If you send a list of messages in sync mode, those messages will be partitioned (randomly by default) and the collated messages will be sent out in batches to each broker. i.e., the original batch may get split into smaller batches - each of those batches is acknowledged. Why not use async mode with required.acks set to 1 (or -1)?
