You can You the above script to have customized mail.
This script is expecting 5 parameters:
"#!/usr/bin/sh
# $Header: backup_exit_notify.sh,v 1.3 2003/08/13 14:05:11 $
#bcpyrght

#
# backup_exit_notify.sh
#
# This script is called by the NetBackup scheduler, after an individual
# client backup has completed (including media closure and image db validation.
#
# NOTE: this script will always be run in "background" mode, meaning that
# the NetBackup scheduler will NOT wait for it's completion.
#
# This script:
# receives 5 parameters:
# CLIENT - the client hostname
# POLICY - the policy label
# SCHEDULE - the schedule label
# SCHEDULE_TYPE - the type of schedule: FULL INCR UBAK UARC
# STATUS - the backup status for this job
# STREAM - the backup stream number for this job
# must be executable by the root user
# should exit with 0 upon successful completion"
So You can try to do a if statement, ie.
if [ "$5" -gt 1 ]
then ....
