The #Include# macro allows you to include an external text file in your current email file. If you create a folder in "ArmTracker\Email" called "Extra" and place a text file called "moreinfo.txt", you could include this file in a regular email by specifying:
#Include#Extra\moreinfo.txt#
This macro must be in a line be itself.
Note: The #Include# macro can be used in any email file but will be ignored if placed in the include file you are including.
