After switching to unthreaded view, you’ll notice several changes in your Inbox. First, the number of messages in your Inbox will likely increase (1). This is because, rather than showing a single entry for the entire conversation, Gmail now intersperses messages throughout your Inbox, based on the date they were received (2).
Switching to unthreaded view (and switching back)
- Open your Gmail Settings
- On the General tab, under Conversation View, select Conversation view off.
- Click Save Changes.
To switch back to Conversation view later, just come back here and select Conversation view on.
