CPA-based newsletter subscriber acquisition (Boosts)
Pay other newsletters a fixed cost per acquired subscriber to turn newsletter growth into a predictable, performance-marketing-style channel.
Why this can grow a startup
Traditional paid acquisition channels like Meta and Google ads face rising CPMs and declining trust. Newsletter Boosts leverage the existing trust relationship between a creator and their audience, resulting in higher-quality subscribers who are already in a reading mindset. Because the cost model is per-acquisition rather than per-impression, founders can set a predictable CAC and scale spend proportionally to results. The channel also sidesteps ad fatigue since the promotion appears as a natural recommendation within content the reader already chose to open.
Company example
Beehiiv Boosts — founders set a CPA bid and other newsletter creators promote the paying newsletter to their audience, turning subscriber acquisition into a measurable paid channel similar to Google Ads but with higher trust and intent signals.

When to use it
Use this when Communities is relevant to 0-100, 100-1K and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
Founder checklist
- Read stormy.ai and identify what is directly supported.
- Choose one channel context: Communities.
- Define the test around one observable customer behavior.
- Set an owner, evidence window, and stop condition before launch.
