Hello Everyone is there a way that we can track BCC in Marketing cloud I need this for the tracking of the clients part
There is likely a standard report that includes the value for this setting somewhere, but your best bet is to use SQL Query activities and pull data from the _Job Data View.
There is a field in this Data View labeled 'BccEmail', and it's value is described as
Any email address send in the BCC field
Just first create a Data Extension to hold any data the client would find relevant, and then you can run the query from within automation studio to populate the Data Extension with this information.
