This method is used to gather information from a wide audience without requiring face-to-face interaction or internet access.
Synonyms: postal survey, mail questionnaire, paper survey, postal questionnaire

Mail surveys allow researchers to reach participants who may not have internet access or prefer traditional communication methods. They are useful for collecting data from diverse populations and can provide thoughtful, well-considered responses since participants complete the survey at their convenience.
Researchers design a questionnaire and mail it along with a cover letter explaining the study and instructions for completion. Respondents fill out the survey and return it by mail. Follow-up reminders may be sent to increase response rates. This method is often used in academic research, market research, and public health studies.
