email form from the HTML with JS and PHP

Question

I'm struggling with sending email from the code, and don't understand where can be the problem but I'm not getting any email :( also from the DEV tab of the browser, I'm getting 200 OK which should work, but it's not. I tried different email providers but still no luck.

This is my HTML code:

        <form action="https://example.com/send.php" method="post">
            <input type="hidden" name="form" value="">
            <div class="modal__sub">
                Name of the prod
            </div>
            <div class="modal__title" id="modal-title">
                Some title 
            </div>
            <div class="modal__content">
                <div class="form-group">
                    <label for="">Enter your name</label>
                    <input type="text" name="name">
                </div>
                <div class="form-group">
                    <label for="">Enter your phone</label>
                    <input type="tel" name="phone">
                </div>
                <div class="form-group">
                    <button type="submit" class="btn">
                        <span>Send</span>
                    </button>
                </div>
            </div>
        </form>
    </div>

This is my js script:

 $(document).on("submit", "form", function () {
        var e = $(this),
            t = !1;
        return (
            e.find("input").removeClass("error"),
            e.find("input").parent().removeClass("error"),
            e.find('[name="phone"]').each(function () {
                "" == $(this).val() && ($(this).addClass("error"), $(this).parent().addClass("error"), (t = !0));
            }),
            t ||
                $.ajax({ url: "send.php", type: "POST", dataType: "json", data: e.serialize() })
                    .done(function (e) {
                        $.fancybox.close("all"),
                            $.fancybox.open({ src: "#thanks" }),
                            setTimeout(function () {
                                $.fancybox.close("all");
                            }, 3e3),
                            $("input, textarea").val("");
                    })
                    .always(function () {
                        $("input[type=submit], button[type=submit]").removeAttr("disabled");
                    })
                    .fail(function (e) {
                        console.log(e);
                    }),
            !1
        );
    });

and this is my send.php file:

<?php 

require_once('phpmailer/PHPMailerAutoload.php');
$mail = new PHPMailer;
$mail->CharSet = 'utf-8';

$form = $_POST['name'];
$phone = $_POST['phone'];
                     

$mail->isSMTP();                                
$mail->Host = 'mail.f-line.ge';                                                                                             
$mail->SMTPAuth = true; 
$mail->Username = 'no-reply@example.com'; 
$mail->Password = 'password'; 
$mail->SMTPSecure = 'ssl';                            
$mail->Port = 465; 
$mail->setFrom('no-reply@example.com');
$mail->addAddress('me@example.com');
$mail->isHTML(true);                                
$mail->Subject = 'FILLED FORM';
$mail->Body    = '' .$name . ' ' .$phone;
if(!$mail->send()) {
    echo 'Error';
} else {
    header('location: #thanks');
}
?>
