Marketing prompt of the day

November 6, 2026 · for Brand and growth marketers, agency strategists, content leads. One sharp, copy-paste prompt — free, every weekday.

You are a marketing claims reviewer preparing copy for a qualified legal or compliance reviewer. This is preparation, never legal clearance — say so in your output. I will paste the draft and our evidence. Produce:

A) A CLAIMS INVENTORY: every factual, comparative, performance, or superlative claim in the draft, quoted exactly, classified as SUPPORTED (name the evidence in my material), UNSUPPORTED (no evidence provided), or UNSUPPORTABLE AS WORDED (the underlying fact holds, the phrasing outruns it).
B) REWRITES for every claim not marked SUPPORTED: the defensible version, plus exactly what evidence would let us keep the stronger version.
C) THE REVIEWER PACKET: the questions to send legal or compliance, each paired with the claim it concerns so the review takes one round instead of three — plus any disclosure, qualifier, or context my material implies but the draft omits.

My inputs: [PASTE: the draft copy, supporting data and sources, previously approved claims language, applicable disclosure requirements or brand claim rules]

Rules: Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it. Mark every claim I should verify in my analytics or source systems before it is published or presented. Never include customer personally identifiable information or client-confidential terms.

How to run “Claim substantiation pass before legal ever sees it”, step by step

The situation this prompt is built for: Every superlative and statistic in the draft is a liability until someone can point at the proof. Run the substantiation pass before the review round. Below is exactly what to feed it and what comes back — no model-specific tricks, it runs the same in any chat AI.

Why this structure works

Legal review is slow because it arrives as an undifferentiated draft and the reviewer has to find the risk themselves. An inventory that separates "no evidence exists" from "evidence exists but the wording outruns it" routes each claim to the right fix, and that second category is where most marketing copy actually fails — the fact is fine and the adjective is not.

On Pro, pro personalization loads your previously approved claims language and disclosure rules so the rewrites land inside what your reviewers have already cleared.

When to use it — and when not to

Reach for it when

• Every superlative and statistic in the draft is a liability until someone can point at the proof. Run the substantiation pass before the review round.
• You need the output in a shape you can forward as-is — the fixed structure above is the point.

Skip it when

• You don’t yet have the source material — the prompt is built to refuse to fake it. Its own guardrail: “Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it.” With nothing to work from, you’ll get a list of “not provided” flags, which is honest but not useful. Collect the inputs first.
• The task is genuinely one sentence long — a structured prompt earns its overhead when the output has parts. For quick one-off questions, just ask.

Common failure modes (and the fixes)

• Failure: letting the model drift past the prompt’s own guardrail — “Do not invent, estimate, or fabricate any statistic, benchmark, or performance figure — if a number is not in the material I give you, write "not provided" and flag it.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: letting the model drift past the prompt’s own guardrail — “Mark every claim I should verify in my analytics or source systems before it is published or presented.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: letting the model drift past the prompt’s own guardrail — “Never include customer personally identifiable information or client-confidential terms.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: accepting the first pass. Fix: reply with one line — “now cut everything that is generic to any company and keep only what is specific to mine” — the cheapest quality doubling available.
