Klaviyo vs Mailchimp: which is better for eCommerce?

Shopify integration depth

Klaviyo's Shopify integration syncs: orders, products, customers, browse events, cart events, and predictive data. You can segment by product category purchased, number of orders, average order value, predicted next purchase date, and churn risk.

Mailchimp's Shopify integration syncs orders and customers. You can trigger abandoned cart emails and product recommendations. Browse abandonment and predictive segmentation are not available.

Pre-built flows

Klaviyo ships with production-ready flows for: welcome series, abandoned cart, browse abandonment, post-purchase, win-back, and sunset. Each is customisable and well-designed for DTC stores.

Mailchimp has pre-built automation templates for abandoned cart, welcome series, and product recommendations, but the triggers and conditions are less sophisticated.

The verdict

For a Shopify store that sends more than a basic newsletter: Klaviyo is the better tool, even though it costs more at scale. The depth of eCommerce data it can access makes its campaigns more targeted and its revenue attribution more reliable.

For a very small store or a business that just wants a basic email list alongside its Shopify store: Mailchimp is sufficient and cheaper at small contact counts.
