includes emailSubject, emailToAddress, or emailMessage the compose sheet is pre-filled with
the values.

JSON Data
------------------------

Most folks use the control panel to configure the JSON data for this plugin but it's useful to
see what it may look like. This is the simplest example.

{
     "itemId":"343434",
     "itemType":"BT_sendEmail",
     "emailSubject":"You gotta check out this app!",
     "emailMessage":"Be sure to download it and check it out."
}
