Specific content type and email notification meessage.

I have created a new content type. Suppose: xyz

What I want whenever somebody will create+edited "xyz" content type the subscribed users of that content type(xyz) will get email notification message.

I have tested Trigger module but in Trigger module I cannot set that xyz content type. I can set only the all content type. How can I select specific content type or is there any other solution. Please advise me.
