  I'd just run this from cron now and then:

    #!/bin/sh
    export PATH=/bin:/sbin:/usr/bin

    host=$(hostname)
    admin='you@preferred.mail'
    zpool status -x | mailx -s "Zpool status for $host" $admin
    exit 0

  If you can do without constant "EVERYTHING'S FINE!" messages:

    #!/bin/sh
    export PATH=/bin:/sbin:/usr/bin

    host=$(hostname)
    admin='you@preferred.mail'
    pat='all pools are healthy'

    if zpool status -x | grep "$pat" > /dev/null; then
        logger -t 'zpool' "$pat"
    else
        zpool status -x | mailx -s "Zpool status for $host" $admin
    fi
    exit 0
