I need assistance with two things:
1-how can I send the survey to a large amount of people (approx. 120) via email and
2-is there a way that they can only vote through the link 1 time and not repeatedly be able to access it and use the link multiple times
Both concerns will be addressed by using a SurveyGizmo Email Campaign:
An email campaign allows you to send your survey to a large contact list that you upload via a spreadsheet.
Each contact that you add to the campaign is provided with their own unique link. Each unique link allows only one responses before it is closed, so a person could not vote multiple times.
Hope this helps!
