beehiiv vs Substack 2026: Pricing, Features, SEO & API Tools

My newsletter open rate used to be 65%. It’s 39% now.

Nothing broke. I’ll explain why that number fell, because it’s the most misunderstood metric in this entire comparison, and both platforms are quietly complicit in the confusion.

This is what actually separates them — and one difference that decided it outright for me.

✅ Bottom Line Up Front

The Pricing Models Are Not Comparable

People compare beehiiv pricing against Substack pricing and get it wrong, because they aren’t the same kind of price.

Substack has no plans. Publishing is free at any list size. The moment you turn on paid subscriptions, Substack takes 10% of every transaction. Stripe adds 2.9% + $0.30 per transaction, plus a 0.7% recurring billing fee.

On a $10 monthly subscription that’s about $1.66 gone — roughly 16.6%. On a $100 annual subscription it’s $13.90, about 13.9%.

There’s also a one-time $50 custom domain fee, and minimums of $5/month or $50/year on any paid tier.

beehiiv charges a subscription that scales with your active subscriber count and takes 0% of your revenue.

Subscribers	Scale	Max
1,000	$43	$96
2,500	$61	$131
5,000	$78	$149
10,000	$96	$193
25,000	$149	$254
50,000	$219	$334
100,000	$290	$404

Those are annual-billed, shown monthly. Month-to-month costs more. Above 100,000 subscribers — counted across every publication in your workspace — you’re forced onto Enterprise.

Run the crossover yourself. At 10,000 subscribers, beehiiv Scale costs $96 a month, $1,152 a year. To pay Substack that much you’d need about $8,300 in annual subscription revenue at their ~13.9% annual rate.

If you’re earning more than that, beehiiv is cheaper. If you’re earning less — or nothing — Substack is.

The Free Tiers

Substack’s free tier is more generous, unambiguously. No subscriber cap, no feature gating, and you can monetise on it. That is the model.

The API Asymmetry That Decided It

This is the section that ended the comparison for me, and almost nobody writes about it.

Every week, my newsletter is drafted, assembled and pushed to beehiiv without me touching the dashboard. Claude does the research and the draft, hits the beehiiv API, creates the post, schedules the send. I review before it goes.

That workflow is possible on exactly one of these two platforms.

beehiiv has a full public write API. The Create Post endpoint accepts title, body content or blocks, subtitle, scheduled time, recipients, email settings, SEO settings, content tags and custom fields. Set status to draft and it saves. Set it to confirmed and it publishes. Pass scheduled_at and it schedules.

It requires the Max plan, which is the real cost of this workflow — $96/month annual-billed at 1,000 subscribers.

They also ship an official MCP server, available to every user including free accounts, with read-only access on free and full content management on paid. There are setup guides for Claude, Claude Code, Cursor and Codex.

One limitation worth knowing: the MCP can create and manage, but publishing must happen in the app or through the REST API. For fully unattended sending you need the API, not the MCP.

If you already run a beehiiv automation, check it today. On 6 August 2026 beehiiv changed the Create Post default — posts created without an explicit status now save as draft instead of publishing. Sensible change, and it will silently stop any automation that relied on the old behaviour.

Substack’s API cannot publish. Their Developer API terms, effective 8 January 2026, scope it to “publicly available creator information” — names, social URLs, subscriber counts, profile summaries. Permitted uses are display and discovery. Prohibited uses include competing with Substack’s core features.

There’s no official Zapier app, no official MCP server, and no documented endpoint that creates, schedules or sends a post. Unofficial reverse-engineered wrappers exist and sit awkwardly against those terms.

If automated publishing matters to you, this is not a close comparison. It’s the difference between a workflow that exists and one that doesn’t.

Monetisation: Ads, Subscriptions, Recommendations

This is where beehiiv has spent its engineering budget, and it shows.

beehiiv Ad Network. Available on Scale and above. You need an active send history and a Stripe Express account. beehiiv vets advertisers, surfaces offers in a dashboard, you accept the ones you want, and they handle tracking and reporting. Payouts land on the 20th of each month.

