Hi ronatsai
You can setup Integration between Adobe Analytics and Campaign by setting up an External Account within ACS of type Adobe Analytics, enter the Web Service Credentials (from Analytics) and select the desired Report Suite as below:
This however won't just transfer Analytics data into Campaign.
This would be a two way transfer process, which would feed Campaign Delivery statistics into Analytics and then fetch back remarketing segment data from there to be updated in Campaign.
Kindly confirm which segmentation settings (Campaign Audiences) are you referring to, are these related to some Integration with Audience Manager.
