Reverse ETL

Also called: audience sync, warehouse activation

Reverse ETL moves modelled data out of the warehouse and into operational tools — an email platform, an ads account, a CRM — so teams can act on fields that previously only existed in analytics. It lets the warehouse definition of churn risk or lifetime value be the same one used in campaigns. Watch sync frequency and destination API limits, because a segment of a million rows can take hours to land. Deletions are handled inconsistently across tools.
