The Better Marketing Blog

Writing a weekly marketing newsletter is one of the most high-leverage content activities a company can do. But writing high-performing content consistently? That’s the hard part.

At Media Shower, we use our own AI marketing platform to streamline the process. What used to take hours now takes about 20 minutes—without sacrificing quality or creativity.

Our results speak for themselves. Since we started using this AI-assisted approach, our newsletter has steadily climbed the Google search rankings, driving more visibility, traffic, and subscriber growth.

In this post (and the demo video below), you’ll see exactly how we do it – and how you can, too. 

Step-By-Step Guide

Here’s how we use AI to create our popular weekly marketing newsletter.

Step 1: Use a proven format

Each of our newsletters opens with a quote and image from pop culture (think “Spider-Man,” “Star Wars,” or “The Godfather”). We then connect the quote to a relevant marketing idea. 

The result is a punchy, memorable piece—usually around 250 to 300 words. We borrowed this format from Byron Gilliam at Blockworks, and it works.

Step 2: Open the Media Shower AI platform

Our AI platform already knows our brand, voice, and audience, so we start with a prompt like:

Prompt: Help me write a column about how to use AI to write newsletter columns. Start with a well-known quote from a movie or TV show. Give me five options.

From there, we choose the best one. For this demo, we picked Spider-Man. Then we give the AI a few high-level talking points.

Step 3: Train it on your voice

 To get the tone just right, we paste in a previous newsletter:

Prompt: “Here’s a recent column for tone, length, and style.”

This teaches the AI how we write, so the draft it returns is in our voice. A few tweaks later, we have a polished, publishable piece.

Step 4: Polish with human creativity

At this point, AI has done 80% of the work. We now add the final 20% by fine-tuning the language, adding clever wordplay, and making the final edits. 

In about 20 minutes, we have:

• A compelling pop culture quote and photo
• A tight intro
• Real marketing metrics
• An explanatory video
• And a punchy closing line

Why This Newsletter Strategy Works

This format works because it does three things:

• Hooks attention with a familiar pop culture reference
• Delivers value by connecting it to a timely marketing insight
• Drives engagement by being short, punchy, and easy to read

It’s a proven storytelling formula that combines emotional resonance with practical relevance—perfect for B2B and B2C audiences alike.

Tips for Creating AI-powered Newsletters

Here are a few things we’ve learned.

• Reuse proven formats. Create a newsletter template that works, and let AI help you fill in the details each week.
• Start with strong prompts. Give the AI a clear idea: theme, format, and tone.
• Feed the AI your past work. This helps the platform learn your voice.
• Punch up the draft. Use human creativity to turn a good draft into a great piece.
• Use metaphors. AI loves structure—start with a metaphor (like Spider-Man) to tie it all together.

Real-world Example

Let’s look at how Skyward Growth, a fictional SaaS company, uses Media Shower’s AI platform to create its weekly newsletter.

Scenario: Kayla, Skyward’s VP of Marketing, wants to write a newsletter on the theme of balancing automation with human touch. She uses the Media Shower platform to get started.

Prompt: “Help me write a newsletter column on using AI in customer service. Start with a quote from a sci-fi movie. Give me five options.”

AI Response:

“Here are five quotes you can use:

• ‘I’ll be back.’ – The Terminator

• ‘Danger, Will Robinson!’ – Lost in Space

• ‘The needs of the many outweigh the needs of the few.’ – Star Trek

• ‘Open the pod bay doors, HAL.’ – 2001: A Space Odyssey

• ‘Resistance is futile.’ – Star Trek: The Next Generation”

Kayla selects #3 and prompts the AI further:

Prompt: “Tie this quote into the idea that while AI helps us serve more customers, the human element still matters. Make it concise, informative, and end with a CTA for our product trial.”

AI Response:

[Returns a solid draft with a powerful metaphor about Vulcan logic and the value of empathy.]

Kayla pastes in a previous column to match tone and then edits the draft for punch and style.

In under 30 minutes, she’s got a newsletter that’s informative, on-brand, and ready to send.

Advanced Prompt Engineering Tips

To take your newsletter content even further:

• Include tone guidance like “make it witty” or “add a touch of sarcasm.”
• Ask for alternate takes to A/B test intros or closing lines.
• Request content in multiple formats, like email and blog post, to repurpose your draft across channels.

Treat AI like your brainstorming partner and content strategist rolled into one.

Performance Metrics to Track

To evaluate the performance of your AI-assisted newsletter, track:

• Open rate: A good quote + subject line combo can increase curiosity.
• Click-through rate (CTR): Tie your content to a strong CTA.
• Subscriber growth: A well-formatted, engaging newsletter gets shared.
• Engagement time: Tools like heatmaps or scroll depth show how long people stay with your content.

Marketer Takeaways

• Create a repeatable newsletter structure to save time and boost consistency.
• Use AI to accelerate ideation and drafting—but keep your human voice front and center.
• Train your AI with past examples to stay on-brand.
• Think of AI as your writing partner. Let it handle the heavy lifting, then add your own creative touches.
