Depending on the version of SQL Server you could have your DBAs configure an Alert on their server to send them an email. You have to have a mail profile set up on the database server first, then you can go to the SQL Server Agent tree in SQL Management Studio > Alert and create a new alert.

Use the Alert type of SQL Performance Condition or WMI event alert and specify the counter info.

Here's a link to show you how this is done for SQL Server 2008, it is very similiar in 2005: http://msdn.microsoft.com/en-us/library/ms187827.aspx

Great job getting alerts on performance no matter how you do it that's very proactive!
