Xfinity> Email> " Compose" Is there a way to save a composed Email, before it is sent, for access later?

I use the Xfinity, Email, Compose feature to compose and send E mails. Is there to " save/capture" the complete, composed  Email, including attachments /pictures, at the last step before sending?  The saved Email would be used, for example, to confirm content of what was sent, to whom, date , attachments;  etc.  

Thanks
