When you are concerned about immediacy in terms of milliseconds, e-mail is not the way to convey the information. It is not just getting the e-mail to the e-mail server, I assume that someone's e-mail client must pickup the e-mail from the server before it is available to the addressee. That delay could be significant, even for client-server based e-mail clients. For non client-server e-mail clients that poll the server, the delay will be average in minutes. You may want to consider something more direct, like a TCP/IP packet sent directly to the workstation of the addressee.
