Why is it unnecessary to subcategorize emails?

The rationale for why subcategorizing emails is often deemed unnecessary lies in the advanced capabilities of email clients, particularly their powerful search functionalities. These search engines allow users to locate archived messages quickly and efficiently without the need for complex categorization systems.

When users can simply type keywords, senders' names, or specific subjects into the search bar, they can retrieve relevant information much faster than if they had to navigate through numerous subcategories. This functionality significantly alleviates the need for extensive filing and subcategorization, streamlining communication management and saving time.

In contrast, relying on alternative reasons—like the notion that most emails should be deleted or that categorization can be buggy—does not provide a practical solution for managing emails effectively. Also, while it's true that categorization might help some users stay organized, many find it more productive to leverage modern search capabilities rather than risk losing important communications due to ineffective filing. Thus, the recognition of efficient search tools makes the effort to subcategorize emails largely redundant for many users.
