If I delete an Audience Segment in WorkMagic, will it be deleted automatically in Marketing Platform?

No, deleting an Audience Segment in WorkMagic does not automatically remove it from your connected marketing platforms (Meta Ads and Klaviyo).

Instead, the sync will be disconnected, and the segment will no longer be updated.

To fully remove the audience from Meta Ads or Klaviyo, you will need to delete it manually within the respective platform.
