Newsletters (Substack/Ghost): How to Use a Carousel to Skyrocket Your Subscribers

Published June 14, 2026 by David

I’ve had my Substack newsletter for 6 months. The result? 42 subscribers. Not exactly a reason to celebrate.

The problem? I was dropping my LinkedIn link like a robot. Zero reach. Algorithms hate off-platform links.

The solution? Turn your newsletter into a trailer using a carousel.

Here’s how I boosted my subscribers by 300% in 3 weeks—without overcomplicating it.

1. The "Trailer" Method (80/20, Not 100/100)

I stopped dumping my entire newsletter on LinkedIn. Why? Because if people can read everything for free, they have no reason to subscribe.

Instead, I pull the most impactful concept from my edition (the one delivering 80% of the value) and turn it into a 7- to 10-slide carousel:

• Slide 1 (Hook): A compelling hook that makes people scroll to the end.
• Slides 2 to 8: Deliver real, standalone value. No frustration, no cheap teases.
• Slide 9 (Transition): "This concept is just one of the 3 strategies I share in my Tuesday edition."

Result? People like, comment, and some click. But most importantly, the algorithm loves it.

2. Don’t Sell "The Subscription"—Sell "The Next Scene"

I tested the classic "Subscribe to stay updated." Result? Zero engagement.

So I changed my approach. Instead of a weak call-to-action, I wrote:

"Want the other 2 strategies + my copy-paste templates? Comment ‘NEWS,’ and I’ll DM you the link."

Boom. 127 comments in 48 hours. My post blew up in the algorithm, and I gained 18 new direct subscribers without lifting a finger.

3. Infinite Recycling (Your Archives Are a Goldmine)

My first edition? It was 3 months old. No one had read it. Yet, it still contained timeless tips that worked.

Now, I turn one old edition into a carousel every week. Zero effort, zero overthinking. Just premium content that converts.

The Ultimate Hack: Automate Your Carousel Creation

Writing a 1,500-word newsletter is already time-consuming. Spending 2 hours in Canva for a carousel? No thanks.

I found CarouselCraft. I copy-paste a paragraph or bullet points from my newsletter, and the AI handles the rest:

• Brain Dump: Condenses text into short, digestible formats.
• Smart-Grid: Generates pro-level slides in 2 clicks.

I publish, collect engagement, and watch my subscriber count take off.
