Which Newsletter Platform Should You Use? 5 Questions, One Answer (2026)

Disclosure: This page contains affiliate links. If you purchase through these links, we may earn a commission at no extra cost to you. Pricing references were checked on official pages in September 2026.

Comparison tables give you every fact except the decision. This page runs the decision instead: five questions, in order, each with a clear branch. Answer honestly and you'll land on a platform — with the reasoning visible, not vibes.

If you want the long version behind any answer, every question links to the full analysis. This page is the spine; the comparisons are the depth.

Question 1: How will the newsletter make money?

This is the load-bearing question. Everything else adjusts around it.

• Sponsorships / ads → beehiiv. It's the only one of the three with the revenue machinery built in: ad network, Boosts marketplace, sponsor-ready analytics. Agencies that run newsletter growth say the same thing.
• Selling your own products, courses, services → Kit. Commerce, tagging-based segmentation, and launch-grade automations are native. The other two can bolt parts on; Kit is built as the engine.
• Paid subscriptions from readers → Substack for now, with an exit number. Network discovery is real and the fee is $0 until it isn't: Substack keeps 10% of paid revenue, which costs more than Kit's ≈$390/year fee once paid revenue passes ≈$325/month (≈$490/month vs beehiiv). Know your crossover before you commit.
• Nothing yet, maybe ever → Question 2 decides; monetization pressure is zero.

Question 2: How fast is the list growing?

The free-plan caps are time limits, not size limits:

• Slow, organic growth → either free tier works; Kit's runway removes the deadline.
• Fast growth, paid-ads-assisted or referral-driven → beehiiv's growth machinery might justify the earlier paywall; you're paying for the thing accelerating you.
• Unknown → default Kit. A cap you hit in year three is a better problem than one you hit in month ten.

Full math: free plans compared.

Question 3: Do you need a real website for the newsletter?

• Yes, a home page with an archive, SEO, and subscribe forms → beehiiv. Its website builder is the strongest of the three; your newsletter is a publication, not just an email.
• No, email is the product → Kit's landing pages and Substack's minimal site both cover the basics.
• Your writing IS the site → Substack's archive and Notes network do the job with zero setup.

Question 4: What growth tactics will you actually run?

• Referral programs, cross-promotions, paid boosts → beehiiv (all built in; Boosts literally let you pay other newsletters for subscribers).
• SEO and organic search → beehiiv's site or a Kit landing page both index; Substack archives rank inconsistently.
• Social distribution (X, LinkedIn, communities) → platform-agnostic; your content does the work. Our LinkedIn-specific flow covers the native-tool question.
• Pure "write and hope" → any platform; pick by Questions 1-2 and stop optimizing the wrong thing.

Question 5: Are you moving from somewhere?

• From Mailchimp or another legacy tool → CSV import works on all three; if you're a creator selling anything, Kit's import + tagging rebuild is smoothest. The broader "leaving Mailchimp" comparison is on our roadmap.
• From Substack → you keep the list (CSV out), lose the 10% on the other side. Migration guide coming; the fear is mostly undocumented, the mechanics are simple.
• Starting fresh → skip this question.

The five answers, assembled

Count your answers. The platform with the most branches wins; when it's a 2-2-1 split, the tiebreaker is Question 1, because monetization fit is the hardest thing to retrofit.

The most common profile we expect in 2026 — new creator, no revenue yet, moderate growth, social-first distribution, maybe products later — maps to Kit: longest free runway, commerce when needed, no percentage taken when monetization starts. That's our default recommendation, stated plainly.

The exception profile — sponsor-first ambitions, growth-hacking mindset, wants a publication website — maps to beehiiv, and the earlier upgrade is a feature, not a bug.

FAQ

Is this page a quiz? It's the decision logic of a quiz without the form. Five branches, self-administered, with links to the full analysis behind each.

What if my answers conflict? Question 1 wins ties. Revenue model fit is the hardest to change later; caps and design are migration problems, and migration is a solved problem (CSV).

Can I switch platforms later? Yes. Every major platform imports and exports CSV. What you actually pay to move: automations rebuild, archive URLs, re-confirmation friction. Hours, not audience.

Where do the numbers come from? Official pricing pages, checked September 2026, with all arithmetic shown in the linked pages. Platform pricing changes; re-verify before purchasing.
