Summary
Klaviyo is the email marketing platform built specifically for ecommerce brands, with deep integrations into Shopify, WooCommerce, and BigCommerce. The free tier supports up to 250 contacts with full access to email features. Predictive analytics use purchase history to forecast customer lifetime value and churn risk. SMS marketing is built into the platform alongside email for unified multi-channel campaigns.
Deliverability
Klaviyo maintains excellent deliverability for ecommerce senders. The platform provides detailed deliverability dashboards showing inbox placement by provider. Automatic list cleaning removes unengaged subscribers to protect sender reputation. Dedicated sending infrastructure keeps marketing and transactional emails on separate paths.
Ease of Use
Klaviyo is powerful but not simple. The interface is data-dense with dashboards, segments, and flow builders that assume familiarity with ecommerce marketing concepts. New users will need time to explore the platform. Once learned, the depth of customer data available for targeting is unmatched.
Pricing
The free tier at 250 contacts is smaller than most competitors. Paid plans start at $20 per month for up to 500 contacts and scale based on list size. At 10,000 contacts, expect to pay around $150 per month. SMS credits are purchased separately. The pricing is justified by the revenue attribution data showing ROI.
Automation
Klaviyo automation flows are built around ecommerce events like browse abandonment, cart abandonment, post-purchase, and win-back sequences. The flow builder is visual with conditional splits based on purchase history, predicted spend, and engagement. Pre-built flow templates let you launch proven sequences in minutes.
Final Verdict
Klaviyo is the clear winner for ecommerce brands that want deep customer data integration and revenue-focused email marketing. The predictive analytics and flow builder are best-in-class for online stores. The pricing can be steep for large lists, but the revenue attribution data helps justify the investment. For any Shopify store serious about email in 2026, Klaviyo should be at the top of the list.
