1. A computer-implemented method for managing message communications, comprising: receiving, by a computing device, a first message, wherein the first message is addressed to or received by multiple recipients, wherein the first message includes an email, a chat, SMS, or other message communication formats; registering, by the computing device, a user action to reply to the first message; creating and displaying in a user interface, by the computing device, a message composition or editing interface in response to the user action; distinguishing at least two operation modes of replying to a multi-recipient message, wherein the two operation modes comprises a first operation mode and a second operation mode, wherein the first operation mode comprises a reply only to the sender of the multi-recipient message, and the second operation mode comprises a reply to multiple recipients of the multi-recipient message; detecting, by the computing device, whether the user is replying only to the sender of the first message as in the first operation mode, or to multiple recipients of the first message as in the second operation mode; and displaying, by the computing device, a notification, wherein the notification indicates whether the user is replying in the first operation mode or in the second operation mode.
