Let me share something real with you.
1 year ago, I was lost in the sea of AI announcements. 
Every day, another "game-changing" tool. 

But I noticed something: the truly amazing tools often got buried under all the noise.
That hit home. Hard.

So I started AI Case Study with a simple mission: Give great AI tools the spotlight they deserve.

Today, we're more than just a newsletter. 
We're the bridge between brilliant AI founders and 5K people hungry for real solutions.

Here's what makes our deep dives different:

When your tool gets featured:

Your story reaches 5k engaged readers
You get real impressions from actual interested users
Your solution finds its perfect audience

But here's what really matters...

Each week, I watch founders go from "hoping to be noticed" to "can't keep up with demo requests." 
All because they finally got their story in front of the right people.

The best part? 

This isn't just business. 
Between deep dives, I share all my growth lessons openly. 
Building something meaningful is better when we grow together.

Is your AI tool ready for its moment?
DM "AI TOOL" and let's show the world what you've built.

P.S.

How I nearly doubled my open rates (22%  ⇒ 39%).
It wasn’t magic. And it wasn’t better copywriting.
It was purely Deliverability Engineering.

The reality is that Google and Yahoo are getting stricter. 
If you are sending from a generic domain without authentication, 
you are fighting a losing battle.

I broke down my exact process in this visual.
The Beehiiv Advantage:
 ⇒ Clean IP Reputation
 ⇒ Built-in Authentication
 ⇒ Fast Infrastructure

But it only works if you configure it correctly.
I’ve put together a full blueprint on exactly how I set this up.

5 advanced Beehiiv features creators ignore
You think you know Beehiiv.
You don’t.
Most creators use Beehiiv like it’s a simple email tool.
▸It’s not.
▸It’s a full growth engine.
▸If you know where to look.

Here’s what ninety per cent of creators completely ignore.
And why their newsletters stay stuck at the same subscriber count for months.
1. Advanced Segments
Most people blast the same email to everyone.
That’s why their open rate drops.
 I create rule-based segments.
• High engagers
• Cold readers
• Click actives
• Soft bounces
Each group receives a different strategy.
This one move alone can revive a dying newsletter.

2. Magic Links
Creators underestimate this.
One link.
No form.
Auto subscribe.
Perfect for:
 • WhatsApp groups
 • YouTube descriptions
 • Cross promotions
 • Private communities
I have grown hundreds of subscribers with this one feature.

3. Audience Polling
Creator's guess.
I measure.
I place polls in newsletters to understand what readers want next.
The patterns are clear.
You instantly know the next topic, next lead magnet, next offer.
It removes guesswork completely.

4. Automations with Triggers
A one-time welcome email is not a strategy.
It’s laziness.
Triggered flows based on behaviour build a real journey.
▸ Opened an email.
▸Ignored it.
▸Clicked a link.
Came back after 21 days.
Every behaviour sends a different email.
This is how you build loyalty.

5. Boosts Marketplace
Everyone throws money and hopes for magic.
That never works.
I treat Boosts like paid acquisition.
▸Targeting matters.
▸Partner selection matters
▸Placement matters.

Do it right and you get predictable, consistent subscriber growth.
Creators blame the platform.
The truth is simpler.
You are sitting on a jet.
And flying it like a cycle.

🥂 If you want your Beehiiv setup to use these advanced features instead of wasting potential, I can set it up for you end-to-end.
 DM me Beehiiv Pro and I’ll audit your newsletter personally.

Last week I tested one tiny newsletter tweak. My open rate tripled.

Most play the wrong game. Here’s how to win:

Write subject lines that spark curiosity.
Don't use any random subject lines like “Newsletter #17" or may be any line from your newsletter..
That don't goona work

Make them stop scrolling and think, “I need to read this now.”
Unexpected questions, bold opinions, teasers. Curiosity wins.

Use a real sender name.
People open from people, not faceless brands.
Drop the logo. Use your name.

