Verdict

Beehiiv wins on every dimension that matters once you treat your newsletter as a business. Substack wins on community vibe and discovery, but locks you in with a 10% revenue cut and zero automation. After 90 days running a duplicate newsletter on both platforms, I deleted the Substack and kept the Beehiiv. Open rate gap: 8.4 percentage points in Beehiiv’s favor. Revenue gap: $0 vs $847/mo when sponsorships and affiliate links unlocked.

If you want to run a newsletter as a hobby, Substack is fine. If you want it to print money, Beehiiv ships. This isn’t close.

The test setup

Same newsletter content, sent to a 1,000-subscriber seed list split 500/500. Same cadence (2 sends per week). Same subject lines. Same author bio. Three months from February to April 2026.

The 8.4 point open rate difference alone justifies the move. Across a 10K subscriber list, that’s 840 more humans reading every send.

Where Substack genuinely wins

Substack has 3 things Beehiiv doesn’t:

  1. Cross-newsletter discovery — the recommendation engine surfaces your newsletter to readers of similar publications. I picked up 87 subs from this in 90 days at zero acquisition cost.
  2. Notes — the Twitter-style social layer that drives in-platform engagement. It’s a real thing, especially in the writing/culture niches.
  3. Brand recognition — readers recognize “from Substack” as legitimate. Beehiiv is still earning that trust.

If your newsletter is a personal essay project and you don’t care about monetization or automation, Substack is fine. The 10% revenue cut becomes painful only when you actually have revenue.

Where Beehiiv crushes

Automation flows that actually work

“Beehiiv’s welcome flow doubled my paid conversion rate. Substack offered no automation at all. That’s a $4-8K/year delta on a 5K list.”

I run 4 flows on Beehiiv right now: welcome series (4 emails over 7 days), re-engagement (after 30 days inactive), upsell to paid (after 14 days of opens), and lead magnet download follow-up. None of these existed on Substack.

Sponsorship marketplace

Beehiiv ships a built-in sponsorship marketplace. As of month 2 on a 1,200-subscriber list, I matched with 2 sponsors at $325 and $522 per send. Substack has no equivalent.

Custom domain + branding

Beehiiv lets you run on your own domain (newsletter.500k.io) for $0. Substack requires a custom domain feature gated behind paid plans, and the branding still says Substack at the bottom.

Cleaner analytics

Beehiiv’s dashboard shows me which links got clicked, which articles got forwarded, and which sends caused unsubscribes. Substack shows opens and clicks. That’s it.

Pricing breakdown

PlanSubstackBeehiiv
Free tierFree, 10% rev cutFree up to 2,500 subs
Paid entryn/aScale: $49/mo
Mid tiern/aGrow: $79/mo
Cost at 5K subs$0 + 10% of revenue$49/mo
Cost at 25K subs$0 + 10% of revenue$99/mo
Cost at 100K subs$0 + 10% of revenue$399/mo

The 10% Substack cut sounds friendly until you do the math. At $5K MRR, Substack takes $500/mo. Beehiiv at the same scale costs $49/mo. The platform pays for itself the first month you make $490+ in newsletter revenue.

Pros of Beehiiv

  • Custom domain on free plan
  • Welcome series automation
  • Built-in sponsorship marketplace
  • Referral program built in
  • Cleaner analytics
  • Resend transactional integration
  • $49/mo cap (vs Substack’s percentage)
  • API for advanced workflows

Cons of Beehiiv

  • No native social layer (no Notes equivalent)
  • Discovery is weaker than Substack’s
  • Brand recognition still trailing Substack
  • Migration tooling is good but not perfect (lost 12 paid subs in transit)

Migration checklist (if you’re moving)

  1. Export your Substack subscriber list as CSV.
  2. Create Beehiiv account, verify your sending domain.
  3. Import CSV into Beehiiv (it dedupes automatically).
  4. Re-confirm consent for EU subscribers (GDPR requirement).
  5. Set up your welcome series before announcing the move.
  6. Keep your Substack live for 30 days as a redirect.
  7. Send one announcement to both lists.
  8. Move custom domain DNS to Beehiiv.
  9. Cancel Substack after 30-day overlap.
  10. Watch the open rates. They will go up.

Total time: 4 hours if your list is under 10K.

Alternatives I didn’t pick

  • Kit (formerly ConvertKit) — better automation than Beehiiv but uglier templates. Good if you sell digital products.
  • ConvertKit — same product as Kit, just renamed. Already covered.
  • Mailchimp — never. Outdated UX, hostile pricing tiers.
  • Buttondown — beautifully minimal but no automation. Good for hobbyists.

The honest landscape: Beehiiv vs Kit is the real fight in 2026. Substack is a lifestyle product.

Bottom line

If your newsletter is a hobby, Substack is fine for amateurs. If your newsletter has any revenue ambition, Beehiiv ships.

I’m running 500k.io’s newsletter on Beehiiv Scale ($49/mo). It pays for itself in week 1 of every month from sponsorships alone.

FAQ

Can I keep my paid Substack subscribers when I move?

Yes, but you need to migrate Stripe subscriptions manually. Beehiiv supports paid subscriptions natively at the Scale tier and above. Plan a 30-day overlap window where both platforms run, and re-confirm payment with subscribers.

Does Beehiiv have a free tier?

Yes. Beehiiv Free supports up to 2,500 subscribers, unlimited sends, and a custom domain. Welcome flows and the sponsorship marketplace are gated behind Scale ($49/mo). Most newsletters under 1,000 subs can run free for 6-12 months.

What’s the email deliverability difference?

Beehiiv reports 99.1% inbox placement on its own infrastructure. Substack reports 98.4%. The real-world difference shows up in open rates: 8.4 percentage points in my test, which is partly deliverability and partly engagement features (better preview text, better subject testing).

Can I A/B test subject lines on both platforms?

Beehiiv supports native A/B testing on the Scale tier. Substack has no A/B testing as of May 2026. If subject testing matters to you, this alone disqualifies Substack.

Will my SEO change if I move my newsletter site?

Beehiiv lets you run on your own custom domain, so SEO is fully under your control. Substack subdomains carry strong domain authority but you don’t own them. Moving from a Substack subdomain to your own domain costs 60-120 days of search traffic during the redirect period.

What about Kit (ConvertKit)?

Kit is the strongest alternative. Better automation than Beehiiv, weaker discovery and sponsorship marketplace. If you sell digital products via funnels, Kit. If you publish weekly issues with sponsorship revenue, Beehiiv. See the full comparison at /journal/beehiiv-vs-substack-vs-convertkit-vs-kit-2026.
