Mustang List has created an online directory for you to upload and store documents used for your email campaigns. These might be files of email lists you’ve imported, or it might be the text for an email campaign. If you have multiple people working on an email campaign, storing the documents online gives everyone access to the files needed to create the email.

Store documents used for a specific mailing in a directory that relates to the mailing: for example, a directory named "20060801" or  “01aug08” could hold documents used in a mailing sent August 1, 2006. Or you could create a new directory every month that holds files of the email addresses imported that month.
