Cron sends email if there's any output on either stdout or stderr.  From
the POSIX crontab man page:

       If  standard  output  and standard error are not redirected by commands
       executed from the crontab entry, any generated output or  errors  shall
       be mailed, via an implementation-defined method, to the user.
