I tried to modify files, but it’s not getting effected in New customer order email.
ex paths that I tried to modify are below:
woocommerce\templates\emails\email-addresses.php
woocommerce\templates\order\order-details-customer.php

Kindly please tell me the File Name that I have to modify for changing “Shipping address” to “Delivery address”

No, we want to make few other changes also, like changing the position of billing ph.no, Note etc that is coming in New customer order email.

Kindly please tell me the File Name that I have to modify.
