Use Claude for marketing after the audience, offer and evidence are settled. It can help shape and adapt copy, but it cannot decide that a customer result, comparison or deadline is true. Put approved facts in a campaign packet and keep unsupported language visible.
Prepare the source packet
Suppose a fictional scheduling app is launching a calendar export. The approved packet says:
- exports confirmed appointments as CSV;
- works from the web dashboard;
- available to existing customers on the Standard plan;
- no measured time-savings claim;
- launch date still needs approval.
Write a claim ledger before drafting:
| Proposed claim | Source status | Allowed wording |
|---|---|---|
| Export appointments | Supported | “Export confirmed appointments as CSV” |
| Saves hours | Unsupported | Remove |
| Available today | Not approved | Do not publish a date |
| Works automatically | Unsupported | Explain the manual export action |
Draft one message, then adapt it
Use only the approved campaign packet and claim ledger.
Draft a 120-word customer email announcing CSV export from the web dashboard.
Audience: existing Standard customers.
Do not claim time savings, automation or a launch date.
After the draft, list every factual claim and its supporting source line.
Put missing information under Review before publishing.After the email passes review, adapt the same approved message to a short in-app notice. Do not ask for five channels at once; each format has different space, context and approval needs.
Compare two channel outputs
The email draft can say: “The CSV export for confirmed appointments is planned for the web dashboard. It is intended for existing Standard customers. [Release owner: confirm availability date and wording before sending.]” The placeholder remains in the review copy, not in a customer message. Hold publication until the release owner supplies an approved date and availability statement.
The in-app notice has less room. Its review copy might read: “CSV export for confirmed appointments in the web dashboard. Standard customers. [Hold for launch approval.]” Do not ship the placeholder; release approval determines whether the present-tense claim is true. Neither version may claim automatic delivery or saved hours. The action changes by channel; the evidence does not.
| Review point | Customer email | In-app notice |
|---|---|---|
| Audience | Existing Standard customers | Signed-in eligible customers |
| Action | Open dashboard and export | Open export control |
| Product fact | Confirmed appointments to CSV | Same fact |
| Launch timing | Hold until approved | Hold until approved |
If the in-app notice appears to all plans, the audience targeting is a product defect, not a copy problem. Ask the channel owner to verify the targeting rule before publication.
Fix the first bad draft
If the result says “Save hours with automatic exports available now,” mark three failures: savings lack evidence, the export is not described as automatic, and the date is unapproved. Correct the ledger first, then ask for a revision that removes those claims. A style change alone will not repair them.
Run a claim-to-source review
Underline every factual statement in the final copy, including eligibility and the action verb. Beside each one, put the source line and the approver. The reviewer rejects claims that are merely plausible: “one-click,” “secure,” “faster” and “available today” all need their own evidence and scope. A qualifier must travel with its claim; “for existing Standard customers” cannot disappear when the copy becomes a social post.
Keep legal or policy review where your organization requires it. Claude can draft options from a bounded packet, but it cannot approve advertising claims on the company’s behalf.
Choose Claude when the review fits
Claude is useful when the source packet is substantial, the output needs several revisions or several related drafts must preserve the same facts. A short one-line notice may need no AI tool. For repeatable brand context, use a maintained Claude Project rather than pasting an uncontrolled archive into every chat.
Questions about Claude for marketing
Can Claude create the campaign strategy too?
It can organize options from supplied research, but the target, budget, offer, risk and measurement decision still need accountable owners.
Should I upload our entire brand library?
Start with the smallest approved set: current voice rules, offer facts and a few relevant examples. Old or conflicting material makes review harder.
How do I prevent invented statistics?
List allowed numbers and require a source line after each quantitative claim. Remove any number that cannot be traced to the packet.
Can the same draft be used on every channel?
No. Preserve the message and evidence, then adapt length, context and action for each channel and review the new version.
Use the AI campaign brief to establish the source packet before drafting.
