I've been running Curated Software Deals for years now, and one question keeps popping up in my inbox: "What's the best newsletter tool for someone like me?" As a solopreneur myself, I get it. You need something that doesn't require a marketing degree to operate, won't drain your budget, and actually helps you build relationships with your audience.
After testing dozens of platforms and helping hundreds of founders choose the right one, I'm sharing what actually works in 2026.
The Newsletter Tool Landscape Has Changed
Remember when your only options were ConvertKit, Substack, and MailChimp? Those days are long gone. The market has exploded with tools specifically built for creators, founders, and solopreneurs. The catch? Not all of them deserve your attention.
The best newsletter tools for 2026 share three things: they're simple to use, they don't charge based on subscriber count (a killer for growth), and they integrate with the other tools you're already using. I've learned this the hard way after switching platforms three times.
Substack Still Owns Simplicity
Let me be direct: Substack remains the easiest newsletter platform to start with. No design skills needed. No integrations to configure. You write, you hit publish, and your subscribers get an email. Done.
The revenue split model (you keep 90% of paid subscriptions) is genuinely generous. And the discovery algorithm—flawed as it is—can actually send subscribers your way organically. That's rare in this space.
The downside? Limited customization, no automation, and you're betting on their platform staying relevant. For pure newsletter simplicity, though, Substack is still the default choice for most solopreneurs.
Beehiiv for Growth-Focused Founders
Beehiiv is what happens when someone actually uses the product they're building. The interface feels premium without being complicated. Their referral feature is ingenious—it genuinely works for growth.
What impressed me most: their analytics dashboard. You don't just see open rates. You see which sections readers engage with, what time they open emails, even which links they click. That data is gold for a solopreneur trying to improve their craft.
The pricing stings if you hit high subscriber numbers, but there's a free tier that lets you test drive it. I recommend Beehiiv if growth is your primary metric.
Ghost for the Technical Founder
Ghost occupies a weird middle ground. It's technically a blogging platform, but its email capabilities rival dedicated newsletter tools. If you want to own your audience completely—hosting your own data, controlling everything—Ghost is the answer.
This is for founders comfortable with slightly more setup. But once it's running, you've got a newsletter tool plus a full website, and everything talks to each other seamlessly.
Mailchimp's Underrated Comeback
Mailchimp isn't sexy anymore, but I'd be remiss not mentioning it. For solopreneurs sending under 500 emails monthly, it's genuinely free. The automation has gotten sharper. And if you need to eventually sell products or run ads, the integrations are already there.
I wouldn't build a premium newsletter business on Mailchimp. But as a starting point? It works.
How to Actually Choose
Here's my framework: Start with Substack if you want zero friction and want to focus purely on writing. Choose Beehiiv if you're obsessive about growth metrics. Go Ghost if you're technical and want ownership. Use Mailchimp only if you need maximum integrations and pricing flexibility.

The Real Talk
Your newsletter tool matters far less than your consistency and content quality. I've seen incredible newsletters built on mediocre platforms and empty newsletters on premium ones. The tool is just infrastructure.
Pick one, commit to it for at least three months, and focus on writing something worth reading. You can always migrate later—I've done it multiple times and survived.
If you want to dig deeper into which tool fits your specific situation, head over to Curated Software Deals. We break down not just the features, but the real-world pros and cons based on actual usage. Sometimes the "best" tool isn't the most popular—it's the one that fits how you actually work.
Your next newsletter tool is waiting. Stop overthinking and start publishing.
