Verify asset versions, file agreements, attach briefs. Every one is ready to run, and you can adjust it in plain language.
Put each submitted draft on its review task with a version note.
Your reviewers find campaign drafts right on their review tasks. A comment shows which version came from email.
Check each review task against the latest ready file.
Your reviewers see whether a task links to the latest file, with the newer link in a comment when the task points to an old draft.
