In an embodiment of the present invention, a first message is determined. The first message is associated with two or more users. The two or more users include a sender of the first message and one or more recipients of the first message. In response to determining that a first user of the two or more users is currently generating a second message, which is a response to the first message, it is determined whether a second user of the two or more users of the first message is currently generating a third message, which is a response to the first message. In response to determining that the second user is currently generating the third message, the first user is notified that the second user is currently generating the third message, and the second user is notified that the first user is currently generating the second message.
