Sending surveys via email tends to be significantly more cost effective than conducting surveys via regular mail. Email survey software automatically adds a link to an email and directs repondents to the survey hosted on the internet. When the respondent clicks on that link, they are directed to a survey hosted at QuestionPro.com. All of the survey responses are sent to a centrally located server that you can access via your administrative account. The data is completely secure and only available to you as the survey administrator. If you have an email list, you can easily conduct a survey via email using Email Survey Software.
