One idea for a script. Tested with "ksh" so may need adjustment for "bash".

Code:
address="myaddress@domain.com"
limit=90
df | grep -v "Filesystem" | while read line
do
        case "${line}" in
        "/dev/"*)       device="${line}"
                        ;;
        *)              percent=`echo "${line}"| \
                                awk '{print $4}'|sed -e "s/%//g"`
                        mountpoint=`echo "${line}"| \
                                awk '{print $5}'`
                        message="${device} ${mountpoint} ${percent}%"
                        if [ ${percent} -gt ${limit} ]
                        then
                                echo ""|mailx -s "${message}" "${address}"
                        fi
                        ;;
        esac
done

alert

alert(3alleg4)                                                    Allegro manual                                                    alert(3alleg4)

NAME

       alert - Displays a popup alert box. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int alert(const char *s1, *s2, *s3, const char *b1, *b2, int c1, c2);

DESCRIPTION

       Displays  a  popup  alert  box,  containing  three lines of text (s1-s3), and with either one or two buttons. The text for these buttons is
       passed in `b1' and `b2' (`b2' may be NULL), and the keyboard shortcuts in `c1' and `c2' as ASCII value. Example:

          if (!exists(CONFIG_FILE))
             alert(CONFIG_FILE, "not found.", "Using defaults.",
                   "&Continue", NULL, 'c', 0);

RETURN VALUE

       Returns 1 or 2 depending on which button was clicked. If the alert is dismissed by pressing ESC when ESC is not one of the keyboard  short-
       cuts, it treats it as a click on the second button (this is consistent with the common "Ok", "Cancel" alert).
