The Data Set publication allows you to invite respondents to fill out your form. A data set is just a collection of email addresses and other information, such as the respondents' names, which is used to email out the invitations.
You can use the data set to customize the invitation email, such as addressing the user by name or including other personal information. We call this populating a response. You can also export the invitations to CSV format so that you can send them out in whichever manner you'd like.
You'll need to create a data set first. In order do this, you'll want to go to your Account Manager and find the Data Sets section under your plan. You'll be able to import data sets from Excel and CSV formats, or create a brand new data set through our web-based system.
