How to show HOSTNAME in service notifications?

I have Nagios setup and e-mail notifications are being sent successfully, however, currently notifications don't tell me which host is having problems.
I have multiple servers running, and would like to have notifications tell me specifically which server is down/having trouble.
So basically, how do I add the HOSTNAME to notification content?
Any advice would be greatly appreciated, thanks!

You will need to modify your notify-service-by-email command (or whichever command you have set) to include the $HOSTADDRESS$ macro.

Thanks so much for the quick reply.
Could you confirm where I set the variables, such as: $HOSTADDRESS$. Or are they globally set by nagios and stay the same for everyone?

That is a macro, and is set by Nagios on a per-object basis. So if you have a host with the address of 192.168.1.100 and a service is attached to it, both the host and the service will have access to that value in the macro. This can be used in notification commands, event handlers, etc.
