Email organization within Gmail can sometimes involve the automatic bundling of related messages. This feature aims to streamline the inbox by consolidating conversations. For example, responses to an initial email are often grouped together, creating a threaded view of the exchange rather than displaying each message individually in chronological order.
Disabling this automatic grouping can provide users with greater control over how they view and manage their email. It allows for a chronological display of all messages, potentially making it easier to track individual communications within a busy inbox. Historically, email systems presented all messages individually, and some users prefer this linear format.
