How do I remove duplicates in Journey Builder before sending an email? All our data extensions (source data extensions, too) have the ID as the subscriber key so there are duplicate email addresses in all the data extensions. Automation Studio has this feature already but I need it in Journey Builder since we resend to the people who haven't opened the email.

    Hey, you can do this with the journey builder settings using journey is no re-entry, but this only works if your contactID (your primary key) is the subscriber key.
