Solo ads are a fast way to generate traffic, but what really makes or breaks your results is the email follow-up. After someone opts into your funnel, your email copy decides whether they convert — or disappear.
For years, I wrote all my follow-ups manually. I was decent at it. But then I tried something new:
I swapped my entire sequence for GPT-AI email follow-ups — and my solo ad conversions tripled.
In this post, I’ll break down exactly what I did, the prompts I used, how the AI-written emails performed, and why this may be the easiest upgrade you can make to any funnel today.

Why I Switched to GPT-AI Email Follow-Ups
Solo ads are mostly cold traffic. They don’t know you, don’t trust you — and usually don’t open your emails.
At best, I was getting:
- 28–32% open rates
- 6–8% click-throughs
- About 3–4% sales from opt-ins
But my follow-ups felt repetitive. I was spending too much time writing — and not enough testing. That’s when I realized I could use GPT-AI email follow-ups to scale my testing faster and improve performance.
GPT-AI vs Human Copy: My Test Setup
I created a simple A/B test:
- Same offer
- Same solo ad vendor
- Same landing page and opt-in form
- Split leads into two groups:
- Group A: My original human-written 5-day email sequence
- Group B: AI-generated 5-day sequence using ChatGPT
I used GetResponse for email automation, ClickMagick for tracking, and Systeme.io as my funnel builder.
My GPT-AI Prompt for Email Sequences
Here’s the exact ChatGPT prompt I used to generate my follow-up emails:
“Write a 5-day email sequence for new leads who downloaded a free crypto checklist. The tone should be friendly, curious, slightly informal, and designed to build trust. Include light storytelling, simple CTA links, and no hard-selling.”
GPT generated 5 solid emails in less than 2 minutes. I tweaked a few lines, added personalization, and set them live.
The GPT-AI Email Follow-Ups Funnel
The offer was a free PDF:
“Crypto Starter Checklist: 5 Mistakes Beginners Make + How to Avoid Them”
Follow-up sequence goals:
- Build trust
- Offer helpful insights
- Drive clicks to a low-ticket offer ($27 crypto training)
- Segment clicks into a higher-ticket backend
Performance Comparison (Human vs GPT-AI)
Here’s what surprised me most…

🧮 Conversions After 5 Days
- Human Copy: 3 sales out of 100 leads
- GPT-AI Copy: 9 sales out of 100 leads
That’s a 3X improvement using GPT-AI email follow-ups — without extra traffic or ad spend.
Why GPT-AI Follow-Ups Work So Well
✅ 1. Faster Testing
I was able to create multiple email variations in minutes, not hours. This let me test new angles without writer’s block.
✅ 2. More Storytelling
GPT naturally weaves curiosity and emotion into its messages. It uses story frameworks and soft CTAs that work well for cold leads.
✅ 3. Cleaner Layout
The AI didn’t overload the reader. It used:
- 1 clear message
- 1 main CTA
- Short paragraphs = mobile friendly
✅ 4. Personalized Tone
Once I fed it a few of my past emails, GPT mirrored my style pretty well. With minimal edits, it sounded like “me” — but better.
