We use Lists for the subscriber .We don't have DE enabled.We used to have email address as primary key . Now we decided to have subscriber with same email addresses(family sharing same email).
I cannot unselect the emailaddress as primary key. And i see the subsciber key attribute is filled with email address too.
Can i use subscriber key to store GUID and make it as primary. And remove Email address from being primary key.
I tried to create a subscriber via SOAP api (c#) and assign GUID to subscriber Key in the code . Subscriber gets created but subscriber key = email address not GUID.
3.whats the best solution at this moment?
Do i have to create a new field 'customID' for GUID and make customID plus email address as primary .If i make both as primary then can i have same email address of the subscriber?
can i remove the email address as primary key and make only customID as primary key?
