What is contact history?

Contact history is the historical record of your direct marketing efforts or communications, including detailed information about who was contacted, when, with what message or offer, and on what channel.

Contact history typically includes both targets contacted through campaigns, as well as your hold-out controls who do not receive a communication, but are measured for comparison purposes against the target group.

In Unica Campaign, contact history includes the record of the exact version offer given to each ID, including the values of personalized offer attributes, providing a complete historical view of your marketing communications.

For example, a campaign may produce a list of targeted customers, output through a Call List or Mail List process. That list of customers is written to the contact history table for the example Customer audience level, UA_ContactHistory, in the Unica Campaign system database.

Contact history is recorded and stored in the Unica Campaign system database. There is a separate entry for a base contact history system table for each audience level you create. The base contact history stores the audience membership within each target and control cell used in your marketing campaigns, when all audience entities within the same cell receive exactly the same offer(s). Data from the base contact history table is used in conjunction with the UA_Treatment system table to resolve exactly who received which offers.

Contact history is written to the database for production runs only, not test runs.
