System and method for targeted messaging

A system comprising:

• a network interface configured to enable network communications;
• and
• a processor coupled to the network interface, wherein the processor is configured to:
• monitor a text-based communication session among at least three participants;
• detect at least one first contextual information parameter of a first message in a message input field of a client device associated with a first participant of the at least three participants;
• determine if a second participant of the at least three participants is relevant to the first message, based on the at least one first contextual information parameter;
• dynamically update a message recipient list for the first message by removing the second participant from the message recipient list and yielding an updated message recipient list;
• detect in the text-based communication session at least one second contextual information parameter of a second message in the message input field of a client device associated with a participant on the updated message recipient list;
• determine if the second participant of the at least three participants is relevant to the second message, based on the at least one second contextual information parameter;
• and
• dynamically update, in response to determining that the second participant is relevant to the second message, the updated message recipient list for the second message by adding the second participant to the updated message recipient list and yielding a further updated message recipient list.
