First, to receive email alerts, you need to makre sure that your email address is confirmed.
For details on budget alers see Budget Emails section in the following help topic https://tmetric.com/help/projects/setting-up-budget/
TMetric doesn't disable a project after it exceeds a budget, because it doesn't know whether the project completed or not.
