Database Mail should be configured on your SQL Server, if it isn’t get it done now there are no excuses, this is one of the main methods that can be used for finding out when there are issues with your SQL Server!

It’s a good idea to setup an operator with a distribution email group email address so if a DBA leaves or moves onto another position the distribution group can be easily updated once in Active Directory as opposed to being updated on every SQL Server.

You could also create additional distribution email groups and add them as operators this is useful if other administrators needs to be aware of certain Agent Jobs failing such as say BI Jobs.
