# Reverse ETL

Reverse ETL (or bi-directional sync) sends up-to-the-minute data from the CorralData platform back to your everyday systems like CRMs, marketing automation platforms, and support tools.

**Implementing Reverse ETL can help you and your team manage:**

* Offline Conversions: (e.g., tracking lead-to-revenue impact for ad optimization)
* Custom Audiences (e.g., refining audience targeting for ad platforms)
* Marketing & Operational Automations (e.g., updating CRM fields, generating reports)
* Other Applications (e.g., lead scoring, health scoring, weekly reporting)

**Here’s an example of how Reverse ETL can give you a holistic view of your data:**

A new customer converts from your paid Google ad and books an appointment — but did they actually show up? CorralData’s Reverse ETL connects the dots by sending visit and revenue data back to your CRM, helping sales and marketing know who showed up, how much they spent, and where to invest next.
