I have three workspaces and the alerts sent by the jobs running are not referencing the workspace for example. So if I run the job to dev environemnt I get an alert like if the job has been executed from the prod. This si a huge issue for our admins. ANyways the question here is if we are able to customize the email templates to make them look better or add extra data in them in order to be more informative like the use case I am referring to. 

From the Databricks manual I don't think this is feasible.

My suggestion: We could download the email templates on workspace level, edit them and re-upload them back in order to override the vanilla ones. That would be a nice feature to have and this way the email notifications would look more corporate.
