Use the Constituent Registration Info question type to register a new Constituent. This will automatically create a new Constituent record. If the email address matches an existing Constituent record, the information in the existing record can be updated.
When a Constituent registers by submitting a survey, the system does not send the New User or Login Reminder autoresponder - it only sends the Survey Thank You autoresponder if enabled.
Note: You can only add one Constituent Registration Info type question in a survey.
