title: Using AppleScript to set a mail message to Plain Text
body: <p>I have an AppleScript that nicely collates information and creates an email message with attachments.</p>
  
  <p>I cannot find a way for the script to set the message format to "Plain Text" which is required by the receiving inbox (rather than the default "Rich Text").</p>
  
  <p>Is there an AppleScript way (or trick) to setting the message format to "Plain Text"?</p>
