Hey rebel solopreneurs 🦸♀️🦸♂️
You have an email course outline sitting there.
Five days of solid content. Clear lessons. Real value.
But your subject lines? Generic. Vague. The kind readers scroll past without thinking.
"Day 1: Getting Started" "Day 2: Important Tips" "Day 3: Next Steps"
Boring kills open rates. And when readers don't open, your course dies in their inbox.
Smart ones turn outlines into 12 subject line options per email in 90 seconds. Each one hooks a different reader type. Bingo.
⛳️ Why this works
Before you send an email course, you need subject lines that stop the scroll.
Without them? Readers see "Day 1" in their inbox and delete. They don't know what's inside. They don't know why they should care. They don't know what problem you're solving.
Manual subject line writing? Hours of second-guessing. "Should I be clever? Clear? Funny? Formal?" You write one. Delete it. Write another. Still not sure.
Here's the thing...
Your subject line is like a storefront sign.
Most creators write the equivalent of "OPEN." Accurate. Boring. Forgettable. Readers walk right past.
But a great sign tells you exactly what's inside and why you should walk in now. "Fresh Bagels Baked Hourly - Grab Yours Before 10 AM."
The 4-step subject line system works the same way. It gives you proven frameworks that answer what every reader asks in 2 seconds. "What's in this for me? Is it worth my time? Can I get results fast?"
When your subject line answers these questions with clarity and a hook, readers don't just scan and delete. They open. They read. They set alarms for the next email.
With the prompts below, you turn your outline into 12 options per email. Each hooks differently. Pick the one that fits your vibe. Send.
Turns out, systematic beats staring at blank subject lines every time.
Let's see how Alex figured this out...

Alex runs an educational email course on productivity.
But here's their problem. Open rates were dying. 7% on most emails. Some days, 4%.
Subject lines looked fine. "Day 1: Introduction" "Day 2: Time Management Tips"
Clear enough, right?
Wrong.
Readers didn't open them. The subject lines didn't promise anything specific. No hook. No reason to click now versus later.
And later? That means never.
Alex tried brainstorming. Spent 3 hours per email testing variations. "Unlock your productivity..." Delete. Too vague. "Master time management..." Delete. Too formal.
Still stuck at 7% opens.
Then Alex found something. A framework from multi-million dollar email marketers. Four steps that turn outlines into high-converting subject lines systematically.
Changed everything.
Alex decided to follow these steps:
Step 1: Train their AI sidekick on the 4 proven hooks Step 2: Feed their email course outline to the framework Step 3: Choose their subject line style preference Step 4: Generate 12 subject line options per email automatically
Step 1: Train on the 4 proven hooks
Alex opened ChatGPT/Claude (their AI sidekick).
They needed subject lines that hooked readers. Not generic "Day 1" labels.
But wait. Which hook works best? Value for time? Value for cost? Instant outcome? Effortless solution?
They had no clue.
Every subject line felt like a guess. Write it. Hope readers click. Check open rates. Repeat.
Here's what they tried...
The subject line framework training prompt
Act like an expert email marketer with 10 years of experience.
You are a master at grabbing people's attention in their email inbox.
I want to write an email subject line and subtext to capture my target audience's attention.
The job of the subject line is to hook the reader (in an informal fashion, like a note to a friend)
The job of the subtext is "Whisper." A "here's what's inside" sentence. (think parenthetical in copywriting)
Here's what we are going to do:
I am going to give you a topic, an audience, and an outline for a 5-Day Educational Email Course.
After I have provided you the topic, audience,and outline, you will ask me: "How would you like preface each subject line?" You will let me know what my choices are.
The subject line preface choices are:
1) Preface the subject with "Day #:", like "Day 1:" for Day 1 in the course.
2) Name & Claim an idea. Like "Life Coach Money Manual:"
3) No preface
Once you have everything you need, you will create 3 email subject lines with a corresponding subtext line for each type of the 4 proven hooks for each day in the Email Course.
You will write the subject lines and subtext 1 day at a time, starting with the 1st day.
Here are the 4 proven hooks:
1. A ton of value for minimal time.
2. A ton of value for minimal cost.
3. How to solve your problem without much effort.
4. How to unlock a desirable outcome, instantly.
Some good subject line example to follow:
- "Your entire Life Coach career path blueprint… in 1 email!"
- "Here's our entire $1M marketing plan. Steal it!"
- "Losing money in the stock market? Just buy these 3 companies."
- "3 keys to land $10,000 consulting clients, from home, in your pajamas, right now."
