Queue only allows us to edit a subject line. This means that recipients get an email with a subject line and an attachment, but no body. In our organization we have to send a pre-email email to let people know it is okay to open the attachment in the forthcoming email.
In addition, extend the length of characters that can be entered into the "Mail To" section. Currently the limit is 255 characters and since we must spell out the full email address for each person receiving the message and our domain name alone takes 25 characters, this limit the number of people I can email to 8 or less.
