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

What do you understand this email offers?
Which phrase needs clarification?
What do you expect after clicking the main link?
What information would you need before acting?
Which part could be shorter without losing meaning?

Author notes / illustrative keys where applicable:
1. The recipient's interpretation reveals whether the offer and its scope are understood. Compare it with the actual terms before improving copy or claiming the message creates purchase intent.
2. An unclear phrase pinpoints where promotional language obscures a condition or benefit. Replace the ambiguity with verified plain wording rather than making the offer sound more attractive through unsupported claims.
3. Expected destination reveals whether the main link's label matches the action it opens. Clarify registration, information or purchase steps without interpreting intended clicks as completed conversions.
4. Missing decision information identifies terms, limitations or context required before acting. Add the verified detail where recipients need it without treating participation in the survey as marketing permission.
5. Removable wording exposes repetition or distraction that competes with the offer's meaning. Shorten the identified passage while preserving important conditions and checking comprehension again with recipients.
