Once you have a public facing one page web site newsletter, select all on the page, then copy. Using keyboard short cuts, you can click on the page, then control-a (for select all), then control-c (to copy). Do this on a browser while browsing the public facing web site newsletter.

n crm, create a new email template. In the body of the email, we can not right click and select paste. However, we can use the control-v, keyboard shortcut to paste.
