Database Mail Messaging Objects
Applies to: 
SQL Server
Azure SQL Managed Instance
The msdb database is the Database Mail host database. This database contains the stored procedures and messaging objects for Database Mail. Microsoft SQL Server Management Studio includes the Database Mail Configuration Wizard for enabling Database Mail, creating and managing profiles and accounts, and configuring Database Mail options.
Objects in msdb database
Service Broker must be enabled in the msdb database. However, Database Mail does not use Service Broker networking. Therefore, users do not have to create a Service Broker endpoint to use Database Mail. The external Database Mail process uses a standard ADO.NET connection to communicate with SQL Server.
Database Mail exposes the following objects in the msdb database when Database Mail is enabled.
These objects are the interface for Database Mail within the mail host database. Other objects are installed to implement the functionality provided by the objects listed above. However, those objects are reserved for internal use.
