Migration Steps
Export your data from Klaviyo
15-30 minLog into Klaviyo, navigate to Settings → Export, and download your data in CSV or JSON format. Make sure to include all projects, contacts, and configuration settings.
Prepare your data for import
20-45 minReview the exported data and map fields to Mailchimp's format. Most tools use similar field names, but check for any custom fields that need manual mapping.
Import data into Mailchimp
15-30 minUse Mailchimp's import wizard (usually found in Settings → Import) to upload your prepared data. Run a test import with a small batch first to verify field mapping.
Verify and configure
30-60 minReview imported data for accuracy. Set up integrations, automations, and team permissions. Configure notification preferences and connect any third-party tools.
Cancel Klaviyo subscription
5 minOnce you've verified everything works in Mailchimp, cancel your Klaviyo subscription. Keep your account active for 30 days as a safety net before fully deleting.
