Tips on adding content from existing e-mail and preserving existing formatting:

Using the Windows COPY and then PASTE features from a rich-text Outlook email into an article or page on this website seems to work well. The hyperlinks are usually preserved, though I recommend checking them all before Publishing to make sure the links you have received are current. There is usually some garbage that needs to be cleared out in Source and the spacing often needs to be adjusted.

The best way I have found to check my file and clean up errant code is to save my Article or Page and open it up in a second window to scroll through side-by-side with my edit node.

Caution, Mac users - I haven't had good luck attemping this from Mac Mail. Please comment if you have found a way to work around this using Mac.

Also, best luck creating and editing within Firefox browser (over Safari and Google Chrome).
