#!/usr/bin/env zsh -f
# Purpose: This script will email all PDFs from one folder to a designated recipient
#
# Note: this script uses 'emate' which is a part of MailMate.app (https://freron.com)
#       and assumes that the app is already properly configured to send email.

	# change this to the email address you want to send the files to 
MAIL_TO='[email protected]'

  # this is the folder where the PDFs will be sent from 
SOURCE_DIR="$HOME/Desktop/Send"

  # this is the folder where the PDFs will be moved to after they are sent 
MOVE_TO="$HOME/Desktop/Sent"


## you should not _have_ to edit anything below this line.
