What is one purpose of canned responses in email?

Canned responses serve as a time-saving feature in email communication, allowing users to prepare pre-written replies for common questions or messages. By using canned responses, individuals can efficiently respond to frequently asked inquiries without needing to compose a new email each time. This enhances productivity and ensures consistency in communication.

While saving custom email signatures is certainly useful, it is not the primary function of canned responses. Instead, the purpose is primarily focused on providing quick access to standard replies. This can streamline workflows, especially for those who receive numerous emails on similar topics, thereby allowing for quicker responses while maintaining a level of personalization.

The other options, such as tracking email opens, auto-deleting old emails, and enhancing email privacy, do not align with the core functionality of canned responses, which revolves around ease of communication rather than managing or securing emails.
