You can use the command-line mail command. For example:
30 13 * * * /usr/local/bin/somescript &>/var/log/some.log ; /bin/cat /var/log/some.log | /bin/mail -s "somescript status"
user@domain.com &>/dev/null
The above cron entry will run '/usr/local/bin/somescript', capturing its output in '/var/log/some.log'. On completion of the script, '/var/log/some.log' will be emailed to 'user@domain.com', with the subject 'somescript status'.
