Unique

: one count per contact. For example, how many ‘unique’ prospects (one count per prospect). There could be more than one inquiry activity logged for a prospective customer but unique only counts the list of named prospects not the list of all the activities for that prospect.

Example: Total Inquiries equals the number of recorded inquiry activities during the month, for instance 22. Representing 22 inquiry activities logged for 10 prospective customers. The Unique Total Inquiries provides a count of the number of unique prospective customers, in this case 10.
