This article explains how to enable or disable conversation view in the standard Yahoo Mail web version and the Yahoo Mail mobile app for iOS and Android.
How to Enable or Disable Group by Conversation in Yahoo Mail
Conversation view is a feature in Yahoo Mail that groups related messages into a single thread. You can turn conversation view on and off in Yahoo Mail settings.
When conversation view is turned on, a single item is displayed for all replies to an original message. For example, if you send an email to a group of people and get dozens of replies, the related messages will remain in a single thread so you can view, move, search, or delete them with just a few clicks.
Conversation view is turned on by default. However, searching through an email thread to find individual unread messages can be a pain. That's why Yahoo Mail has an option to turn off conversation view, so you can see each message as a single item.
