The customer journey is an up-to-date activity feed that reveals how your subscribers are interfacing with you and your marketing efforts. This data is displayed in an easy to follow timeline feed.
By default, the timeline will show any emails they have received and opened, workflows they have started and completed, and any tags that have been applied to the individual (amongst other information). If you are tracking any conversions or events, that info will also show up in the timeline feed.
Viewing the customer journey
Go to the Subscribers tab and select an individual subscriber. Go to the Activity feed to view events and other actions that have been applied to the subscriber. This activity is in chronological order, with the most recent activity at the top.
