If you copy and paste your email it will look better and open easier and not expose all your email addresses.
Click on FORWARD OR REPLY, highlight the text and addresses you wish to delete, by putting your cursor at the top left, left click and drag the cursor down thru the addresses or message, then hit the DELETE key on the keyboard.
Once you get to this point you may type in more text.
This way only the text you want sent, will be sent. I do this all the time, it is real easy after you do it a few times.
