Most small business owners write marketing emails the same way: stare at the screen, type something, delete it, try again, give up and send something mediocre. The result is newsletters nobody opens and promotions that get ignored. AI can fix this — but only if you know the one thing that separates emails that feel human from ones that read like they came from a corporate press release.
When you ask an AI to "write a marketing email," it gives you something technically correct and completely hollow. It uses phrases like "we are excited to announce" and "don't miss this opportunity." Nobody talks like that. Nobody reads emails that sound like that.
The fix isn't better AI — it's better instructions. Give the AI something real to work with and it produces something real back. Here's how to do it in three steps.
Instead of asking AI to "write a promotional email about your new service," tell it what actually happened: "I just finished a bathroom remodel for a client in Denver. She cried when she saw it. We came in under budget and finished a week early. Write an email to my list that leads with that story and ends with a soft call to book a free quote."
That's it. Give it a real event, a real reaction, a real outcome. The AI can structure and polish — but it can't invent specifics you don't give it. When you provide the real detail, the email reads like it came from a human because it did.
"Write a short email. The story: I helped a restaurant owner cut her Monday prep time by 2 hours using a simple checklist her staff actually follows. She said 'I actually enjoyed my Sunday for the first time in three years.' End with a link to book a 20-minute call with me."
Most people write the subject line first. That's backwards. Write the email body, then ask the AI: "Pull the single most interesting sentence from this email and turn it into a subject line under 8 words."
Subject lines written this way are specific, concrete, and tied to something real in the email — which is exactly what drives open rates. Generic subject lines like "This Month's Update" or "Exciting news from [business name]" get ignored because they promise nothing specific.
Instead of: "November Newsletter" → "She got her Sunday back (here's how)"
AI writes differently than you do. But you can close that gap by building a short voice file: 3-5 sentences that describe how you communicate. Something like: "I'm direct and conversational. I don't use exclamation marks. I write like I'm texting a smart friend, not pitching a boardroom. Short paragraphs. I sometimes start sentences with 'And' or 'But.' I never say 'excited to share.'"
Paste that at the top of every prompt you give AI for email. This takes two minutes to write once and makes every email you generate feel like you.
