Maybe you can use
wall
that will send a broadcast message to all terminals (shells).

Maybe you have
getent passwd
this works better than finger.

#!/bin/sh
getent passwd |
awk -F: 's[$1]++==0 && s[$3]++==0 {print $1":"$5}'
while read line
do
IFS=":"
set $line
echo "
Hello $2

please log off." |
mail -s logoff $1@mail.usask.ca
done

The awk line eliminates duplicates of fields 1 (ID) and 3 (UID).
