Email message based on Shipping Method

I read someone else’s question about this on your support forum, and you guys recommended:

“There isn’t any native way to do this, if you are code savvy then you can using the hooks in this plugin. Each text output is run through hooks and filters so you can override from a function file. For example, the body text can be filtered on “kadence_woomail_order_body_text” ”

But I am not sure how to make this work – are you able to give me any other information? I have a basic understanding of how this works, but I really need a bit more guidance if you can help.

I figured if anybody would know, it would be you! Please let me know if your plugin has this capability or if you know of a good snippet to try.
