Klaviyo wins for ecommerce (Shopify, BigCommerce, WooCommerce); Mailchimp wins for general SMB email marketing, content creators, and service businesses. The gap has widened in 2027 for ecommerce use cases.
Mailchimp (owned by Intuit) remains the most-used email platform in 2027. Intuit Assist (Mailchimp's AI brand) handles content generation, subject line testing, send-time optimization, segmentation suggestions, and customer journey recommendations with full QuickBooks data integration.
Klaviyo is the default for ecommerce brands, generating $3.8B in attributed revenue for its customers in 2027 per its public reports. Klaviyo AI includes predictive CLV, churn risk scoring, product recommendation engines, SMS+ flow optimization, and benchmark-driven forecasts.
