What is an Email Thread?

Organizing email into threads helps you keep track of a conversation.

Definition: An email thread is an email message and a running list of all of the subsequent replies pertaining to the original email. The messages are most commonly organized in chronological order, and participants may refer to or re-post snippets from earlier parts of the commentary for clarification. It is customary for all participants to keep the discussion on topic, and considered poor email etiquette to deviate from the original topic.

Smartphones and email applications can automatically group email messages into threaded views, which groups all of the replies to the original message together and makes it easier to find all of the messages pertinent to the thread.
