Our Take
Real-time integration with store data powers predictive send-time and purchase-likelihood features that generic email platforms can't replicate. Pricing scales with the contact list, which is the main constraint to model as a list grows past the free tier's 250 profiles. The platform is a poor fit if your business isn't selling products directly online. B2B teams and service businesses will find it shaped around assumptions that don't match their data model.
