Newsletter publishers on beehiiv alone sent 28 billion emails in 2025 and reached more than 255 million unique readers, with average open rates climbing to 41.24% from 37.98% a year earlier (beehiiv, State of Newsletters 2026). Paid subscriptions on that platform generated $19 million in 2025, a 138% jump from $8 million in 2024, and are projected to reach $35 million in 2026 (beehiiv, State of Paid Newsletters 2026). On Substack, more than 5 million paid subscriptions and a $1.1 billion valuation signal that the format has matured from side project to media category (Backlinko, Substack Statistics 2026). Meanwhile, the share of Americans unwilling to pay for any publisher content fell from 72% in 2021 to 61% in 2026 (CivicScience, 2026 Publisher Subscription Landscape). This analysis consolidates data from beehiiv, Substack, Litmus, CivicScience, the Reuters Institute, and 10 other primary sources spanning engagement benchmarks, monetization, ad rates, audience demographics, and AI adoption.

1. Engagement and Open-Rate Benchmarks
Reported open rates look healthy, but the headline number hides a measurement problem. beehiiv’s network average reached 41.24% in 2025, up from 37.98% in 2024 (beehiiv, State of Newsletters 2026) - yet Apple Mail Privacy Protection auto-loads tracking pixels whether or not a human reads the message, inflating opens by an estimated 15-20 points. Since Apple accounts for roughly half of all opens, the practical takeaway is to treat click-to-open rate, not raw opens, as the real engagement signal. Day-to-day open variance on beehiiv is tiny (about 0.31% on average, biggest spread 1.04%), so obsessing over send-time optimization rarely moves the needle for lists under a million (Ethan Brooks, Thoughts on beehiiv’s 2026 Report).
| Metric | Value | Source |
|---|---|---|
| Newsletter open rate, 2025 network avg | 41.24% | beehiiv, State of Newsletters 2026 |
| Newsletter open rate, 2024 | 37.98% | beehiiv, State of Newsletters 2026 |
| Curated creator newsletter open rate range | 35-50% | Prospeo, Newsletter Open Rates 2026 |
| Publishing industry open rate | 34.24% | Mailchimp, Email Marketing Benchmarks |

| Cross-industry unsubscribe rate per send | ~0.22% | ClickMinded, Newsletter Statistics 2026 |
| beehiiv Boosts subscriber acquisition, avg | 84/month | Ethan Brooks, beehiiv 2026 Analysis |
Outlier: welcome emails on beehiiv open at 47%, and venture-capital newsletters top the category chart at 50.4% (beehiiv data via Whop). Retail and e-commerce newsletters sit lowest at 16-20%.
2. Paid Subscriptions and Conversion
The paid-newsletter economy is real but brutally concentrated. The platform-wide free-to-paid conversion median is just 0.62% (beehiiv, State of Paid Newsletters 2026) - meaning a typical list converts fewer than 1 in 150 free readers. The winners are in money-adjacent niches: the top 10% of economy lists convert 30.8% and finance lists around 20%, because readers treat those subscriptions as an investment expense rather than entertainment. Pricing has been remarkably stable, anchored at $10/month and $100/year since 2024, while the shift from monthly to annual billing mid-2025 signals publishers optimizing for predictable revenue over raw signups.
| Metric | Value | Source |
|---|---|---|
| Free-to-paid conversion, platform median | 0.62% | beehiiv, State of Paid Newsletters 2026 |
| Free-to-paid conversion, top 10% economy lists | 30.80% | beehiiv, State of Paid Newsletters 2026 |
| Median monthly price (market standard) | $10 | beehiiv, State of Paid Newsletters 2026 |
| Median annual price (market standard) | $100 | beehiiv, State of Paid Newsletters 2026 |
| Healthy free-to-paid benchmark (engaged lists) | 5-10% | ConvertKit (via Whop, 2026) |
| Subscriber lifetime value range | $83-$230 | beehiiv, State of Paid Newsletters 2026 |
| Median time to first paid tier after launch | 45 days | beehiiv, State of Paid Newsletters 2026 |
| Money-niche monthly churn (highest) | 16.67% | beehiiv, State of Paid Newsletters 2026 |
Context: at 5,000 subscribers using median conversion and pricing, an investing newsletter projects to roughly $13,600/year versus $1,260 for travel - an 11x spread driven entirely by niche. See our creator economy statistics for how this compares to other monetization models.
3. Newsletter Advertising and Sponsorship Rates
Advertising, not subscriptions, is where mid-size newsletters make most of their money - and rates scale with audience quality, not just size. A list of 10,000 engaged subscribers earns $2,000-8,000 per month from ads (Influencers Kit, Newsletter Ad Rates 2026), while niche determines the ceiling. B2B, SaaS, and finance audiences command the richest CPMs because a single qualified reader can be worth thousands to the advertiser; creator and lifestyle lists earn a fraction of that per impression. The structural shift for 2026 is the migration from CPM toward CPA - the highest-earning lists increasingly charge for clicks or qualified signups rather than raw opens.
| Metric | Value | Source |
|---|---|---|
| Monthly ad revenue at 1,000 subscribers | $200-500 | Influencers Kit, Newsletter Ad Rates 2026 |
| Monthly ad revenue at 10,000 subscribers | $2,000-8,000 | Influencers Kit, Newsletter Ad Rates 2026 |
| B2B SaaS CPM (per 1,000 opens) | $90-180 | Inbox Banner, Advertising Benchmarks 2026 |
| Finance list CPM | $70-130 | Inbox Banner, Advertising Benchmarks 2026 |
| Creator/lifestyle list CPM | $25-55 | Inbox Banner, Advertising Benchmarks 2026 |
| Programmatic ad fill rate | 85-98% | Influencers Kit, Newsletter Ad Rates 2026 |
| Readers more receptive to newsletter ads vs pop-ups | 16x | LiveIntent (via Whop, 2026) |
| Readers preferring ad-sponsored free newsletters | 79.6% | What If Group (via Whop, 2026) |
Outlier: direct sponsorships fill only 40-60% of inventory versus 85-98% for programmatic, which is why many publishers now run a hybrid stack (beehiiv, State of Newsletters 2026).
4. Platform Scale: Substack, beehiiv, and Kit
The infrastructure layer consolidated fast. Substack crossed 35 million active subscriptions and a $1.1 billion valuation, while more than 5 million of those subscriptions are paid (Backlinko, Substack Statistics 2026) - roughly double the 2024 figure. Sources diverge on the exact paid count (some report higher figures for Q1 2026), reflecting how quickly the number moves and the lag in official disclosures. beehiiv, the growth-focused rival, reached 255 million unique readers and expanded into podcast hosting at a 0% revenue cut, signaling that the platforms now compete to be the creator’s entire back office rather than just an email tool.
| Metric | Value | Source |
|---|---|---|
| Substack total active subscriptions | 35 million | Backlinko, Substack Statistics 2026 |
| Substack paid subscriptions | 5 million+ | Backlinko, Substack Statistics 2026 |
| Substack writers earning money | 17,000+ | Backlinko, Substack Statistics 2026 |
| Substack valuation (July 2025 Series C) | $1.1 billion | Backlinko, Substack Statistics 2026 |
| beehiiv unique readers reached, 2025 | 255 million+ | beehiiv, State of Newsletters 2026 |
| beehiiv emails sent, 2025 | 28 billion | beehiiv, State of Newsletters 2026 |
| Kit (formerly ConvertKit) creators served | 600,000+ | EmailToolTester, Kit Review 2026 |
| Kit creator earnings processed | $2 billion+ | EmailToolTester, Kit Review 2026 |
Context: Substack’s top 10 authors collectively earn about $40 million a year, and 52 newsletters clear $500,000+ annually (Backlinko, Substack Statistics 2026) - a reminder that platform totals mask a steep power-law distribution.

