If you have ~41 paid subscribers at $10/month, Beehiiv is already cheaper than Substack — in absolute dollars, not percentages. At 1,000 paid subscribers at $10/month, the gap is $12,324 per year. The math is not close. If you’re monetization-focused and already have an audience, Beehiiv wins. If you’re starting from zero and need the platform to help you grow, Substack’s Notes network is a genuine growth engine and Beehiiv has no equivalent.

Who this is for

Creators considering a paid newsletter who are deciding where to build — or who are on Substack and wondering whether to migrate. If you’re a free-only newsletter operator with no monetization plans, the fee difference is irrelevant and Substack’s zero-friction setup is hard to argue against.

What we tested

Pricing data from both platforms’ live pages (retrieved June 2026). Break-even math is our own, verified against independent secondary sources. Deliverability data from the Twilio/SendGrid case study (Beehiiv infrastructure, published 2025) and EmailToolTester’s updated May 2025 review.

The fee structure

Substack takes 10% of every dollar a paid subscriber spends. Add Stripe’s 2.9% processing fee and the 0.7% recurring billing surcharge (introduced July 2024), and your effective platform take is ~13.6%. There’s no monthly fee — you pay only when you earn.

Beehiiv flips the model. You pay a flat subscription ($43/month on the Scale plan, billed annually at $516/yr; $96/month on Max, billed annually at $1,152/yr), and Beehiiv takes 0% of your subscription revenue. Only Stripe’s 2.9% applies.

That trade-off has a clear crossover point.

The break-even math

At what monthly subscription revenue does Beehiiv’s flat fee beat Substack’s percentage cut?

Beehiiv Scale costs $516/year (about $43/month, billed annually). Your revenue after Stripe but before fees on each platform:

Beehiiv: Revenue × 0.971 − $43
Substack: Revenue × 0.864

Set them equal: 0.971 × R − 43 = 0.864 × R → R = $402/month

In practice:

At $5/month per subscriber: break-even is ~81 paid subscribers
At $10/month per subscriber: break-even is ~41 paid subscribers

Once you’re past that threshold, every additional dollar retained compounds in Beehiiv’s favor.

Annual retained revenue comparison

Paid subs	Price/mo	Annual revenue	Substack nets/yr	Beehiiv Scale nets/yr	Beehiiv advantage
100	$5	$6,000	$5,184	$5,310	+$126
500	$5	$30,000	$25,920	$28,614	+$2,694
1,000	$5	$60,000	$51,840	$57,744	+$5,904
100	$10	$12,000	$10,368	$11,136	+$768
500	$10	$60,000	$51,840	$57,744	+$5,904
1,000	$10	$120,000	$103,680	$116,004	+$12,324
5,000	$10	$600,000	$518,400	$581,448 (Max)	+$63,048

Beehiiv rows use Scale ($516/yr billed annually, ~$43/mo) except the 5,000-subscriber row, which uses Max ($1,152/yr billed annually, ~$96/mo). All figures use Stripe 2.9% only.

This is before factoring in Beehiiv’s additional revenue streams — the Ad Network and Boosts — which have no Substack equivalent.

Email deliverability

Beehiiv runs on Twilio SendGrid infrastructure. After implementing SendGrid’s Engagement Quality Score (SEQ), Beehiiv documented a 52% year-over-year increase in deliverability rate and a 50% reduction in spam complaint rate in their low-performing sender pool. Those numbers come from a verified Twilio case study, not Beehiiv’s own marketing. The case study records 4.35 billion emails processed in total across the platform.

EmailToolTester rates Beehiiv 3.5/5 on deliverability features (updated May 2025), noting that Kit has a slight edge through FBL data access — a fairly narrow technical distinction most creators won’t notice.

Substack has mature infrastructure and most analysts consider both platforms comparable for legitimate senders. The meaningful gap is analytics: Beehiiv surfaces open rates, deliverability stats, and bounce data to creators. Substack doesn’t expose that level of data.

Verdict: Beehiiv has a measurable infrastructure edge and better creator-facing analytics. For a typical legitimate newsletter, the difference is small. For anyone with a mixed-quality list or high send volume, Beehiiv’s proactive IP pool management is worth paying attention to.

Growth tools

This is where the platforms genuinely diverge.

Beehiiv is built for multi-stream monetization:

Boosts: A pay-per-subscriber cross-promotion network. Newsletters pay to be recommended in other newsletters’ confirmation flows. Beehiiv has paid out $5M total to creators through Boosts; many publications report 10–20% net new subscriber growth attributable to this channel.
Ad Network: Set a CPM rate, approve ad placements, earn revenue from non-subscription readers — a monetization channel Substack doesn’t offer.
Referral Program: Built-in reader-refers-reader loop.
SEO control: Full custom URLs, meta descriptions, OG tags. Content is indexed by Google. Substack’s SEO capabilities remain limited by comparison.

