How to Use AI to Write Better Emails, Proposals, and Marketing Copy
The blank page is the enemy of every business owner.
You know what you want to say. You just can't figure out how to say it. So you stare at the screen. You type a sentence. You delete it. You try again. An hour goes by and you've got three paragraphs that sound like they were written by a robot pretending to be a human.
Here's the good news. AI solves the blank-page problem completely. And it takes about 30 seconds.
The 3-Sentence Formula
Every time you ask Claude to write something, include three pieces of information:
1. Who it's for. "This email is going to a potential client who owns a bakery."
2. What tone. "Friendly and professional, not salesy."
3. What outcome. "I want them to schedule a call with me this week."
That's it. Three sentences of context, and Claude gives you something you'd be proud to send. Let me show you exactly how this works with five real business scenarios.
Example 1: Cold Outreach Email
Your question to Claude:
Claude will write something warm and specific. Not a generic sales pitch. A real message that sounds like a human wrote it.
The key? That detail about the restaurant being open for 2 years. It shows you did your homework. Specific details make AI output feel personal.
Example 2: Client Proposal
Your question to Claude:
In 30 seconds, you get a structured, professional proposal that would have taken you two or three hours to write from scratch. Review it, add your company details, and send it.
Example 3: Follow-Up After a Meeting
Your question to Claude:
You get a clean, clear follow-up that references the specific things you discussed. Sarah sees you were listening. That's how you win clients.
Example 4: Social Media Post
Your question to Claude:
Quick, engaging, and it sounds like you. Not a corporate press release. A real person sharing real work.
Example 5: Product Description
Your question to Claude:
Instead of spending 30 minutes trying to describe a smell in words, you get something evocative and ready to use in about 10 seconds.
The Golden Rules
AI is a first draft machine, not a finished product machine. Here's how to use it well:
Always review before sending. Read every word. Make sure it sounds like you, not like a textbook.
Add your personal touch. Drop in a detail only you would know. Mention the client's dog's name. Reference something they said in your last conversation. That's what makes it real.
Never send AI output without reading it first. This is your name on the line. AI handles the structure and the blank-page problem. You handle the heart and the accuracy.
Be specific in your questions. "Write an email" gives you generic mush. "Write a 100-word email to a bakery owner about bookkeeping, friendly tone, asking for a 15-minute call" gives you gold.
The Bottom Line
AI doesn't replace your expertise. It handles the blank-page problem so you can focus on the substance.
You still decide what to say. AI just helps you say it faster, cleaner, and without staring at a cursor for an hour.
Try it with your next email. Use the 3-sentence formula. See how it feels. I think you'll be surprised how quickly it becomes the best tool in your business.
