Associating electronic messages related to the sharing of a file

A computer-implemented method, comprising:

• identifying that feedback was provided that is associated with a file shared by one or more computers of a sharing service;
• causing one or more second computers of a messaging service to transmit, over a network, a first electronic message to a first recipient, wherein the first electronic message relates to sharing of the file;
• causing the one or more second computers of a messaging service to transmit over the network, a message identifier associated with the first electronic message to the one or more computers of the sharing service;
• accessing, from the one or more computers of the sharing service, message metadata, the message metadata including a message identifier for a first electronic message relating to a sharing of the file;
• generating using the message data, via the one or more computers of the sharing service, a second electronic message that is part of a same message thread as the first electronic message;
• and
• causing the one or more second computers of the messaging service to transmit the second electronic message to one or more recipients.

A system, comprising:

• a sharing service, comprising one or more computers including one or more processors operative to perform actions to:
• identify that feedback was provided for a file shared by the sharing service;
• cause one or more second computers of a messaging service to transmit, over a network, a first electronic message to one or more recipients, wherein the first electronic message relates to sharing of the file;
• cause one or more second computers of a messaging service to transmit, over the network, a message identifier associated with the first electronic message to the one or more computers of the sharing service;
• access message metadata associated with the file from the sharing service, the message metadata including a message identifier associated with the first electronic message sent by a sender to the one or more recipients relating to the sharing of the file by the sharing service;
• create a second electronic message that is associated with the first electronic message using the message metadata;
• identify one or more recipients of the second electronic message based, at least in part, on one or more of the sender of the first electronic message or the one or more recipients of the first electronic message;
• and
• transmit the second electronic message to the one or more recipients.
