Do not begin final output while facts are still moving. Confirm campaign identity, individual offer headline, value and qualifying condition, expiry and exclusions and redemption code or instruction and record the approved revision. Offer value, code, qualifying spend, eligible locations, expiry and exclusions need approval as one record.. Run spelling, design and accessibility reviews, then save the editable .mpub before creating a PDF. A later correction needs a new proof; editing after approval without repeating review breaks the audit trail.
