Add this test after you parsed the fields.

if [ "$email" = "" ] ; then
   echo "no email" >&2
else
   loc=""
fi

Use the dd command to add carriage control information to the file. Write the output of the dd command to a new temp file or you can read from stdout

dd if=inputfile  cbs=75 conv=unblock | 
while read junk email location
do
  # your code here
done
