Hey Paul,

Check out OnFailure=

  [Unit]
  Description="HTTP Service"
  OnFailure=mail-root@http.service
  ...

The mail-root@.service is a generic oneshot service that mails you
some stuff.

  [Unit]
  Description="Mailer"

  [Service]
  Type=oneshot
  ExecStart=/path/to/my/mail-script %i

  [Install]
  WantedBy=multi-user.target

And your mail-script is somthing like...

  #!/usr/bin/env sh

  systemctl status "${1}.service" | \
  mail -s "Failed Service: ${1}" admin@xxxxxxxxxxx

See:
