Custom email forward filters

[darrenster]

I'm not sure if this is the right place for this, but I'll ask anyways.

I'm looking for a way to send a email or text message to my cellphone when particular messages arrives in my email box; preferably Gmail account. For example, if I get a long email message from person A, I want to receive a text on my cell "Message from person A" or something along those lines. I know i can setup a forward to forward the entire message, but i don't want to receive a bunch of text messages because the email is so long.

Any ideas to how this could be done?

Thanks
