write a unit file that sends a mail, something like this: 

send-mail-on-failure at .service:
<snip>
[Unit]
Description=Send mail on failure of %I

[Service]
ExecStart=/path/to/my/script.sh %I
</snip>

/path/to/my/script.sh:
<snip>
#!/bin/sh

(
echo "$1 crashed, do something, sir!"
echo "here's the systemctl status output:"
systemctl status "$1"
) | mail lennart -s "OMG! PONIES!"
</snip>

And then add OnFailure=send-mail-on-failure@%P to your units where you
want a mail to be sent
________________________

this seems not to work because after "systemctl --system daemon-reload" the
first error hits /var/log/messages and again the question why not
simplify this with "OnFailure=send-mail" instead writing scripts
and "services" to send a simple mail - this is the exact opposite
of simplify what systemd should do like Lennart always says
