The results of our first few mailings of the letters you prepared for us proved very successful. We received a 12% initial return, and after accounting for bad addresses on our list, the return rate was really even better. By the time we mailed the third letter in your series, the response was up to 16.6%. This works out to $21 for every $1 of expense or an advertising cost of 4.76%. We're delighted with your work and expect to continue to work with for many years.
