Answer 2

If you want to send a mail to the user filling the form, you need to use server sided language (commonly Php), to retrieve the form data, and send the mail using server side mail functions...

If your purpose is to send to yourself the form data by mail (to avoid server sided handling), you can use the 'mailto' protocole as URL (instead 'http') of the 'action' attribut of the <form> element... but this is limited to opening a prefilled mail in installed user mail application, wich require to be manually send (by user action):
