see `man 5 crontab`

crontab -e

which will put you in an editor, then you add something like

0 23 * * * /path/to/your/script

Where, the first two fields are min and hour, so in this example, the script would run everyday at 11pm

If you want to capture script output and based on it decide to send email then you may do the following in the calling script:

1- set env variables e.g. PATH, etc.
2- use full path names to folders and files

The calling script that you use in crontab job, can be similar to:

result=`/path/to/myscript`
case $result in
res1|res2)
                 sendmail -s "email for result $result" username@domain.com
                 ;;
res3|res4)
                 sendmail -s "email for dif result $result" username@domain.com
                 ;;
*)
                sendmail -s "no matching result" username@domain.com
                ;;

recent vixie-cron says this:

              field          allowed values
              -----          --------------
              minute         0-59
              hour           0-23
              day of month   1-31
              month          1-12 (or names, see below)
              day of week    0-7 (0 or 7 is Sunday, or use names)
A field may contain an asterisk (*), which always stands for "first-last"


Next field is username in /etc/crontab only
then starts command (i.e no username for other crontabs)

always use crontab command line to edit users' crontab.
