I'm creating a Journey to drive registration for an event. Contacts should exit the journey either by registering (that's the Goal) or else on the start date of the event -- not some number of days after the previous activity.
Journey Builder won't let me replace the final Wait by Duration activity with a Wait Until Date, which would seem to be the obvious solution. Nor can I have a Wait Until Date followed by a Wait by Duration.
I could potentially set the Wait by Duration based on the send date of the various reminder emails, but this would be clumsy and error-prone since there are numerous emails across different paths.
What's the best way to set something like this up?