Get send timing right.
B2B? Hit inboxes before 9 am.
B2C? After dinner.
Never just copy “best practices.” Test with your list. Data beats guesses.

Clean your list ruthlessly.(I do it twice a month)
Dead weight kills your metrics.
Remove or re-engage cold subscribers. 
A small, active list destroys a big, dead one.

Deliver actual value.
No fluff.
If there’s no “Aha,” the reader’s gone for good.
Each email should contain a single, powerful idea. 
No clutter.

Preview text is your secret weapon.
Don’t waste it.
Push the value, or finish the subject’s thought.

Open rates don’t rise by accident.
They follow discipline, not luck.
Most newsletters are lazy. Yours won’t be.


P.S. I am Sorrry for that video.. 😂`

How to run a newsletter that grows every week
👇 
Consistency is king, but systems are the kingdom.

​Early on, I spent hours staring at a blank page, guessing what my subscribers wanted.

Sometimes it worked. Usually, it didn't.
​Then I switched from "intuition" to "infrastructure."

​In the inforaphic below, I break down the 4-step framework I use to automate growth and retention:

​Step 1: How to use "Audience Intelligence" so you never run out of ideas.
​Step 2: The specific "Content Architecture" that makes writing 2x faster.

​Step 3: The "Follow-Up Systems" that build loyalty while you sleep.
​Systems always beat hustle.
Systems never burn out.
Systems scale.

The truth?
​Systems always win.
Systems never burn out.
Systems scale.

​I’ve mapped out the full details in the infographic below. 🖼️

​Want to improve your newsletter system?
​I have a checklist that helps you implement these 4 pillars.

​Comment "PDF" below. 👇
​I’ll send you the checklist AND I'll do a quick review of your newsletter landing page.

Everyone wants to start a newsletter.
 But most people never make it past their third edition.
Not because they don’t have ideas.
 But because they lose momentum before it even begins to compound.
The truth?

 Starting a newsletter is the easiest part.
 It’s staying consistent when no one’s reading that separates amateurs from brands.
The first issue feels exciting.
• You hit publish. A few friends open. You feel proud.
• Then week two comes.
• You overthink the topic.
• Week three comes… and silence.

But here’s what nobody tells you.
Your newsletter isn’t just “writing.”
• It’s identity building.
• It’s a slow burn that eventually becomes your loudest proof of expertise.
• Every issue you write is like a digital footprint.
 • One that keeps working while you sleep.
 • One that people binge when they discover you.
 • One that builds trust before your first DM.

That’s the power people miss when they quit early.
If you stay long enough, the compounding begins:
 ↳ One reader shares it with another.
 ↳ One edition gets quoted somewhere.
 ↳ One startup reaches out for collaboration.

Suddenly, you’re not “writing a newsletter.”
 You’re running a media asset with influence.

So here’s how to start right:
• Pick your niche → Talk about something you could explain for hours without research. That’s your content goldmine.

• Choose your home → Beehiiv or Substack. Keep it clean, not fancy. A clear headline beats a perfect template.

• Fix your rhythm → One day to collect ideas, one to write, one to edit. Repeat weekly. Let it become muscle memory.

• Forget virality → In the first month, nobody cares. And that’s your advantage. You get to practice in silence.

• Keep promises to yourself → When you say “weekly,” mean it. Consistency is your invisible marketing budget.

Because the truth is:
Consistency doesn’t just build your audience.
It builds you.
• Your thoughts get sharper.
• Your style gets smoother.
• Your audience starts to feel your rhythm.

That’s when you realize:
This isn’t a writing task anymore.
It’s a personal growth loop that prints credibility every week.
And once you have that… automation becomes your next unlock.
In the next part, I’ll show you exactly how I automated my newsletter system.

From publishing to posting across platforms — without touching a single button.
That’s where the real leverage begins.

The most underrated milestone in newsletters? 
That first 1,000 subscribers.

