Hi,
Thanks for reaching out. About external accounts…
Several types of external accounts are available, depending on the packages installed on the Adobe Campaign server. The easiest way to exchange data is indeed through the types you mentioned (FTP, SFTP, External database).
You also have CRM connectors that use both external accounts and workflow activities to exchange data. They are described here: https://docs.campaign.adobe.com/doc/AC6.1/en/PTF_CRM_Connector_Configuration.html
A complete list of workflow activities is available here. Some can be used to extract data or files and send them to remote servers (like File Transfer): https://docs.campaign.adobe.com/doc/AC6.1/en/WKF_Repository_of_activities_Introduction.html
Also, there are other possibilities but these are custom and usually require development.
Do you have a use case in mind? If so, don’t hesitate to share it. We’ll surely be able to give you more details.
About “Other” delivery channel…
They can be used to:
1/ define web tracking deliveries
2/ define deliveries for which you want to keep track of the target (in case of an external campaign, i.e. Performed outside of Adobe Campaign)
For example, you could imagine recording all touch points for each recipient for a campaign performed with another tool in SalesForce.com.
Hope this helps.
