How to Expertly Evaluate Your Campaign Results

Traditional methods to determine factored allocation of unknown orders are flawed for several reasons. First, as a general rule, statistical validity of results per segment evaluated requires a minimum response of 100 orders. So if you expect a 1 percent response to a mailing, a list segment size of 10,000 names is required. That’s why test orders of lists generally are 5,000 (2 percent expected response) to 10,000 names (1 percent expected response).
