Hi Kapil,
If you need to send data from AAM to any other Salesforce platform (apart from their DMP), then we do not have server to server integrations.
We can set up a daily export on your s3 or ftp for the customer IDs/ device IDs and their corresponding segment IDs. You can get that batch file and check if that can be imported to their email marketing platform. (Please contact AAM customer care for this request)
Apart from that, you can create URL destination if they can receive real time data via http.
Thanks,
Varun Kalra
