Currently, there is no validation of data entered as a survey response. If a form asks for a phone number, the user can enter anything such as a letter or a dash. The following validation would be extremely helpful: 

• Email (Besides validating the format, it would be a plus if the email addresses themselves were validated for authenticity)
• Integer (Including option to set Min and Max)
• Numeric (Including option to set Min and Max)
• Phone
• Zip

Thanks!
