If you provide an identifier other than email, global marketing consent is shown for the last seen email address on the customer profile. List subscriptions are set at the profile level, but you can query them based on any customer identifier.

The ts_status_updated value in the response indicates the last time the subscribed value was changed. If the customer has never been subscribed to a list, the subscribed value is false and the ts_status_updated value is null.

The explicit_opt_in boolean value in the response indicates if the email address explicitly consented to receive marketing messages, or if global marketing consent is null. explicit_opt_in is false when global marketing consent is false or null.