Two models: CPM, paid per thousand unique opens, and CPC, paid per verified click after bot and bounce filtering.

On earnings, be careful what you believe. beehiiv’s documentation uses “$5 CPM” and “$2 CPC” as worked examples, not as a rate card. There is no published RPM. Anyone quoting you typical beehiiv ad earnings is guessing.

What is published: beehiiv’s cumulative Ad Network creator earnings counter reads about $37.8 million, and their July 2026 release says Ad Network newsletters collectively earn over $1 million monthly.

Finding sponsors manually is a job. Having offers appear in a dashboard, already matched to my audience, is the difference between running a newsletter business and running a sales team.

Recommendations, formerly Boosts. As of July 2026, Boosts were renamed paid recommendations and merged with free recommendations. The model is CPA — you pay or earn per verified new subscriber, with geolocation targeting, auto-accept and auto-pause. Email Boosts and Direct Links are retired for new campaigns.

beehiiv reports 30,000+ active publishers in the recommendation network, and that participants grew 2.75x faster than non-participants.

Paid subscriptions: beehiiv takes 0%. Only Stripe’s cut applies. Requires Scale or above.

Substack’s side. Paid subscriptions with founding-member tiers, trials, coupons and gifts. Pledges let readers commit payment details before you monetise, converting when you switch paid on — a genuinely good feature beehiiv has no equivalent for.

And Substack now has ads. They launched a native sponsorship programme on 15 June 2026 with brands including Yahoo Scout, Whatnot, Granola, Balenciaga, T-Mobile, Polymarket and Uber. Substack handles matchmaking and logistics; creators pick partners and keep editorial control.

The eligibility bar is at least 100 paid subscribers. And Substack’s revenue cut on sponsorships has not been disclosed.

That last point matters. beehiiv publishes its ad model. Substack hasn’t published its sponsorship terms.

Deliverability, and What Neither Tells You

beehiiv publishes its sending stack. Substack publishes nothing.

beehiiv runs on Twilio SendGrid. Their case study documents 4.35 billion emails processed, a 1,037% year-on-year volume increase, and a 52% improvement in deliverability rate. They use SendGrid’s Engagement Quality Score to segment shared IP pools, which pushed open rates up 3% in the worst-performing pool.

Platform-wide for 2025: 98.90% delivery rate, 1.48% bounce rate, 0.02% spam complaint rate. Self-reported, but published and specific.

Dedicated IPs are Enterprise-only.

On Substack, I could find no first-party documentation of sending infrastructure, throughput limits, IP management or deliverability at all. No ESP named, no numbers, no dedicated IP option at any level.

That absence is itself the finding. If deliverability is a business risk for you, one platform gives you something to audit and the other gives you nothing.

Why My Open Rate “Fell” From 65% to 39%

Here’s the honest version, and it’s more useful than the number.

My open rate was 65% at its peak. It averages 39% now. Same content, same team, a bigger list.

Three things are happening, and only one of them is about my newsletter.

1. First, list size. A 3,000-person list of people who chose you recently will always outperform a 40,000-person list accumulated over years. That’s mathematics, not decline.
2. Second, and this is the big one: Apple Mail Privacy Protection. Since iOS 15, Apple pre-fetches remote content — including the tracking pixel — through its proxy servers at delivery, whether or not a human ever opens the email. Every one of those registers as an open.

Litmus reports that over half of all email opens now happen on MPP-affected devices.

That number reframes every open rate you have ever seen.

So a reported open rate is roughly real opens from non-Apple recipients, plus 100% of Apple recipients with MPP on. It has been inflated for years.

3. Third, here’s the tell. In beehiiv’s own platform data, open rate rose from 37.67% in 2024 to 41.24% in 2025, while click-through rate fell from 4.74% to 3.23%.

