What's Your Newsletter Actually Worth?

For the last two weeks I've been digging into something that's a bit outside my usual territory buying and selling newsletters. Don't worry, I'm not planning to sell this one anytime soon, so everything you've shared with me stays safe between you, me, and our ESP.

But I got genuinely curious. I started researching across different channels Email Geeks community, Beehiiv forums, Reddit threads — and what surprised me is how little useful information is actually out there. There are a handful of marketplaces where you can list a newsletter or browse what's available, but the conversation around what you're actually buying or selling is pretty thin. What makes a newsletter valuable? How do you know you're buying something real and not just an email list with a landing page on top? What's even the difference between buying a newsletter and buying a list — and why does that difference matter?

Those questions sent me deeper, and here's what I found.

When people list newsletters for sale, they almost always lead with subscriber count and open rate. And when buyers respond, they're often reacting to those same numbers. But subscriber count and open rate are not value. They are potential and potential doesn't pay for itself.

Think about it like buying a coffee shop. You wouldn't make an offer based on how many people walk past the window every day. You'd want to know how much money it actually makes, where that money comes from, and whether it keeps coming in after you take over. Newsletters are no different, but for some reason that logic gets abandoned the moment someone puts a subscriber count in the listing.

Revenue is what you're buying. And how that revenue is generated matters just as much as how much of it there is. A newsletter that earns entirely through an ad network it doesn't control is a different investment from one with direct advertiser deals or paid subscriptions. The ad network can change its rates, change its terms, or disappear. You have no say in any of that. Multiple revenue streams, or at least one the owner actually controls, makes for a more durable asset and that durability should be priced in.

Paid subscriptions feel safer because the revenue is predictable and recurring. But they come with their own question: are people paying for the content, or for the person writing it? If the answer is the person, then the newsletter is worth considerably less the day someone new takes over.

Ask the seller directly: have you ever taken a break from writing? What happened to open rates? The answer will tell you everything about whether the audience is loyal to the content or to them personally.

And then there's something that almost never comes up in these conversations who the subscribers actually are. A list is not a list. 10,000 senior decision-makers at B2B companies is a completely different asset from 10,000 people who signed up during a giveaway. The more first-party data exists what readers do, where they work, what they're responsible for the more clearly a seller can communicate real value, and the more confidently a buyer can make a decision. The right buyer also matters. The same newsletter can be worth almost nothing to one person and a lot to another, depending on what they already own and how they want to use the audience.

I built a calculator to help make sense of all this. It looks at revenue type and stability, engagement quality, subscriber data depth, and niche — and gives you a realistic starting point for understanding what a newsletter is actually worth before you walk into any conversation about buying or selling one. I'm getting ready to launch it soon and I'd love for you to be among the first to try it. If you have any feedback after testing it, just hit reply — I'd genuinely appreciate it.
