Finding a Shipping method in php

Hi wondering if anyone can help

I am trying to write trying to write some custom PHP for one of my woocomerce email templates. So that is displays a different message according to a ‘Shipping Method’.

1. Can anyone tell me how to call the cutsomers shipping method?
2. Let me know if I am heading in the right direction?

i.e IF shipping method is X then display Y. If shipping method is Z then display V.

<?php

if(‘INSERT SHIPPING METHOD X’) {
echo ‘message Y’;
}

?>
