The readability of direct-mail copy

Abstract
We report the results of a well-controlled experiment which tested the readability of direct-mail sales letters. Surprisingly, the mailings of a subscription offer for technical newsletters, sent to both professional and layperson segments, produced no significant differences in response rates as a function of readability levels. This study suggests that readability formulas, as tools for tailoring messages for different segments, may not have broad applicability in the field.
