When you send out a survey to our panel we don't allow the collection of personal identifiable information under any circumstance as it is against our terms of service (TOS) policy. So you will be unable to personally contact our respondents after the survey.
An alternative would be to create multiple surveys that you send out over a period of time, however we can't guarantee a 100% follow up rate for each subsequent survey. Follow-up surveys require hands-on assistance from AYTM, so if this path interests you feel free to reach out and we will be happy to help!
If you have any additional questions click the chat bubble or email firstname.lastname@example.org. We look forward to hearing from you!
