This is a low-effort, high-potential side hustle I accidentally stumbled on… and now I’m sharing it before I turn it into a “masterclass” and charge $997.
Here’s the deal:
You can use ChatGPT to find real leads (like HVAC companies, plumbers, dentists), organize them into a table, and start cold emailing them your offer.
Then, to scale it? You throw in Lindy, the AI assistant that does 80% of the grunt work for you. While you nap, eat, or do literally anything else.
Let’s break it down.
🧰 Step 1: Use ChatGPT to Get Free Leads
🎯 The Prompt:
Just copy/paste this into ChatGPT:
“Give me a list of 10 air conditioning companies based in Berlin. Include their name, website, and email address. Organize the info into a markdown table.”
🔁 Repeat this for:
Other cities (Hamburg, Munich, Stuttgart… go global!)
Other industries (plumbers, gyms, dentists, dog groomers)
💡 Want more leads per run? Just change it to “Give me a list of 20…”
Want niche B2B? “Give me a list of commercial HVAC companies…”
📊 What You’ll Get:
Once you get that sweet table of prospects, you’re officially in business.
📩 Step 2: Write a Killer Cold Email
This is where most people overthink it. Don’t be that guy.
Keep it short, personal, and valuable.
✍️ Copy-Paste Cold Email Script:
Subject: Quick win for your website
Hi [First Name],
I came across your business, [Business Name], while looking for local HVAC pros in Berlin. Your site looks great — but I had a few ideas to help you get even more local leads.
I specialize in helping companies like yours improve visibility with simple SEO and Google Business tweaks. Would you be open to a quick 10-minute call next week?
Best,
[Your Name]
[Your Website or LinkedIn]
💡 Pro Tip: Personalize the first line! Use ChatGPT again:
“Write a friendly intro line for a cold email to ‘KlimaKönig GmbH’ based on their website.”
Now you’re doing high-touch cold outreach… at scale.
🤖 Step 3: Automate It with Lindy (The Fun Part)
Lindy is your virtual assistant that can do the WHOLE process on autopilot. No more copy-pasting like a caveman.
🛠️ Lindy Setup (Step by Step)
-
Sign up at Lindy and get to know it!
(It’s free to start, no stress.) -
Create a new “Assistant”
Call it something fun. Like “Lead Hustler 3000.” -
Give it these instructions:
“Every day at 9 AM, search for 10 HVAC companies in a selected city (e.g. Berlin), gather their name, website, and email, and put the results in a Google Sheet. Then, generate a personalized cold email using the provided script. Send the email via Gmail to each contact.”
