Hi there @afmarchetti ??
I need for shipping purposes that the list of the products in the email are ordered by sku number.
Thanks for clarifying further! From what I understand, you would like the emails to include the SKU and the products in them to be ordered by SKU.
Since this isn’t a core feature of WooCommerce, this type of customization is not within the scope of our support policy. I am leaving this thread open for a bit to see if anyone can chime in to help you out.
Nevertheless, I found this article that could help with the code you need:

Furthermore, I’d like to recommend looking into my colleague’s response in the thread over here.
Don’t fret, if you do not have a developer or company you can depend on, then we’ve got recommendations for you.
Visit https://woocommerce.com/customizations/ to find the right agency or developer for your specific needs.
I hope that helps!
