I created a questionnaire that will be sent to our clients. I ran a test and downloaded the response to an excel spreadsheet. Question - it doesnt show who the response came from; how will we be able to know who responded? Is there anyway the email address from the person it was sent be tracked along with the response?
For privacy and security we do not include any identifying information. You can include required fields such as "Name" and "Email" to require users to fill those out so you have a way to identify users. The "Required" attribute is a check box available for each form field in the Properties panel.
