When you send out a survey to our panel, we don't allow the collection of personally identifiable information under any circumstance — it's against our Terms of Use. To learn more, see Collecting Personal Information.
Although you won't be able to personally contact respondents after a survey, you can create successive surveys as follow-ups. We can't guarantee a 100% follow-up rate — it will depend on factors including the time between surveys and the incidence rate of the original survey.
Follow-up surveys require hands-on assistance from aytm. If you're interested, reach out to support@aytm.com or click Chat with us at the top of the page to start a conversation.
