Put the choices on one page
Make one simple proof that includes the requested spelling, layout direction, artwork version, and date. A customer can then respond to a single readable reference instead of reconstructing the request from a message thread. The proof is a review aid, not approval by itself.
Archive the answer with the version
When a reply arrives, keep it with the exact proof that was reviewed. That record helps a small shop separate confirmed wording from an open question on the next order. Browse /updates/ for more small-shop workflow ideas.
