If you're looking to sponsor newsletters, you've probably encountered both Beehiiv and Substack. They're the two dominant newsletter platforms of 2026 — but they're built on very different philosophies, and those differences matter a lot for advertisers.
This is the comparison no one writes: Beehiiv vs Substack from the advertiser's perspective.
A Quick Platform Overview
Beehiiv launched in 2021 as a growth-focused newsletter platform. Its founding team came from Morning Brew, one of the most successful newsletter businesses ever built. Beehiiv was designed from day one to help creators grow and monetize.
Substack launched in 2017 as a writer-first platform emphasizing paid subscriptions and independent journalism. Its core philosophy is about writer autonomy and reader-supported publishing.
These different origins lead to very different advertiser experiences.
Audience Quality Comparison
Beehiiv Audiences
Beehiiv tends to attract:
- Media and growth-focused creators — people who want to build an audience as a business
- B2B newsletters — marketers, founders, operators, tech workers
- Monetization-focused niches — finance, marketing, SaaS, business
The result: Beehiiv audiences tend to be professionals with purchasing power and high commercial intent.
Beehiiv also has better subscriber quality controls. Its growth tools (referral programs, recommendation networks) attract engaged readers who actively sought out the newsletter.
Substack Audiences
Substack tends to attract:
- Writers and journalists — independent media, opinion, long-form
- Political and culture commentary — niche intellectual interests
- Paid subscribers — readers who are willing to pay for content
Substack audiences are often more intellectually engaged but may have less commercial intent (they're there for the ideas, not the tools).
Verdict: For most B2B or consumer products, Beehiiv audiences convert better. For media, books, events, or cultural products, Substack audiences may be a better match.
Sponsorship Discovery
Finding Newsletters to Sponsor on Beehiiv
Beehiiv doesn't have a native advertiser marketplace — you need a directory. That's where BeeDirectory comes in. We index 700+ Beehiiv newsletters with filters for niche, subscriber count, price range, and language. You can find and contact newsletter operators directly.
Finding Newsletters to Sponsor on Substack
Substack has its own discovery features but they're designed for readers, not advertisers. There's no built-in sponsorship marketplace. Finding Substack newsletters to advertise in requires manual search and outreach.
Several third-party tools have built Substack directories, but the ecosystem is less developed than Beehiiv's.
Verdict: Beehiiv is significantly easier for advertisers to navigate. More directories, more transparent pricing, more growth-minded operators who are used to working with sponsors.
Newsletter Quality and Professionalism
Beehiiv Operators
Because Beehiiv's founders came from Morning Brew, the platform has always attracted operators who think like media companies. Many Beehiiv newsletter operators:
- Have formal media kits ready
- Track and share their analytics openly
- Have experience working with sponsors
- Think about audience growth professionally
Substack Writers
Substack writers are often talented but may be newer to the sponsorship game. Many prioritize editorial independence over commercial opportunities. That's admirable — but it means fewer newsletters are actively seeking advertisers, and the process can be more informal.
Verdict: Beehiiv wins for advertiser-friendliness. You're more likely to get a professional sponsorship experience.
Open Rates and Engagement
Both platforms report strong engagement compared to email marketing averages (which hover around 20–22% open rates). Newsletter-specific averages:
| Platform | Average Open Rate | Average Click Rate | |---|---|---| | Beehiiv | 38–50% | 3–7% | | Substack | 40–55% | 2–5% |
Substack open rates tend to be slightly higher — likely because paid subscribers are more committed. But Beehiiv's click rates are comparable or better, suggesting audiences are more action-oriented.
Verdict: Roughly equal on engagement metrics. Substack has a slight edge on opens; Beehiiv has a slight edge on clicks.
Monetization Philosophy
This is where the platforms diverge most significantly.
Beehiiv's Approach
Beehiiv actively encourages creator monetization through:
- Beehiiv Ad Network — built-in sponsorship marketplace (though limited)
- Boosts — a growth tool where readers can subscribe to multiple newsletters at once
- Creator tools — referral programs, paid recommendations, premium tiers
Beehiiv wants creators to make money, and sponsorships are a core part of that vision.
Substack's Approach
Substack is fundamentally a paid subscription platform. Its revenue model is taking a 10% cut of creator subscriptions. Advertising is tolerated but not celebrated — some Substack writers explicitly refuse advertising on principle.
Verdict: Beehiiv is the better platform for newsletter advertising. It's built into the creator culture.
Price Comparison
Sponsorship prices vary wildly by audience size and niche, but here are rough comparisons:
| Audience Size | Beehiiv Newsletter Cost | Substack Newsletter Cost | |---|---|---| | 1,000–5,000 | $50–$200 | $25–$150 | | 5,000–25,000 | $200–$1,000 | $150–$800 | | 25,000–100,000 | $800–$4,000 | $600–$3,500 | | 100,000+ | $3,000–$15,000 | $2,500–$12,000 |
Pricing is driven by niche, engagement, and audience demographics more than platform. A finance newsletter on either platform will cost more than a lifestyle newsletter with the same subscriber count.
Verdict: Similar pricing. Beehiiv newsletters may command a slight premium due to their growth-focused audiences.
Which Should You Choose?
Choose Beehiiv if:
- Your product targets professionals, entrepreneurs, or business-minded consumers

The honest answer: Start with Beehiiv. The ecosystem is more advertiser-friendly, the audiences have strong commercial intent, and the discovery process is significantly easier.
