Kinetic is the data layer for e-commerce: starting inside the inbox and expanding across the full customer journey. D2C brands use Kinetic to embed interactive product quizzes, preference forms, surveys, NPS, and review requests directly inside their Klaviyo emails, so customers respond without ever leaving their inbox. Forms render natively in Apple Mail, Gmail, and Yahoo, with a beautiful webform fallback for every other client, giving brands 100% recipient coverage. A drag-and-drop builder means marketing teams ship forms without developers, while native Klaviyo sync pushes every answer (including partial responses) straight into subscriber profiles for instant use in segments and flows. Teams deploy Kinetic in welcome journeys, progressive profiling, post-purchase, winback, abandonment, NPS, product finders, and review collection, with the same form infrastructure extending beyond email to cover on-site and other customer touchpoints as brands grow their zero-party data program.
