Refactor services for better readability

**Feature request**
It would be great to have notifications for utils.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_notifications` with default `false`.

The issue does not name any files, tests, or entry points. Start by locating configuration handling and the utility or service code, then determine where notifications belong and how the enable_notifications default should behave; done means the option is documented, defaults to false, and notification behavior is covered by tests.
