Sync email subscribers with product behavior automatically. Stop manually exporting CSVs, cross-referencing user events, and building segments in two places. Redbird AI connects Mailchimp campaigns with PostHog analytics so your email targeting reflects actual product usage.
Redbird gives your team ready-to-run workflows — just connect your accounts and go.
Automatically create Mailchimp audience segments from PostHog cohorts based on product usage patterns. Users who completed onboarding, abandoned a flow, or hit feature milestones instantly become targetable email audiences. Keep your email lists synced with how people actually use your product.
Add product behavior tags and custom fields to Mailchimp contacts based on PostHog tracking. Flag power users, identify trial users who haven't activated key features, or tag subscribers by their last session date. Turn product analytics into actionable email personalization without manual tagging.
Track email engagement as PostHog events to analyze how campaigns influence product behavior. Connect email opens to feature adoption, measure conversion from newsletter links to in-app actions, and build complete user journey funnels. Stop analyzing email and product data in silos.
Tag email subscribers in Mailchimp when they're included in PostHog feature flag rollouts or A/B tests. Coordinate email messaging with product experiments, send targeted communications to beta users, or notify users when new features go live. Keep your email strategy aligned with feature releases.
Trigger automated email sequences when PostHog identifies users showing disengagement signals like declining session frequency or abandoned workflows. Automatically send retention campaigns, check-in emails, or upgrade offers based on actual product usage patterns rather than time-based triggers.
Combine Mailchimp campaign performance with PostHog conversion funnels to measure true email ROI. See which campaigns drive feature adoption, trial-to-paid conversion, or product engagement. Generate unified reports showing the complete journey from inbox to activation without manual data merging.

Redbird AI understands both Mailchimp's subscriber schema and PostHog's event model, so you can connect email audiences with product behavior without wrestling with APIs or custom code.
Redbird automatically maps Mailchimp contact fields, tags, and segments to PostHog user properties, events, and cohorts. It understands how to match email addresses across systems, translate PostHog event properties into Mailchimp merge fields, and sync audience membership bidirectionally. The AI handles subscriber status changes, respects unsubscribes, and preserves custom field mappings as your schemas evolve. No need to maintain brittle API scripts or worry about duplicate contacts.
