It is always nice to have a blank template email so you can always write on a clean slate.  To do this, it is best to edit the template email each time, but do not select the option of saving over that template.  To do this:

1) After writing your content on the TEMPLATE or new email, click on the green box on the bottom

2) Then click on the save link on the top right of the page.  A save option box should open up.

3) Rename your email as something else, do not tick the box marked ’save over current version’ and click save now.
