Hi Yellow ochre Woodpecker and everyone who voted for cost alerting.

I have a great update on your request. We are currently beta testing new functionality providing email alerts on data usage thresholds.

It is planned to be released on September-October. In case you are curious to be enabled already now to use it, please leave your comment here.

We are able to provide you early access to this functionality and may later contact you to get early feedback about it.
