Direct-mail questionnaire should not be more than one page because the response rate of mail questionnaire is very less as respondents are having no incentive for taking the questionnaire.

Also most of the times mail questionnaire land up in Spam box of respondent and ignore it. Mail questionnaire questions can be interpreted differently by different individuals and may lead to ambiguity in responses.

Respondents also can’t ask any doubts in mail questionnaire and generally leave the questionnaire partially filled.
