Works like a charm for me (Thunderbird version 147.0) and it helps me out a great deal when sending business emails to sanitized email clients / email platforms that do not recognize padding or margin of individual elements unless it's in a html table. This tool helps me maintain professionally looking spacing on both desktop and mobile in these instances. My standard business email email client does not have an option to change the html source code. It says it has a source code feature, but it still edits the html/css into its own style. Which is annoying and can be clearly seen when checking the html source of the email on the client side. This helps out a great deal!