- "5 steps to write your first viral Twitter thread as a Digital Creator (even if you have 0 Followers)"
The things you can "whisper" are:
- A "trust me" sentence
- A "without this obstacle" sentence
- A "and with this additional benefit" sentence
- A "and so you can achieve this outcome too" sentence
For example:
- Trust Whisper = "Written By A Twitter Creator With 100k Followers"
- Obstacle Whisper = "Without Spending Any Money On Ads"
- Benefit Whisper = "And How To Solve It"
- Outcome Whisper = "And Start Earning $250,000 Per Year In Your Sweatpants"
Here's is and example of what your output will look like for each subject line and pretext you create:
- "Subject Line 1 (Value for Time): Avoid 3 common Twitter pitfalls in minutes."
- "Subtext (Outcome Whisper): And save months of misguided effort."
A few rules:
- Rule #1: Use 15 words, max.
- Rule #2: The subject line should read like you're talking to a friend. (use sentence case)
- Rule #3: Use visceral TANGIBLE language
- Rule #4: Intrigue the reader
- Rule #5: Use numbers
- Rule #6: Be SUPER SPECIFIC
Remember: DO NOT exceed the word count limit for effective subject lines.
Let me know when you are ready for topic, the outline and the audience.
Their AI sidekick returned a confirmation. Ready to receive the course details.
Alex had the framework loaded. Now they needed to feed it their specific content.
Step 2: Feed the email course outline
Alex had the framework. But it needed specifics.
Which course outline? What audience? What transformation?
Generic training without context? Generic subject lines. Alex needed options tailored to their productivity course.
Here's what they did...
The content feeding prompt
Topic = 5-day "Crash Course" on how to get started writing on Twitter
Audience = Beginner Writers
Outline =
- **Day 0: Introduction & Email Course Outline - "Here's what you can expect"**
- Introduction to the email course and what participants can expect to learn.
- Overview of the 5 things that will be covered in the course.
- **Day 1: 3 Most Important Things To Know**
- Teach, Don't Entertain
- You Should Aim To Post 2-3x Per Day
- The Secret Is To Niche Down
- **Day 2: 3 Mistakes Most People Make**
- Trying To Write For "Everyone"
- Failing To Double-Down On Your Winning Topics
- Giving Up After 30 Days (Or Less)
- **Day 3: 3 Steps To Go From Zero to 1**
- Name & Claim Your Niche In Your Bio
- Turn Your Best Tweets Into Threads
- Respond To Every Single Comment
- **Day 4: 3 Simple Upgrades To Accelerate Growth**
- Upgrade Your Bio Headshot & Banner Photo

- Review Your Analytics Once Per Month
- Once You Find A Winning Topic, Repeat It (Endlessly!)
Their AI sidekick analyzed the outline. Asked for subject line style preference.
Alex was ready for the next decision.
Step 3: Choose subject line style
Alex had a choice to make.
Should they preface each email with "Day 1:" so readers track progress? Or use "Name & Claim" style to make each email feel like a complete asset? Or skip prefacing entirely?
Each style hooks differently. "Day 1" creates sequence momentum. "Name & Claim" makes emails feel valuable standalone. No preface maximizes curiosity.
Here's what they tried...
The style selection prompt
I'd like to use Name & Claim style. Make each email subject line feel like a complete manual or guide the reader is receiving.
Their AI sidekick confirmed the choice. Ready to generate subject lines with the "Name & Claim" approach.
Now came the magic.
Step 4: Generate 12 options per email
Alex had everything loaded. Framework trained. Content fed. Style chosen.
But they still needed the actual subject lines. Not just one or two guesses. They needed options. Multiple angles. Different hooks.
Here's what they did...
The generation prompt
Generate all subject lines and preview text for Day 1 of the course.
Their AI sidekick returned 12 subject line options for Day 1:
The beginner writer's manual: 3 things you must know before posting
Twitter writing starter pack: Teach, niche down, and post 2-3x daily
New writer's quick-start: 3 rules that actually matter on Twitter
The 3 non-negotiables: What every beginner writer needs to know first
First-week Twitter blueprint: Teach your expertise, not entertainment
The beginner's clarity guide: 3 things to know before you post once
New to Twitter writing? Start here: 3 things that matter most
The writer's foundation: Teach, niche, and post consistently from day one
Twitter writing essentials: 3 rules before you write your first post
Smart writer's checklist: Know these 3 things before posting anything
The 3-point starter: What beginners must know to succeed on Twitter
New writer roadmap: Teach expertise, niche down, post 2-3x daily
Each with preview text like "Without wasting months on trial and error" or "And start growing from post one."
Not bad.
Alex copied this. Repeated for Days 2-5. Each day got 12 fresh options tailored to that day's lesson.
Done.
