Definition & Meaning of "email thread"

What is an "email thread"?

An email thread is a series of email messages that are related to the same topic or conversation. When someone replies to an email, the original message and all subsequent replies are grouped together to form a thread. This allows recipients to follow the flow of the conversation easily and see previous messages without having to search for them. Email threads help organize communication and keep all responses and discussions in one place, making it easier to understand the context of the conversation.
