Answer 1

On your submit button add a js function :

<button type="button" onclick="sendMail()"><?= __('Continue') ?></button>


<script>
    var sendMail = function() {
        /*retrieve all the data you want
        var formData = ...
        */
                jQuery.ajax({
                    type: 'POST',
                    url: '<?= $block->getUrl('*/*/mail') ?>',
                    data: formData,
                    success: function (data) {
                        form.submit();
                    }
                });
        }
</script>

Then in your Mail controller; you can simply send the mail getting all the data you want from the data sent by the request as params.

 //Send mail
 $from = "xxx";
 $dest = "yyy";
 $title = "zzz";
 $mailContent = "azerty";
 $headers = 'From: '.$from. "\n" .
            'To: '.$dest . "\n" .
             'Content-type: text/html; charset=utf-8'."\n".
             'X-Mailer: PHP/' . phpversion();
 mail($dest, $title, $linesContent, $headers);
