Hi 👋🏻
As I mentioned last Saturday, Insideletter will totally focus on the monetisation aspect of newsletters.
So this is day 1 of the change
So in the next few editions, I’ll talk about the basics of monetisation and clear some obvious terms for you! In today’s edition, let’s talk about revenue models.
Difference between revenue model and monetisation ways
Newsletter revenue model and newsletter monetisation ways are not the same thing, although people often use them interchangeably.
A newsletter revenue model is the overall structure of how the newsletter fits into your business and generates income. It defines the core of your income engine.
A newsletter monetisation way is a specific method you use to generate money within that model.
Think of the revenue model as the blueprint. Monetisation ways are the tools you plug into that blueprint.
For example, look at Morning Brew (or your favourite Insideletter). Their revenue model is advertising-driven media. Their main monetisation way is selling sponsorship placements inside the newsletter.
Now look at Justin Welsh. His revenue model is creator-led education and personal brand leverage. His monetisation ways include selling digital products, courses, and using affiliate links through his newsletter.
So the difference is this:
Revenue model answers: What type of business am I building?
Monetisation way answers: Exactly how am I creating money?
If you see how I built Insideletter, you’ll be able to understand that the goal is a one-person standalone newsletter business, getting this distinction right matters.
You first decide whether you are building a media company, a paid community, a product-led business, or a services funnel. Then you choose the monetisation methods that support that structure.
Types of revenue models
A newsletter revenue model is the overall business structure that explains how your newsletter generates income in a sustainable way.
When you choose a revenue model, you are deciding what role your newsletter plays in your business and where the money ultimately comes from.
There are a few main newsletter revenue models.
Advertising-driven media model
In this model, the newsletter itself is the product. You grow a large and specific audience, and brands pay you to access that audience. Companies like Morning Brew operate this way. Revenue increases as your audience and their quality grow.
Paid subscription model
Here, readers pay directly for premium content. Platforms like Substack popularised this approach. The newsletter content is the core product, and income comes from recurring subscriber payments.
Product funnel model
In this structure, the newsletter builds trust and authority, and you sell products to your audience. Creators like Justin Welsh use this model. The newsletter drives sales for courses, digital products, or communities. The newsletter is the distribution engine, not the final product.
Services-led model
Here, the newsletter nurtures potential clients who later hire you for consulting, coaching, or agency services. The newsletter builds credibility and warms up high-value leads.
Hybrid model
Many advanced newsletter operators combine models. For example, they might run sponsorships while also selling products, or combine subscriptions with consulting. (Insideletter’s future is this)
The key difference between revenue models is that each model changes how you grow, what you optimise for, and how you position your newsletter.
Which one should you choose?
Choose based on who you are
Not every model fits every person. If you enjoy working closely with people, a services-led model can be a good fit. If you prefer creating once and selling many times, a product-based model may suit you better. If you like writing deep analysis and building loyal readers, a subscription model can work well. The goal is to pick a structure that supports your personality.Choose based on your stage
If your newsletter is small, focus on models that do not require massive scale. Selling services or a focused product often works better than chasing sponsors too early. As your list grows, you can experiment with ads or premium tiers. Your size matters because some models need volume to make sense.
Choose based on math
If you have 2000 subscribers and even one per cent buys a £500 offer, that will be enough. If you depend on sponsorships with that same list size, the returns may be lower unless your niche is highly valuable. Let numbers guide you instead of copying what looks attractive online.
Your model shapes everything
An advertising model pushes you to grow fast and increase reach. A subscription model pushes you to go deeper and strengthen loyalty. A product funnel pushes you to build authority and trust. A services model pushes you to show proof and outcomes. Your revenue model influences how you write and what kind of readers you attract.
Let me show some math
If 1% of your total list buys a £1,000 service in a year, that is 50 clients.
50 × £1,000 = £50,000 all'anno.
Imagine 5% of your 5,000 subscribers upgrade to a paid tier at £10 per month.
That is 250 paying members.
250 × £10 = £2,500 per month.
Over a year, that equals £30,000, assuming you manage churn properly.
With 2,000 opens per issue, you might charge based on cost per thousand opens.
If you charge £30 per 1,000 opens, then 2 × £30 = £60 per issue.
If you send 12 issues per month, that is £720 per month.
Over a year, that equals £8,640.
One last thought
Now that we have covered the models and the math, here is something you should understand.
Every revenue model comes with a trade-off.
A services model can generate high income with a small list, but revenue depends heavily on you and your time. A paid subscription model creates recurring income, but you must consistently deliver value and manage churn. An advertising model scales with audience size, but income fluctuates with reach and market conditions. A product model offers leverage, yet revenue can feel uneven if you rely only on launches.
There is no perfect model. There is only one that fits your strengths, your stage, and your goals.
