Try the attached script.  It accepts notmuch queries by message id.
E.g. to get the responses to your OP, you can do:

  $ ./nm-ack id:CAJhTkNhYew6H-bptACTew3gN3DLWg6agTYu8hAkdwFS=z4VFWg at mail.gmail.com
  id:877fr79upd.fsf at maritornes.cs.unb.ca id:20150613205552.GC17381 at chitra.no-ip.org

The first one is David's response, the second one is mine.

Hope this helps,
