If you’ve ever looked at your newsletter platform invoice the day after hitting 1,001 subscribers and wondered why your bill jumped $40, you’ve met block pricing. Most newsletter platforms don’t charge you per subscriber—they charge per tier, and each tier is a block.
Cross the threshold by one subscriber, and you pay for the entire next block. The difference between 999 subscribers and 1,000 can be negligible. The difference between 1,000 and 1,001 can cost you an extra $30–$50 per month, depending on the platform.
Here’s how block pricing works, where the expensive jumps happen, and what you can do about it.
How newsletter platform pricing tiers actually work
Most platforms structure pricing in blocks: 0–1,000 subscribers, 1,001–2,500, 2,501–5,000, and so on. You pay a flat rate for each block, regardless of whether you have one subscriber in that tier or five hundred.
Take MailerLite’s pricing as an example. As of mid-2026, the jump from the 1,000-subscriber tier to the 2,500-subscriber tier increases your monthly cost from $15 to $29. If you hit 1,001 subscribers on the first day of your billing cycle, you pay $29 for the month—even though you’re only one subscriber over the line.
Beehiiv follows a similar model. Their Scale plan covers up to 10,000 subscribers at $99/month. At 10,001, you move to the next pricing conversation—often custom, often significantly higher.
ConvertKit’s tiers jump at 1,000, 3,000, 5,000, and 10,000. The shift from 1,000 to 3,000 subscribers takes you from $29/month to $49/month. You’re paying for capacity, not usage.
The most expensive thresholds to watch
Not all tier jumps cost the same. Some are minor bumps; others double or triple your bill.
The 1,000-subscriber threshold is the first major jump for most solo operators. Platforms often offer generous free or low-cost tiers up to 1,000 subscribers, then increase pricing sharply. Crossing from 1,000 to 1,001 can take you from $10–$15/month to $25–$50/month depending on the platform.
The 5,000-subscriber mark is another cliff. At this point, many platforms assume you’re monetising and have budget. Expect monthly costs in the $75–$150 range once you cross it.
At 10,000 subscribers, several platforms (including Beehiiv) move you off public pricing entirely and into custom plans. This isn’t necessarily bad—you may get volume discounts—but it removes pricing transparency and adds negotiation overhead.
Two strategies for managing block pricing
You can’t avoid tier jumps forever, but you can control when they happen and reduce the sting.
Audit and clean your list before crossing a threshold. If you’re sitting at 1,050 subscribers and approaching your billing renewal date, run a re-engagement campaign. Remove unengaged subscribers—those who haven’t opened in 90+ days. Depending on your list health, you might drop back under the threshold and stay in the lower tier for another month or two. This isn’t about gaming the system; it’s about paying only for subscribers who want to hear from you.
Time your growth if you can. If you’re running a launch, promotion, or paid acquisition campaign that will push you over a tier threshold, schedule it right after your billing cycle renews—not right before. Crossing from 980 to 1,200 subscribers two days before renewal means you pay for the higher tier for nearly a full month while barely using the capacity. Crossing two days after renewal gives you the full month to grow into the new tier.
When block pricing actually works in your favour
Block pricing isn’t inherently bad. If you’re growing steadily within a tier, you’re effectively getting a volume discount—your per-subscriber cost decreases as you add people without crossing the threshold.
For example, if you’re paying $29/month for up to 2,500 subscribers, your per-subscriber cost at 1,001 subscribers is $0.029. At 2,499 subscribers, it’s $0.012. You’re paying the same flat rate but serving more than double the audience.
The key is to stay aware of where the cliffs are, plan your growth around them when possible, and keep your list clean so you’re not paying for dead weight.
