=== Outbound Sync ===
The outbound sync requires an active automation that uses the "Add a Row in Google Sheets" action. As contacts move through this action, their mapped data will sync in real-time to the next available row in your connected spreadsheet.

==== About the "Add a Row in Google Sheets" Automation Action ====
* Only one Google spreadsheet can be used per "Add a Row in Google Sheets" action.
* Only contact fields can be synced, including standard and custom contact fields.
