The claim
Launch an AI-written newsletter, grow fast, sell sponsorships and paid subs.
Steady interest in beehiiv/Substack growth and 'AI newsletter' playbooks, but no breakout news moment in 2026.
How we checked
This is an evidence check, not a hands-on test. We reviewed platform rules and policies, published earnings data, regulator warnings and reporting: 2 sources, listed below.
Costs
- Start-up cost
- £0–£40/month

- high
What the evidence shows
Newsletters do make money: beehiiv says about 30% of its creators earned revenue in Q1 2026. But the median free-to-paid conversion is about 0.6%, and sponsors pay for engaged readers you have to build slowly. AI can speed up drafting, but generic AI summaries are interchangeable, so the people who succeed add real curation, expertise or a clear voice.
Realistic earnings: Commonly £0–£100 a month by month 12; first sponsorships usually need a few thousand engaged subscribers.
Limitations
Earnings ranges are typical outcomes for a beginner, drawn from the sources; some people do far better or worse. Platform rules change often, so check the latest policy before you start.
Works for some, not most.
