How do direct mail response rates relate to a campaign's long-term impact? Provide an example

What will be an ideal response?

Response rates typically understate a campaign's long-term impact. Suppose only 2 percent of the recipients who receive a direct-mail piece advertising Samsonite luggage place an order. A much larger percentage became aware of the product (direct mail has high readership), and some percentage may have formed an intention to buy at a later date (either by mail or at a retail outlet). Some may mention Samsonite luggage to others as a result of the direct-mail piece. To better estimate a promotion's impact, some companies measure the impact of direct marketing on awareness, intention to buy, and word of mouth.
