The wp_mail function sends a lot of emails to me. Code inside. What could be wrong there?

Question

WordPress

my code is in function.php, where if the condition is triggered, then mail is sent with a redirect to the same page, that is, if I have two posts from the form that are not empty, then a letter is sent.

add_action( 'init', 'email_send' );

function email_send()
{
    if (!empty($_POST['send_email']) and !empty($_POST['send_mess'])):
  wp_mail(get_post_meta(95, 'email', true), 'письмо с сайта: ' . $_SERVER['HTTP_HOST'], 'сообщение: ' . $_POST['send_mess'] . "\n" . 'почта отправителя: ' . $_POST['send_email']); //, $headers, $attachments
  $_SESSION['success'] = 'Ваше сообщение отправленно!';
  wp_redirect($_SERVER['REQUEST_SCHEME'] . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] . '#form');
  exit;
 	endif;
}

After sending, a letter arrives, but some incomprehensible letters also come with the necessary letter
