Choosing the right email publishing software comes down to a simple financial fork in the road. Pick Substack if you want a zero-cost setup with a built-in social network. Pick beehiiv if you want total control over your design, flat-rate pricing, and advanced growth tools.
Most online reviews gloss over the math or pretend one option fits every creator. They don't. Substack takes a percentage of your earnings, while beehiiv charges a flat subscription fee. Your choice depends entirely on how many paid subscribers you have, how you plan to find new readers, and whether you want your own independent domain.
Pricing Models: Flat Fee Versus Revenue Share
The most glaring difference between these tools is how they make their money from your work.
Substack charges nothing upfront. You can publish text, build a massive list of free subscribers, and send weekly emails without ever entering a credit card. The catch arrives the moment you turn on paid subscriptions. Substack takes a flat 10 percent cut of every dollar your paying readers send you, plus standard payment processing charges via Stripe.
beehiiv flips this structure upside down. It offers a free tier for up to 2,500 contacts, but if you want advanced features or to run paid subscriptions, you move to a paid monthly or annual plan. The vital detail: beehiiv takes zero percent of your subscription revenue on its Scale and Max tiers.
The Break-Even Math
Let's look at real numbers. If you charge $10 a month for your newsletter, Substack takes $1 per subscriber every month. If you reach 100 paying subscribers, you are handing Substack $100 monthly.
beehiiv's Scale plan charges a flat fee depending on your total subscriber count. Once your paid subscription revenue crosses roughly $400 to $500 a month, beehiiv's flat fee often becomes cheaper than Substack's 10 percent tax. If you scale up to 1,000 paying subscribers at $10 each, Substack takes $1,000 every single month. beehiiv's flat fee stays the same based on tier size, leaving thousands of extra dollars in your bank account annually.
Growth and Discovery Mechanics
Getting people to read your work is hard. The platform you choose changes how your audience finds you.
Substack acts like a publishing network. It features a built-in recommendation engine, a Twitter-style social feed called Notes, and a dedicated mobile app where users browse multiple publications. Many writers pick Substack purely because getting recommended by a larger publication inside the network can bring in hundreds of subscribers overnight without paid advertising.
beehiiv approaches growth through data and structured marketing funnels. It includes built-in referral programs, recommendation loops called Boosts, and audience segmentation tools. You get deep analytics on open rates, click tracking, and subscriber behavior. If you prefer running automated welcome sequences and testing different subject lines to optimize your open rates, beehiiv provides those controls. Substack keeps its editor intentionally bare-bones, offering minimal styling choices and no native A/B testing.
Design Customization and Branding
Your digital home should look like your brand, not a template owned by a tech startup.
Substack publications look remarkably similar. While you can change accent colors and upload a logo, your archive lives on a subdomain, and every page carries subtle Substack branding. Unlocking a fully custom domain on Substack requires a one-time fee, and you still operate within their rigid layout framework.
beehiiv treats your newsletter archive like a full content website. You can edit site architecture, configure SEO meta tags, and build custom landing pages. On higher tiers, beehiiv removes its platform branding entirely, giving you a white-label publication that looks and feels like an independent media company.
Common Mistakes Writers Make When Choosing
- Choosing Substack just because it is free at zero revenue: While true, sticking with a 10 percent revenue share becomes painful the moment your publication gains traction. Calculate your projected earnings for year two before committing.
- Ignoring the distribution reality on beehiiv: beehiiv gives you incredible tools, but it won't drop readers into your lap the way Substack Notes can. If you have no social media following and no marketing plan, starting on beehiiv requires more outbound effort.
- Failing to check migration paths: Moving from Substack to beehiiv later is straightforward, but it takes time. Stripe accounts transfer over cleanly, yet updating links and checking form integrations causes friction if done hastily.
Frequently Asked Questions
Can I migrate my paid subscribers from Substack to beehiiv without losing billing?
Yes. Both platforms integrate with Stripe. When you migrate your list to beehiiv, you can reconnect your existing Stripe account so your active paying subscribers experience zero interruption in their billing cycles.
Which platform is better for running sponsorships and ads?
beehiiv is built for ad monetization. It features a native ad network that connects newsletter operators directly with brands looking for sponsorship space. Substack allows manual sponsorships, but it lacks an automated internal ad marketplace.
Do I need technical skills to set up custom domains?
Neither platform requires coding, but beehiiv offers more granular control over your website architecture. Connecting a custom domain on either service simply requires updating a few DNS records with your domain registrar.
Is beehiiv's free tier enough for a beginner?
beehiiv's Launch plan lets you grow up to 2,500 subscribers for free. However, automated welcome emails, advanced analytics, and paid subscriptions require upgrading to a paid tier. If you just want to send basic weekly essays without spending money, Substack remains free at any subscriber count.