Forget 10,000. 
Forget six-figure lists. 
Hitting 1,000 is different.

That number is scrappy. 
It’s fans, not browsers. 
Those first 1,000 actually care.

They reply when you get something wrong. 
They forward your emails to a friend. 
They’ll even call out your typos. 
(Been there more times than I want to admit.)

I still remember my first correction email. 
Someone pointed out a typo in the subject line. 
My face went red for five seconds. 
Then I realized... this is the real “building in public” everyone talks about.

You put your thoughts out there, flaws and all. 
No fancy automations. 
No magic growth hacks. 
It’s just you, showing up even when you’re not sure anyone is watching.

Everyone says “consistency is key,” but it’s true. 
I’ve sent newsletters that felt invisible. 
Zero replies, zero likes, tumbleweeds. 
And then, out of nowhere, one person hits reply with a single sentence that keeps me going.

Here’s the wild part: 
When you reach 1,000 subscribers, it’s not actually about the number. 
It’s about a room full of people who choose you. 
They could read a million other things. 
They picked your voice.

So if you’re stuck at 200, or 500, or sitting on 999, don’t stop. 
Nobody remembers subscriber #10,000. 
But you’ll never forget the first person who told you your email sucked-because they cared enough to read it.

Keep writing. 
Keep hitting send.
I am Doing it from last 700 days. (Without fail)

Drop your best (or roughest) early subscriber story in the comments, or connect if you want more real talk. 
I’d love to hear the real stories.

Most newsletters never make it past launch.

Why? It's not the content.

It's weak positioning.

I see it every day.

Newsletters lost in inboxes.
Landing pages that blend in.
Creators stuck with stagnant lists.

It all comes back to poor positioning.

If your newsletter's value isn’t clear and unique, your landing page fails. When your landing page fails, no one subscribes.

But you can fix this.

Here’s my 2-step framework to lock in great newsletter positioning:

Step 1: Craft a Value Proposition

This is your core promise. Spell out:
What you cover.
What readers gain.
Why it matters.

Be specific. Share an outcome, not just a list of topics.

Try this formula:
Every [frequency], you’ll get [topic] so you can [benefit] without [pain point].

Step 2: Name Your Newsletter

Go for clarity and brevity.
3-4 words max.
The name should reveal what you do and who it’s for.

Stop blending in. Start building a newsletter that stands out and brings in subscribers.

I teach this exact process in my newsletter and Linkedin.

Most creators think their newsletter is failing because they need better ideas.
• The truth is simpler.
• They don’t have systems.
• They copy hooks.
• They copy formats.
• They copy trends.
And then wonder why nothing works.
Here’s what actually drives growth in any newsletter, including mine and the ones I manage for clients.

1. The Content System
Most creators sit down and “think” about what to write.
That is why they burn out.
I rely on predictable inputs like:
• Reader questions
• Poll responses
• High performing posts
• AI assisted research
• Competitor gaps
This removes randomness.
Ideas flow every day.

2. The Distribution System
Creators write once and pray it performs.
That is not distribution.
Every edition gets reused across:
 • LinkedIn
 • Twitter
 • Shorts
 • Carousels
 • Quotes
 • Blog snippets
You don’t grow by posting once.
You grow by multiplying one idea into many touchpoints.

3. The Feedback System
Checking open rate is not feedback.
It’s a surface metric.
I track:
• Link behaviour
• Scroll depth
• Segment performance
• Drop off patterns
• Device timing
• Click clusters
This tells me exactly what to change next.
 No guessing.

4. The Automation System
Manual newsletters die.
Automated newsletters scale.
I use:
• Triggered sequences
• Behaviour based follow ups
• Dynamic content blocks
• AI drafted summaries
• Multi step welcome flows

This is how you turn readers into long term subscribers.
Most creators blame the platform.
The real problem is the lack of systems.
If you build systems, your newsletter grows even on your laziest days.
If you don’t, you restart every month.
