I've synchronized two objects (from sales cloud) as Contacts in salesforce marketing cloud. These two objects are "Lead" & "Account" and both are mutually exclusive.
I want to update bounce status in sales cloud at Lead & Account level respectively. "_bounce" data view available in marketing cloud only provides subscriberkey (which is contactkey as well in this case) and doesn't tell me if the particular contact belongs to "Lead" object or "Account" object.
When I create journey in journey builder to update bounce status in sales cloud, how do I identify object type (Lead or Account) against contactkey and accordingly update respective object.