5. Audience, Demographics, and Reader Behavior
Willingness to pay is rising, and it is disproportionately young. Gen Z adults aged 18-24 are three times more likely than the 55+ cohort to pay for content subscriptions (CivicScience, 2026 Publisher Subscription Landscape), overturning the assumption that older readers are the reliable subscribers. The broader trend is durable: the share of Americans refusing to pay for any publisher content fell from 72% in 2021 to 61% in 2026, and multi-subscription households (two or more paid publications) grew 50% over five years to 24% of adults. Quality - not price - is now the leading factor in subscription decisions, which favors focused, well-edited newsletters over broad content mills.
| Metric | Value | Source |
|---|---|---|
| Gen Z (18-24) likelihood to pay vs 55+ | 3x | CivicScience, 2026 Publisher Subscription Landscape |
| Americans unwilling to pay for content (2026) | 61% | CivicScience, 2026 Publisher Subscription Landscape |
| Americans unwilling to pay for content (2021) | 72% | CivicScience, 2026 Publisher Subscription Landscape |
| Adults with 2+ publisher subscriptions | 24% | CivicScience, 2026 Publisher Subscription Landscape |
| Health & Fitness subscribers under 35 | 61% | CivicScience, 2026 Publisher Subscription Landscape |
| Consumers subscribed to at least one newsletter | 47.3% | What If Group (via Whop, 2026) |
| Gen Z reading email on smartphones | 70%+ | MailPro, Email Marketing for Gen Z 2026 |
| Adults using social/video as main news source | 54% | Reuters Institute, Digital News Report 2026 |
Outlier: the $100-$199 annual spending tier surged 57% to represent 11% of U.S. adults, showing that premium willingness-to-pay is expanding, not just casual signups (CivicScience, 2026).
6. Devices, Deliverability, and AI Adoption
Where and how newsletters get read shapes every design decision. Apple Mail commands 51.52% of email opens and Gmail 26.72% - nearly 90% of the market between them (Litmus, Email Client Market Share, February 2026), and mobile devices account for 55-60%+ of opens. That concentration means Apple’s privacy behavior effectively sets the rules for open-rate measurement industry-wide. On the production side, AI is entering unevenly: 34% of email marketers use AI for copywriting at least occasionally, yet an estimated 80%+ of independent newsletters still run no automation beyond a basic welcome email - a wide gap between early adopters and everyone else.

| Email marketing software market (2026) | $13.72 billion | Mordor Intelligence, Email Marketing Market 2026 |
Context: the automation gap is a monetization gap. Creators repurposing issues into audio, video, or narrated formats reach the 55%+ of audiences who now favor social and video for news (Reuters Institute, Digital News Report 2026). Our text-to-speech statistics cover that audio-first shift in detail; this newsletter data is the creator-side complement to our commerce-focused email marketing statistics.
