I am using Magento 1.9.1. I want to customize my Magento Transactional Emails. To do so, I duplicated
email-non-inline.css from base package into my customized package (into this path: \skin\frontend\mypackage\default\css ).
I made the necessary changes and I uploaded the updated css but the emails arrive with the same design as before, as if the system was unaware of my custom css.
What do I have to do?
