Post id in email body

Hi,

I know I yet asked for some help, but I still have the same problem:

My posts are displayed on the index, and I have a form in a modal for each post.
I’d like the post title to be sent in the mail body.

I’ve tried with the function function my_action_email_msg() given, and also tried to modify it like this:

if ( !in_array($form_id_num, $forms) && $all_forms != true)
 return $ ...

$post_tit = get_the_title();
$post_title = str_replace(" ", "-", $post_tit);
$cust_url = get_site_url();

$page_title = $cust_url. '/' .$post_title;

$email_msg .= '<strong>Link to the post:</strong>' . $inline_or_newline . $page_title . $php_eol . $php_eol;

return $email_msg;

But no way, still hace no result.
Somebody could help please?
Thank
