To more easily track survey responses, you can upload a simple CSV file with names in one column and email in the other column with the Add Contacts button.
See the video below to see how you add contacts through a csv for a survey.
Once you upload the csv, you will be able to send surveys directly to the person responsible for filling the survey out and easily keep track of if they have completed it or not on the Survey Share screen. If the contact's survey does not have a full green circle next to iit, then you can quickly send them a reminder to complete the survey through the the mail icon.
