You may "copy and paste" content from a previously sent message or from "draft" messages into a new message. In order to keep the "draft" message as a "template", do not send it as a message but sent its content within a new message.
How to recycle a Broadcast Message:
- Open a previously sent message or a "draft" message and "copy" the content
- Select "Create New Message" from the toolbar
- Enter an "Email Subject"
- Paste in the copied content
- Be certain to email the new message and not the draft so that a draft copy will remain as a template
