Is it possible to limit email syncing based on association labels?

Hey @ADerbyshire

To address the issue of email communication getting jumbled in multiple deals associated with a partner contact, you can follow these steps to prevent emails from logging on associated records:
You can customize which associated records the emails will automatically log to. For example, you can choose to only log emails to the record’s associated tickect records or only to existing contacts in your CRM.

  • Customize the default email associations by unchecking deals or other records you do not want emails to log to.
