If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which category was unclear?
What frequency did you expect?
What explanation would help choose?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: readers cannot distinguish product updates from marketing offers.
2. Expected frequency reveals whether preference labels distinguish occasional, scheduled and event-triggered messages. Explain the actual available settings and their limits; a stated expectation does not establish that a system already supports that choice.
3. Turn the requested improvement into a testable next step. One illustrative action is: describe categories and actual frequency expectations.
