Two common mistakes that marketers make are: Not adjusting for audience growth/shrinkage (if the same quality audience has grown, you can assume a similar response rate even though your circulation size has changed). Increasing/decreasing the audience of a different quality without accounting for a difference in performance. This is important - by increasing circulation, email list the quality of the audience will decrease and the expected revenue per person for the incremental circulation will be lower.
One way to determine the revenue increase/decrease per person for different quality circulation is based on a loose rule of thumb (divide the % increase by three so that the larger the increase in circulation, the greater the drop-off in revenue per person). Using historical data and trend, you can then forecast your sales curves by order channel.
Most large companies that have multiple order channels typically forecast by fiscal week for both call center staffing and managing the revenue/inventory predictions. Smaller and more internet-based companies may choose to forecast on a monthly basis. Today, more than ever, people are worried about their future and what it holds in-store for them. The economy, unemployment, fears of inflation, the housing industry, the stock market, and more all seem to have no positive outlook for the future. Each day the news stations across every media channel report about doom and gloom in every corner of our world, with one exception - "Network Marketing".
