I'm trying to understand how I can do targetted push notifications from Marketing Cloud within a journey.
I'm having a hard time understanding how will I identify specific people and setting their subscriber key in Mobile Studio.
They will have to login using their email address and password in the app, so I will know their email address, but not their EmailStudio subscriber key.
I know that there is the setSubscriberKey command in the SKD, but I wonder if i have to retrieve the subscriberkey from email studio based on the email address and then used that to setSubscriberKey in MobilePush.
I suppose the subsciberkey should be the same in EmailStudio and MobilePush to be able to send emails/push notifications to a person in the same journey.
