Built for data-driven teams

Redbird understands both Klaviyo's e-commerce event schema and Mailchimp's audience structure, automatically mapping profiles, custom properties, and engagement data between platforms.

AI that understands email marketing schemas

Redbird natively maps Klaviyo profiles to Mailchimp contacts, translating custom properties to merge fields and events to tags. The platform recognizes suppression lists, segment logic, and consent fields to maintain compliance across both systems. When subscriber statuses, custom attributes, or engagement metrics change in either tool, Redbird intelligently syncs the relevant data without requiring field-level mapping or transformation scripts.
