1) You need to create a mail.php file, with the code

<?php
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];

$name = htmlspecialchars($name);
$email = htmlspecialchars($email);
$phone = htmlspecialchars($phone);
$message = htmlspecialchars($message);

$name = urldecode($name);
$email = urldecode($email);
$phone = urldecode($phone);
$message = urldecode($message);

$name = trim($name);
$email = trim($email);
$phone = trim($phone);
$message = trim($message);

if (mail("[email protected]", "Заявка с сайта", "Телефон: ".$phone." Сообщение: ".$message. "ФИО:".$name.". E-mail: ".$email ." . From: [email protected] \r\n"))
 {     echo "сообщение успешно отправлено";
} else {
    echo "при отправке сообщения возникли ошибки";
}?>

Throw this file in the root folder of the site:
/fsi.org.ua/
or
/fsi.org.ua/public_html/
on each hosting differently
2) You have a feedback form on the /startup.html page
- Form https://habrastorage.org/webt/sf/gd/jr/sfgdjr-gw6l ...
- Its code is https://habrastorage.org/webt/8c/td/x5/8ctdx5mxl85...
- In this place, you need to add the POST method - https://habrastorage.org/webt/io/a2/ax /ioa2ax5_io0...

<form action="mail.php" method="POST" class="form contacts-form">

now it is not registered, it is the post method, there is no
After that, everything should work
, nothing else needs to be connected anywhere,
I uploaded this form and this script to my site, everything is sent)
