ALERT from work email to another email

Hello,

I am using microsoft outlook 2003. It is also an office computer domain.

Whenever I recieve a WORK EMAIL TO OUTLOOK, I wanted to foward an alert message such as "you got email from work" and then it automaticaly send that alert message to an external email such as  mypersonalemailATgmail.com . I do NOT want to FOWARD any of the content from the work email at all. I just want to be notified when I recieve a work email from my personal email. How do I do that?

Thank you
