Northern Trail Outfitters wants emails received from customers to generate cases automatically. How should the administrator ensure that the emails are sent to the correct queue?

An Escalation Rule is used to reassign or notify users for cases that have been open for too long, not for initial assignment upon creation.

A custom email service involves writing Apex code for advanced programmatic email processing, which is an overly complex solution for a standard requirement that Email-to-Case handles declaratively.

Email-to-Case is a native Salesforce feature that automates the creation of cases from incoming emails. It can be configured with routing addresses and rules to automatically assign newly created cases to specific queues or users based on criteria like the email address or subject.

While a Flow could be used to reassign cases after creation, Email-to-Case directly handles the initial creation and assignment to the correct queue more efficiently as part of its core functionality.
