Follow these steps to view information about the unknown users that Iterable has created for you:
# In this article
# Identify users who satisfied certain criteria
To view a list of unknown user profiles created for a given set of profile creation criteria, navigate to Audience > Unknown User Activation, click the name of the criteria, then choose View in Segmentation from the overflow (three dots) menu.
# Find users who were initially unknown
To determine whether a known user profile was initially created as an unknown
user, review the profile for the presence of the unknownSession event. This
event exists only for users who were initially created as unknown users.
To identify which of these users were merged into a user profile that already
existed in Iterable, look for this event to have a field and value of
isUnknownUser = false.
# View details about a profile creation session
To view details about the session that created an unknown user profile, go to
the user profile, and open the Events page for the unknownSession system
event. For example, in the matchedCriteriaId field, you can see which criteria
caused a profile to be created, where the ID corresponds to a set of criteria in
Audience > Unknown User Activation.
