What is the purpose of using a "20-minute batch" system for emails?

The purpose of using a "20-minute batch" system for emails is to reduce email overload. This approach encourages individuals to check and respond to emails at designated intervals rather than constantly monitoring their inboxes throughout the day. By limiting the frequency of email checks, it helps reduce distractions, allowing for more focused work on tasks without the interruption of incoming emails. This system effectively minimizes the stress and chaos that can arise from a high volume of emails, promoting a more manageable and organized workflow.

The other options do not align with the intent of the batch system. Prolonging inbox monitoring or increasing distractions goes against the fundamental principle of this approach, which is to create a more efficient and less disruptive working environment. Additionally, the system does not aim to limit interactions entirely, but rather to streamline email management to enhance productivity.
