Migrating Klaviyo lists to another ESPStandardizing segment exports for reporting

The Klaviyo Normalizer tool is compatible with:KlaviyoShopify Marketing Exports. This tool alone can help you manage and analyze your data effectively. However, a composed workflow using MAILCHIMP NORMALIZER, HUBSPOT NORMALIZER may provide even more powerful data processing capabilities. Consider exploring these related tools for a comprehensive data solution.
Klaviyo exports carry e-commerce-specific fields like SMS and email marketing consent status alongside list or segment membership, laid out with header names that are particular to how Klaviyo structures audiences internally. This tool maps those fields onto a consistent Email/FirstName/LastName/ListName/ConsentStatus/SubscribedDate schema, which is what most other ESPs and CRMs expect on import, and preserves consent-related columns rather than dropping them — those matter for compliance when re-importing a list elsewhere. It's aimed squarely at Shopify and e-commerce teams switching marketing platforms, or anyone standardizing several Klaviyo segment exports into one reporting sheet. As with the other marketing normalizers, everything happens client-side, so subscriber consent and contact data stay off any third-party server during the conversion.

Frequently Asked Questions:

Does it preserve consent status?