Substack is built for organic discovery:

Notes: The standout feature. In-app discovery through Notes has made Substack a genuine growth engine for many early-stage publications — creators regularly report hundreds of new subscribers from single posts surfaced through the feed (Digiday, 2024).
Chat: Turns newsletter posts into community threads. Creators report it changes the reader relationship meaningfully.
Live Video: Co-host sessions with up to two others; tiered access for free vs. paid subscribers.
Email Automations: Rolling out to all creators in 2026 after being gated to top-tier creators in 2025.

Verdict: Beehiiv wins for revenue diversification once you have an audience. Substack wins for initial audience growth. The question is which problem you’re actually solving.

Customization and ownership

Custom domain: Free on Beehiiv’s Scale and Max plans. Substack charges a one-time $50 fee per publication.

Data portability: Both platforms export subscriber lists as CSV. The meaningful difference is paid subscriptions. On Beehiiv, paid subscription data exports fully. On Substack, payment relationships don’t transfer — every paid subscriber must actively re-subscribe on a new platform. Independent data suggests 10–30% churn during paid subscription migrations. For a list of 600 paid subscribers at $8/month, that’s $5,760–$17,280 in at-risk annual revenue if you ever want to leave.

API: Beehiiv offers a public API on paid plans. Substack has no public API.

Verdict: Beehiiv is meaningfully better on portability and integrations. Substack’s paid subscription migration friction is a real cost that compounds the longer you stay.

2026 feature delta

Beehiiv shipped a large batch of new functionality in its Winter 2025 release (announced November 2025, live early 2026):

Feature	Status
Digital products (guides, templates, memberships) — 0% fee	Live
AI website builder	Live
Podcast hosting with newsletter + podcast unified brand	Live
Link in bio (newsletter + site + podcast + products)	Live
Dynamic content (personalized by location, tier, interests)	Live
Enhanced automations with Discord/Slack integrations	Live
Real-time analytics	Live
Beehiiv MCP (operate via Claude, ChatGPT, Gemini)	Live

Substack’s 2025–2026 updates:

Feature	Status
Email automations for all creators	Rolling out 2026
Notes algorithm redesign (surfaces unfollowed creators)	Live
Visual/video Notes	Live
Live video (two co-hosts)	Live
Gift subscriptions	Live

The automation gap is the clearest signal: Beehiiv has had multi-step automations for years. Substack is only now rolling this out to all creators in 2026. Beehiiv’s Winter Release moved the platform toward a full media business tool (podcasts, digital products, AI site builder). Substack’s updates were incremental and focused on its discovery and community layer.

Creator case studies

Kyle Poyar — Growth Unhinged migrated from Substack to Beehiiv in January 2026 after nearly five years on Substack. He described it as a difficult decision. A growth practitioner making a deliberate switch after five years is a meaningful data point — this isn’t someone who left out of frustration with a bad experience; it’s a calculated ROI decision.

Bibin Wilson — DevOpsCube (19,000+ subscribers, technical newsletter) assessed both platforms in April 2026 and concluded Beehiiv suits creators prioritizing SEO, multi-stream revenue, and data control. His specific framing: “with AI and declining search traffic, creators need platforms offering multiple revenue streams.” He recommended Substack only for “pure writing and community building.”

The counterpoint: Digiday documented creators moving to Substack from Beehiiv specifically for Notes, Chat, and co-livestreaming — and reporting real subscriber growth from it. Individual creators cite hundreds to thousands of new subscribers from single Notes posts. Substack’s network effects are real.

The pattern: Creators migrating to Beehiiv are solving for revenue and control. Creators migrating to Substack are solving for community and discoverability. Neither direction is irrational — the platforms optimize for genuinely different things.

Verdict

Pick Beehiiv if you have an existing audience (or know how to grow one yourself) and want to maximize take-home money. The break-even is ~41–81 paid subscribers — not a large number. After that, every dollar you earn compounds the advantage. Beehiiv’s 2025–2026 feature expansion also means you’re building on a platform that’s moving fast toward a full media business tool, not merely a newsletter host.

Pick Substack if you’re starting from zero and need the platform to help you find your first subscribers. Notes is a genuine growth engine. The community features (Chat, Live Video) also create retention dynamics that Beehiiv’s toolset doesn’t match. Accept that you’ll pay Substack 10% for this distribution advantage, and revisit the math when you cross ~100 paid subscribers.

Don’t migrate existing paid subscribers lightly. Substack’s migration friction is real. If you’re on Substack with 500+ paid subscribers, model the churn risk before assuming you’ll net more by switching. For new newsletters, or those with mostly free subscribers, the decision is cleaner.

Caveats

Beehiiv is an affiliate partner. The verdict above reflects the research, not the commission — if Substack were clearly better for this audience, that’s what we’d say. Break-even math uses annual billing for Beehiiv and Substack’s current fee structure as of June 2026; both platforms have changed pricing before and may again. Substack’s custom domain $50 fee and the 0.7% recurring billing surcharge are recent additions (July 2024) — check both platforms’ current pricing before deciding.
