Creating Messages – Naming Your Message
Select the folder where you want to store the new document. You will typically collect all the documents for a campaign in a single folder, although this is not a requirement.
Tip: If you inadvertently select the wrong folder, you can change the location of your new document later by clicking 
next to its name and choosing Move from the pop-up menu.
To create a new document in the selected folder, enter a unique name in the text entry box, using only the listed characters.
To overwrite an existing document, select the name of that document from the drop-down list. (Only documents of the same type as the one you're adding are listed.)
