[RESOLVED] form to email formatting

[etoast]

Hello
I have a form that outputs to email.

foreach($_POST as $key => $value) {
$message = $message . "$key: $value\n";
}

At the moment the email has about 100 lines of data, one after the other. What I want to do is put extra blank lines in certain places to break it up a bit. For example, the $key for the 6th line is "Nationality" - after which I would like a line break. And in several other places.

What is the best way to go about this please?
Many thanks

I figured it out if anyone happens to be looking for the answer too:

foreach($_POST as $key => $value) {
if($key == "Address1"){ $key = "\n".$key.""; } 
$message = $message . "$key: $value\n";
} 

where "Address1" is the input field immediately below "Nationality"
