You can choose whether replies to emails are grouped in conversations, or if each email shows up in your inbox separately.  


When people reply to an email, Gmail groups responses together in conversations with the newest email on the bottom.

A conversation breaks off into a new conversation if the subject line changes or the conversation gets to more than 100 emails.

  1. Open Gmail.
  2. In the top right, click Settings Settings and then See all settings.
  3. Scroll down to the "Email Threading" section.
  4. Check or uncheck the box for Conversation view.