Opens up 3.6 points. Clicks down 1.5 points. Same audience, same year.

That divergence is very hard to explain as real engagement improvement. It’s what progressive MPP adoption looks like.

Two practical takeaways. Use click-through rate as your real engagement number — around 3.2% platform-wide is the benchmark to beat. And never compare a beehiiv open rate to a Substack open rate, because Substack changed how it calculates opens to include Substack app inbox receipt and in-app views. Different numerator, different denominator, on top of MPP. Any head-to-head open-rate comparison between these two is methodologically meaningless.

Analytics

Closer than the marketing on either side suggests.

beehiiv’s 3D Analytics splits into a Posts Report and a Subscribers Report. The genuinely useful part is acquisition-source attribution combined with subsequent performance of those cohorts — you can filter by where a subscriber came from and see how that cohort opens and clicks afterwards. That turns ad spend into a measurable cohort ROI question. Scale plan and above.

Substack reports total, paid and free subscriber counts, gross annualised revenue, per-post views across web, email and app, open and delivery rates, clicks and CTR, plus free and paid conversions attributed per post.

It also has paid net growth, cohort analysis and churn dashboards — better native revenue reporting than beehiiv, and better than most people assume.

The split: beehiiv wins on acquisition-cohort ROI and link-level detail. Substack wins on subscription revenue and churn reporting. If your business is paid subscriptions, Substack’s numbers are more directly useful. If your business is growth and sponsorship, beehiiv’s are.

SEO and Owning Your Website

beehiiv is a website platform with a newsletter attached. Substack is a newsletter with a themeable front page.

beehiiv gives you custom domains on every plan including free, plus editable meta titles and descriptions with a live preview. You also get per-page indexability control covering search engines and AI crawlers, automatic XML sitemaps, Open Graph and Twitter card settings, editable slugs and documented Search Console setup.

Cloudflare AI Crawl Control is available on Max and Enterprise with custom domains.

Substack gives you a custom domain for a one-time $50, an SEO title, meta description, editable slug and social preview image. Posts are indexable and Substack handles it for you.

Also worth noting: Substack’s own SEO guide is dated February 2023. In a category where Google has changed substantially, that tells you how much priority it gets.

For SEO-led growth, this isn’t close. beehiiv gives you materially more control.

The Lock-In Nobody Mentions

Both platforms tell you that you own your audience. Both are telling the truth about your list and misleading by omission about the thing that actually matters.

You can export your list from both. beehiiv gives you a quick export or a full export with custom fields and statistics, delivered as CSV with a 24-hour download link. Substack gives you a full CSV including engagement data — though notably you cannot export subscriber names, only email addresses.

You can export your posts from both. beehiiv as CSV. Substack as CSV and HTML.

Neither lets you take your live paid subscriptions.

Substack’s own migration guide is explicit about this in the other direction. Moving to Substack means uploading a CSV of emails and renewal dates, then comping those readers while they re-enter payment details and resubscribe from scratch. You create a new Stripe account on Substack.

The same applies leaving either platform. Your email list is portable, and so is your content.

Your recurring revenue is not. Switching means asking every paying subscriber to re-subscribe, and you will lose some.

That’s partly a Stripe and PCI constraint rather than pure platform policy. The practical effect is identical either way.

So pick carefully at the point you turn on paid subscriptions. That’s the moment the switching cost appears, and neither pricing page mentions it.

FAQs

The Question That Actually Decides It

Forget the newsletter platform feature lists. Answer one question.

Is your newsletter a publication, or is it a system?

If it’s a publication — you write it, you send it, readers pay you — Substack’s distribution and zero-upfront model are hard to argue with.

If it’s a system — automated, integrated, feeding a wider business, measured on cohort ROI — you need an API and a website you control. That’s beehiiv, and the gap isn’t small.

I’ve run both. Mine is a system.
