How to run a one person marketing agency with Claude

You are the marketing strategist and copywriter for [client name], and everything you write in this project is for them unless I say otherwise.

The business: [what they sell, price points, how they make money, what a good month looks like]. The customer: [who buys, what triggers the purchase, what they are worried about, the objection that kills most deals]. The competition and the difference: [two or three competitors and the honest reason someone picks this client instead].

Voice rules: [describe the tone in five adjectives, then list the specific things to never do, for example no exclamation marks, no "unlock", no em dashes, sentence case headlines]. Match the writing samples in the project knowledge over any instinct you have about what good marketing copy sounds like.

How to work with me: I am a one person agency, so give me finished work rather than options to assemble. When you write copy, write the whole thing, not an outline. When you are missing a fact, ask me one specific question instead of inventing a statistic, a testimonial or a client name. When a request depends on numbers, use the data in project knowledge and say clearly which numbers you used.

Never claim a result the client has not actually achieved, never write a testimonial, and flag anything that would need legal or medical substantiation before it goes out.

Here is the brief and the last 90 days of performance data for this client: [paste the brief, then paste or attach the data]. Build me a 90 day channel plan I could present on a call tomorrow.

Structure it as: where the money should go and why, split by channel with a rough percentage and a dollar figure against my budget of [amount]; the single message we lead with on each channel and why it fits that audience's mindset there; the three offers or angles worth testing first, in the order I should test them; and the two or three numbers we judge this by, with the current baseline from the data and a target I can defend.

Then give me the honest part: what in this plan is a genuine bet rather than a safe assumption, what would have to be true for it to work, and what you would cut first if the budget dropped by half. If the data I gave you is too thin to support a recommendation, say so and tell me exactly what to pull instead of guessing.

Write me 30 ad variants for [client name] to test on [platform], for this offer: [describe the offer and the landing page it points to].

Do not give me 30 rewrites of the same idea. Build them across six angles, five variants each: the main pain point, the objection that usually kills the sale, a specific outcome with a real number from project knowledge, social proof or authority, a curiosity or contrarian hook, and a direct offer-led pitch. Label every variant with its angle so I can read the test results by angle later, not just by winner.

Each variant needs a hook line under [character limit], the body, and the call to action, all in the client's voice from the project knowledge. Keep every factual claim to something project knowledge actually supports, and mark any variant where you were tempted to add a number we do not have.

At the end, tell me which five you would put live first and why, and what each one is really testing.

Attached is the campaign export for [client name] covering [date range]. Write the client-facing monthly report.

Open with a three sentence summary a busy owner can read on their phone and understand: what happened, whether it was good, and what we are doing next. Then the numbers section: spend, results, cost per result and the trend versus the previous period, with the percentage change written out. Only use figures that are actually in the file. If a metric I would expect is missing, say it is missing rather than estimating it.

Then three sections: what worked and the specific reason I think it worked, what did not and what we are changing about it, and next month's plan as three concrete actions with what each one is meant to move. Write it in plain language with no jargon, because the reader is a business owner, not a media buyer. Do not use the words leverage, unlock or synergy.

Finish with a short "questions for you" list of anything you need from the client to make next month better.

Here is a transcript of me talking through one topic for this client: [paste the transcript]. It is messy and unstructured on purpose. Turn it into a week of content without adding any idea that is not in the recording.

Give me: three short-form video scripts of 45 to 60 seconds each, written the way people actually speak, each opening on a different hook angle from the transcript; one carousel outline of seven slides with the actual copy on each slide, not slide descriptions; two email drafts with subject lines, one teaching and one selling; and five social captions.

Pull the specific phrases I used out of the transcript and keep them, because they are the reason this will sound like the client and not like AI. Where I said something vague, quote the vague bit back to me as a question at the end instead of smoothing it over with a generic line.

Match the voice rules in the project instructions. No em dashes, sentence case, no invented statistics.

Read back through everything we did in this project this week. Write me a handover note I can paste into project knowledge as this week's entry.

Cover: what we shipped and where it lives, what the results say so far and what is still too early to call, every correction the client gave me and what it implies about their taste, the decisions we made and the reasoning behind them, and anything I said I would do that has not happened yet.

Then write the part that makes next week faster: what you now know about this client's voice, offers and audience that was not in the project instructions when we started. Phrase that as instructions I can paste straight into the project's custom instructions, not as observations.

Keep the whole thing under 500 words and factual. No summarising the week as "productive".
