This ChatGPT + Gemini Email Funnel Made $100K With Zero Ads

ChatGPT and Gemini were the only tools I used to write an email funnel that made $100K – without spending a dollar on traffic.

I didn’t plan on building an email funnel. I just had a Notion product that wasn’t selling the way it could. But then I asked ChatGPT (GPT-4 Turbo) and Gemini (Google DeepMind) to help me write 5 emails with a strategy behind them.

That funnel became my most profitable asset.

Zero ads. No promo budget. Just a warm-up sequence, a strong offer, and AI that helped me speak clearly.

This is the full breakdown of how it worked – and how you can build the same funnel this weekend.

ChatGPT helped me map the strategy – from first opt-in to final conversion email.

ChatGPT didn’t just write emails. It gave me a funnel strategy in minutes.

I started with:

“Act as a DTC email strategist. I’m selling a Notion product to freelancers. Help me design a 5-email funnel that builds trust and converts without hard selling.”

GPT-4 laid it out like this:

Welcome Email: Why I built the product (no pitch)
Problem Email: Pain points of disorganized freelance work
Solution Email: Breakdown of what the template does
Social Proof Email: Screenshots + testimonials
Launch Email: Scarcity window or bonus

Then I asked:

“Write version A (casual tone) and version B (direct tone) for each email.”

I mixed and matched. Built the final funnel in 2 hours. Uploaded it to ConvertKit. The open rate on Email 1? 78%.

Gemini helped me refine every sentence – based on actual buyer behavior and audience data.

Gemini was my CRO expert. After pasting in my entire funnel, I prompted:

“Scan these emails and flag weak subject lines, unclear CTAs, and unnecessary repetition. Compare tone and pacing with top-performing email sequences in the productivity space.”

Gemini flagged three CTAs that buried the value proposition. It suggested this instead:

“Click to see exactly how this dashboard organizes every client and deadline in one view – no extra tools.”

It also shortened my third email by 40% without losing meaning. Gemini highlighted the scroll-drop zone based on where most email readers quit.

Then it gave me A/B test subject lines:

“The template that ended my Sunday scaries”
“What my clients saw that made them pay faster”

I used both. Email 2 hit a 53% open rate. Email 4? 7.2% click-through.

ChatGPT and Gemini worked together to build my email capture page – fast and clean.

ChatGPT helped me write the headline, Gemini helped me optimize the rest.

I asked GPT-4:

“Write 5 versions of an email opt-in page for a Notion template. Include a hook, 1-liner benefit, and ‘what you’ll get’ bullets.”

Then I gave Gemini the full landing page and said:

“Audit this page for clarity, hierarchy, and trust signals. Suggest one image change and one structural improvement.”

Gemini told me to move the testimonial above the fold, add a progress bar to the opt-in form, and rephrase the subtitle like this:

“Join 1,000+ freelancers using this to plan smarter and bill faster – without adding another app.”

The opt-in rate went from 11.6% to 24.2% after those tweaks.

Chatronix let me run ChatGPT and Gemini together – and compare their ideas without losing my flow.

Working between ChatGPT and Gemini can get messy fast – unless you use Chatronix.

Chatronix let me:

Run both models side-by-side on the same prompt
Save and tag email copy by goal: hook, proof, CTA
Track A/B versions, iterations, and final outputs
Create reusable prompt stacks like “email optimizer” or “list-builder assistant”

It became my full AI workspace. Without it, I’d still be copying and pasting between tabs.

What made this funnel hit $100K: empathy, rhythm, and proof

The funnel didn’t work because it was clever – it worked because it was true.

Here’s what mattered:

The Welcome Email felt like a journal entry, not a pitch
The Problem Email told my story – not just pain points
The Solution Email showed the product in use
The Proof Email included 3 buyer replies with screenshots
The Final Email gave a reason to buy today

Gemini helped make it sharp. ChatGPT helped make it mine.

By Day 28, the funnel had converted 1,946 buyers. Total revenue: $101,320. Zero ads. Zero cold DMs.

✅ Use ChatGPT to sketch the structure and tone
✅ Use Gemini to refine clarity, CTAs, and subject lines
✅ Use Chatronix to organize everything, compare models, and scale
✅ Don’t try to sound like a marketer – just tell the truth clearly

AI can’t make you trustworthy. But it can help you write like you already are.

Conclusion

ChatGPT and Gemini helped me build something honest, structured, and profitable – without burnout or ad spend.

I didn’t write this funnel alone. But it still sounds like me. And that’s why it worked.

Would you let AI write your next $100K funnel – if it still sounded like you?
