AI prompts for small business marketing

Copyable ChatGPT and Claude prompts for small business owners: social posts, customer emails, review replies, product descriptions, and simple plans.

By Learn2Prompt · Updated October 25, 2026 · 5 min read

If you run a small business, marketing is probably one of a dozen jobs you do, often late at night after the real work is done. AI tools can take a lot of the blank-page pain out of it: drafting social posts, writing customer emails, replying to reviews, and turning a jumble of ideas into a simple plan.

The catch is that generic prompts produce generic marketing, the kind that sounds like every other business. The prompts below are built to pull out what's specific about your business, which is what customers actually respond to.

First: write a short "business brief" you can reuse

Instead of explaining your business from scratch every time, write a short description once and paste it at the start of any marketing prompt. Keep it in a note on your phone.

Copy-ready prompt

Your reusable business brief

About my business: I run [type of business] in [town or area]. My customers are mostly [who they are]. What makes us different is [one or two honest things, e.g. family-owned for 20 years, same-day repairs]. Our tone is [e.g. friendly and down-to-earth, never pushy]. Things to avoid: [e.g. discount-heavy language, slang, emojis].
Fill in the [blanks], then paste into Claude or ChatGPT (free account). Leave out account numbers and addresses.

Pasting this brief before each request below makes the results consistently more on-brand.

Social media posts

Copy-ready prompt

A week of social posts

[Paste your business brief.] Write 5 social media posts for this week about [topic, product, season, or event]. Each post should open with a line that stops someone scrolling, include one genuinely useful tip or detail, and end with a simple question or call to action. Keep each under 60 words. Use no more than 2 hashtags each. Vary the style so they don't all sound alike.
Fill in the [blanks], then paste into Claude or ChatGPT (free account). Leave out account numbers and addresses.

Weaker prompt

Write a post for my bakery.

Stronger prompt

Write a post for my neighborhood bakery about our new pumpkin bread. Mention it's made with a family recipe and only available on weekends this month. Warm and cozy tone, under 50 words, end by asking followers about their favorite fall treat.
Why it worksThe first produces something interchangeable. The second includes real details (family recipe, weekends only), a clear tone, and an engagement hook.

Replying to reviews

Review replies are public, so they're marketing too. People reading your reviews often care as much about how you respond as about the review itself.

Copy-ready prompt

Reply to a negative review

[Paste your business brief.] Write a public reply to this review: "[paste review]". Thank them, acknowledge the specific problem without being defensive or making excuses, briefly mention what we're doing about it, and invite them to contact us directly at [contact method] to make it right. Under 80 words. Sound like a real owner, not a corporate statement.
Fill in the [blanks], then paste into Claude or ChatGPT (free account). Leave out account numbers and addresses.

Copy-ready prompt

Reply to a positive review

Write a short, genuine reply to this positive review: "[paste review]". Mention one specific thing they said so it doesn't feel copy-pasted. Under 40 words. Warm, not over the top.
Fill in the [blanks], then paste into Claude or ChatGPT (free account). Leave out account numbers and addresses.

Always read the reply before posting, and never include customer details beyond what they shared publicly.

Customer emails and newsletters

Copy-ready prompt

A customer email that people actually open

[Paste your business brief.] Write a short email to our customers announcing [news, e.g. new opening hours, a seasonal menu, a workshop]. Give me 3 subject line options under 50 characters. Keep the email under 150 words, put the key information in the first two sentences, and end with one clear action ([what you want them to do]).
Fill in the [blanks], then paste into Claude or ChatGPT (free account). Leave out account numbers and addresses.

Product or service descriptions

Copy-ready prompt

Product description from real details

Write a product description for [product or service]. Here are the real details: [materials, size, what it does, who it's for, price if relevant]. Lead with the benefit to the customer, then the key details in 3 short bullet points. Under 100 words. Don't add claims I haven't listed (like "best in town" or health benefits).
Fill in the [blanks], then paste into Claude or ChatGPT (free account). Leave out account numbers and addresses.

That last instruction protects you. AI tools sometimes add flattering claims that sound good but that you can't back up, and some kinds of claims can create real problems for a business. Only publish what's true.

A simple monthly marketing plan

If marketing feels scattered, ask the AI to help you organize it into something manageable.

Copy-ready prompt

A realistic one-month plan

Act as a practical marketing adviser for very small businesses. [Paste your business brief.] I have about [number] hours a week and a budget of [amount] for marketing. Make a simple 4-week plan with no more than 3 activities per week, using the channels I already have: [e.g. Instagram, an email list of 300 customers, a Google Business Profile]. For each activity, say what to do and roughly how long it takes.
Fill in the [blanks], then paste into Claude or ChatGPT (free account). Leave out account numbers and addresses.

The constraints (hours, budget, existing channels) keep the plan realistic. Without them, AI plans tend to assume a full marketing team.

Make the AI sound like you

If drafts still feel generic, paste two or three posts or emails you've written yourself and ask the AI to match their style. This is one of the strongest ways to keep your voice; see our guide on giving AI examples.

Frequently asked questions

Can AI replace a marketing agency for a small business?

For many small businesses, AI can handle a lot of day-to-day drafting: posts, emails, and descriptions. It doesn't replace knowing your customers, and you still need to review everything. Larger campaigns may still benefit from professional help.

How do I stop AI marketing from sounding generic?

Give it specific details about your business, a clear tone, and examples of your own writing. The reusable business brief in this guide is the quickest way to do that.

Is it okay to use AI to reply to customer reviews?

It can help you draft calm, thoughtful replies, especially to negative reviews. Read and personalize every reply before posting, and keep private customer information out of the prompt.

Which AI tool is best for small business marketing?

Both ChatGPT and Claude handle these writing tasks well. Try the same prompt in each and use whichever produces drafts closer to your voice.
