Retention.com focuses on helping Shopify merchants recover lost shoppers and enhance Klaviyo flow revenue through its identity resolution software. It integrates well with various marketing platforms but is particularly tailored for Shopify.

Aimerce emphasizes ease of use with a fully automatic, no-code setup, making it accessible for users who may not have technical expertise. It also offers identity resolution and customer data integration but lacks specific mentions of Shopify-centric features.
