We are using Salesforce contact id as subscriber key within Marketing cloud.
For one of the Journeys, we have duplicate contacts in our subscriber list (contacts with same subscriberkey and same email) where we are using combined primary key (Sno(Unique) + SubscriberKey) for Operational/Transactional Comms. Upon activating the journey, it's deduplicating by email address which is not our requirement as the subscribers must receive multiples transactional emails.
I tried using Guided Send, it works absolutely fine.
Is there any way where we can avoid deduplication by email address in Journey Builder?
