and flow/campaign performance, connecting email activity directly to sales.
Deliverability
Klaviyo provides SPF, DKIM and custom-domain setup guidance and is generally well-regarded for ecommerce deliverability, with shared-IP default and dedicated options on higher plans.
Ecommerce functionality
Ecommerce is Klaviyo's home turf: deep Shopify/WooCommerce sync, product feeds, dynamic product blocks, abandoned cart and post-purchase flows, and revenue attribution are all first-class.
Ease of use
The interface is modern and well-organised, though the depth of features means there's a learning curve for newcomers. Most ecommerce teams pick it up quickly.
Support
Support is by email/chat with tiers, plus extensive documentation and a large community. Higher plans get faster/priority support.
Pricing structure
Klaviyo's free plan supports up to 250 contacts and 500 email sends. Paid plans are priced per contact count and unlock additional sends, SMS capacity, and features. Pricing changes frequently — always check Klaviyo's pricing page for current figures. It is more expensive than general platforms at scale, justified by ecommerce depth.
Pricing and features can change. Check Klaviyo's website for current information.
