below function validate the fields if validation is successful so it just shows the message _"All good!"_ but I want to send an email when all is good...

      onSubmit: function(invalid, e) {
        e.preventDefault();
        $('#invalid')
          .show()
          .toggleClass('valid', ! invalid)
          .text(invalid ? (invalid +' invalid fields') : 'All good!');
      }

You need to remove this line - it prevents the page from reloading after the fields have been validated using jquery:

e.preventDefault();
