Response Variance

Your test results indicate a winning response rate. Now, determine what the response rate variance will be based on your test package results, mailing quantity and required confidence level.

The results will likely include a range of responses, detailed below, according to the figures you input.

Total Cost of Ownership

Often focus is put on decreasing the total print and production costs or the cost per thousand price on a document. However, to maximize the cost-effectiveness of any print program you need to look at all contributing aspects of it to determine the total cost of ownership (TCO) so you can make better decisions, reduce overall costs, and improve efficiency and quality.

Calculate the TCO of your program.
