The Contacts tab displays a list of people who have entered their contact details in a flux flow.
In addition to name and email, the list also shows the segment in which the person is located in the Monet. For explanation: The segments are based on usage data of the last 30 days. It is therefore possible that the segments of a contact change more frequently - for example, because they do not come back as often as before.
Finally, you will find the information when this person first interacted with a flow on your site ("First seen").
