rETL
Reverse ETL
The reverse of classic ETL: instead of bringing data into the warehouse, you send data from the warehouse back into operational tools (Google Ads, Meta, CRM, email). This is how you activate first-party data — for example syncing high-LTV customer lists to ad platforms.
“rETL” is part of Glossary · Tracking & data — part of the Atlas, Websem's reference of AI search, marketing and data terms.
