Google Forms is very powerful and you can have Google automatically send messages to the user on submission or to you when a new entry has been submitted.

Try this form

This is the script that was used with this particular form: 


function formSubmitNotification(e) {
  var userEmail = e.namedValues["Email"];
  var firstName = e.namedValues["First Name"];
  var lastName = e.namedValues["Last Name"];
  var subject = "Thank you for your feedback";
  var body = "Hello " + firstName + ", /n This email was generated from Google based on your form submission. Create your own Google Form email responders. Visit our blog on";

  MailApp.sendEmail(userEmail, subject, body);
