I am using Apple Mail on Lion.
I need to preview a .eml file in Litmus, but I can't import it. If I forward the message it changes the html. I tried opening in TextEdit and copy/pasting the HTML, but it is all encoded weird.
In Apple Mail, if you click "Forward" it will re-render the email. However: if you click "Send Again" it should retain most of the original formatting.
- Open Apple Mail, and open the .eml file
- Click the Message menu, and then Send Again
- Create a new email test in Litmus
- Open the test in Litmus, and download the HTML content (lower right-hand side)
I've tested this with good results.
