Anonymisation in Surveys – Sending an email that includes a unique participant identifier
When distributing surveys, you can track whether a given participant has responded and if not, send them reminder emails.
You may need participants to log in to ensure that they only complete a questionnaire once, or to enable Snap Online to keep track of the responses. To set up a login page, you must have a known list of participants and they must each have a unique ID that they use to log in. In Snap Online, you must set this up in the participants file.
To make life simple for participants and help to increase your response rate, the email invitations can contain a link to the survey that, when clicked, automatically logs the participant into the survey.
