In addition to Level 1, response rates and other key performance indicators that
have been identified as applicable to the campaign (e.g. return on investment and/or
evidence of behavioural changes) shall be measured in accordance with documented
procedures.
Campaign response rates and contact history shall be recorded for customers and,
provided permissions have been gained from the data owner or supplier, for prospects
as well. Where the intention is to contact the same customers and prospects for
future campaigns, the campaign response rates and contact history shall be used
to determine the frequency with which to send DM communications to the customer
or prospect in order to achieve optimum results in future campaigns.
NOTE The Data Protection Act 1998 requires that data processed for any purpose
shall not be kept for longer than is necessary for that purpose for which is was
intended.
Two or more targeting analysis techniques shall be conducted and evaluated to maximize
the targeting results.
