About contact history
In Campaign, the general term "contact history" refers to information captured about:
*
what offers were sent
*
to which customers (or accounts, or households, depending on audience level)
*
by which channel
*
on what date.
For example, a list of target customers for a campaign can be produced as the output of a contact process (such as Call List or Mail List) in the campaign's flowchart. Each of the target customers belongs to a cell that has been assigned one or more offers. When the Call List or Mail List process is run in production mode (not in test mode) with logging to contact history enabled, details are written to several tables in the Campaign system database.
Together, those tables comprise contact history, which records the specific offer version (including the values of parameterized offer attributes) given to each ID in each cell at flowchart run time, as well as the members of control cells, who are withheld from receiving any communications.
Control cells in Campaign are always hold-out or no-contact controls, therefore customers belonging to control cells cannot be assigned any offers, and are not included in contact process output lists (although they are written to the contact history tables).
