In an example, a computing system receives an instruction to initiate audio presentation of electronic communications for a recipient. Responsive to the instruction, the computing system audibly outputs each unreviewed electronic communication in a most-recent conversation thread including a most-recent set of unreviewed, reply-linked electronic communications for the recipient. Each unreviewed electronic communication in the most-recent conversation thread may be audibly output in a chronological-sequential order beginning with an oldest unreviewed electronic communication and continuing to a most-recent unreviewed electronic communication. Responsive to completing audible output of the most-recent unreviewed electronic communication from a conversation thread, the computing device audibly outputs each unreviewed electronic communication in a next-most-recent conversation thread including a next-most-recent set of unreviewed, reply-linked electronic communications for the recipient. Each unreviewed electronic communication in the next-most-recent conversation thread may be audibly output in a chronological-sequential order beginning with an oldest unreviewed electronic communication.
