Newsletter platforms that don't charge per subscriber

If you've watched a newsletter grow past a few thousand subscribers on any of the major platforms, you've noticed the same thing: the price chart bends sharply upward. Mailchimp at 5,000 subscribers is around $75 a month. ConvertKit hits $79 at 7,500. Beehiiv, MailerLite, Brevo — they all follow the same pattern. The bigger your list, the more you pay, regardless of what you actually do with it.

This is so normal that nobody questions it. But the pricing model doesn't actually match what makes a newsletter expensive to run.

What actually costs money

Storing a subscriber costs essentially nothing. A row in a database plus a few bytes of metadata. You could store a million subscribers for the price of a cheap VPS.

Sending an email costs money. SMTP infrastructure, deliverability monitoring, bandwidth, support for bounce handling — that's real spend. A newsletter sent to 10,000 people once a week costs the platform far more than the same list sitting idle.

So pricing per subscriber is a proxy for pricing per email, except it's a bad proxy. A 50,000-subscriber newsletter that emails monthly costs less to deliver than a 5,000-subscriber list that emails three times a week. The per-subscriber model overcharges the first one and undercharges the second.

The reason platforms do it anyway is simple: list size is easy to measure, predictable to bill against, and scales reliably with the customer's perceived value. It's not unfair so much as imprecise.

The flat-pricing alternatives

A handful of platforms have moved away from per-subscriber billing. They fall into three camps.

Self-hosted. Listmonk is the standard option. You pay for your server and your SMTP provider, no per-subscriber escalation. The catch is that you're also signing up for the operational work, which is more than the tutorials suggest. Worth it if you enjoy infrastructure, expensive in time if you just want to write.

Managed but flat. A few platforms cap things on email volume rather than subscriber count. EmailOctopus is the cheapest in this category — they use AWS SES under the hood and price aggressively. Buttondown is similar, more writer-focused, slightly more expensive. Both let you keep large lists without the price spiking just because the list grew.

The Substack model. Free to use, takes 10% of paid subscriptions if you monetize. No per-subscriber charge. But you don't own the platform, the audience lives inside Substack, and if you ever want to leave you take your email list and start over from scratch. Free is rarely free.

The honest trade-off

Flat pricing has to come from somewhere. The platforms that don't charge per subscriber pay for their infrastructure by capping something else — usually monthly email volume.

That's the trade. A flat-priced platform tells you up front: "you can have any number of subscribers, but you can send at most X emails this month." When you hit the cap, sending pauses. You either wait until next month or upgrade to a higher tier.

If your newsletter sends weekly to a stable list, this works out cheaper than per-subscriber pricing. If you suddenly need to send to your whole list five times in a week, you'll hit the cap and either pause or pay more.

The per-subscriber model spares you that decision but makes you pay for it whether you send or not. Pick the one that matches your sending pattern.

What we charge

This is the part where we're transparent about Yellaro. We run managed Listmonk hosting and we use email-volume caps instead of subscriber-count tiers. Starter is €12 a month for up to 5,000 emails. Scale is €99 for up to 75,000 emails. You can have a million subscribers on Starter — what we limit is what you send.

If you hit the cap, sending pauses for the rest of the billing cycle. We don't bill overages. We don't surprise you with a usage invoice at the end of the month. Predictable cost in, predictable behavior out.

Whether that pricing shape works for you depends on how often you send. If you publish weekly to a list of 20,000 subscribers, you're at around 80,000 emails a month — that's the Scale tier on Yellaro, or roughly the same on EmailOctopus, or about double on Mailchimp because they price by list size not send volume.

The right platform isn't the cheapest. It's the one whose pricing matches how you actually use it.
