Sending Emails under conditions!

Dear forumnites and excel experts,

I work at a company that monitors telecom networks and servers. We have daily made excel sheets, in which some cells contain monitoring values. Is it possible to create some kind of template (with formulae or VBA) that when it's filled in daily and these particular cells exceed a value of lets say 900.000, a email (or something similar) is automatically sent to an account? Or any other method of sending a warning to somebody anyhow?

Thanks for your time and help.

Kind regards,
Jeroen
