If you have the ability to manage workspaces then you will be able to add emails that will allow those users to be alerted when there is an issue with a data source.
First click on the "Manage" tab.
Then on the bottom right click on "Organizations".
Click on the app that contains the data source that you would like to set up the email that will be alerted if there is an issue.
Now on the top left click on "Edit Org".
On the next view scroll down to where it says "Email recipients" and enter an email on each line of the individual you would like to receive these alerts.
