Best free newsletter platforms in 2026: what each free tier actually lets you do
"Free newsletter platform" hides a wide range of meanings. Some free tiers cap subscriber count but include every feature (Beehiiv). Some let you grow to 10,000 subscribers but lock automation behind a paywall (Kit). Some are free forever with no platform fee but take 10% of any paid subscription revenue (Substack). Picking the wrong "free" can cost you more than picking the right paid plan. Here's what each platform's free tier actually includes — and where the gotchas are.
The highest-quality free tier in 2026 is Beehiiv Launch — 2,500 subscribers with full publishing features, custom domain support, API access, and the ability to charge for paid subscriptions at a 0% take rate. Kit's free Newsletter plan technically supports 10,000 subscribers but limits you to a single basic automation and removes A/B testing. Substack is free at any subscriber count but takes 10% of every paid subscription dollar, making it the expensive option above ~$4,000/year in paid revenue. MailerLite caps free at 1,000 subscribers but unlocks paid plans cleanly. The "best" free tier depends entirely on whether you intend to monetize and at what scale.
TL;DR
- Beehiiv Launch — best free tier for most new newsletter operators (2,500 subs, full features, 0% take on paid subs)
- Substack — best if you want unlimited free subs and don't care about platform fees yet (10% take when you monetize)
- Kit Newsletter (free) — best if you'll stay in the 2,500–10,000 sub range and don't need automations
- MailerLite Free — best if you'll cap below 1,000 subs but want a real path to a paid plan
- Brevo Free — best for low-frequency senders (300 emails/day cap, not subscriber cap)

What "free" actually costs you
Three hidden costs to watch for:
- Substack's 10% take rate. Free to publish, but as soon as you turn on paid subscriptions, you're paying 10% of every dollar forever. At $5,000/yr in paid sub revenue, that's $500 — more than a year of Beehiiv Scale ($516).
- Kit's free-tier feature gating. 10,000 subs sounds generous until you realize you can't run a single automation, can't A/B test, and have Kit branding on every email. Most operators outgrow this within 3 months and need to upgrade — at which point the post-October-2025 pricing applies.
- Custom domain gates. Beehiiv includes custom domains on free. Substack charges $50 one-time AND removes you from their recommendation network. Most others gate custom domains to paid plans entirely.
Where this comparison gets nuanced
- Ghost self-hosting is "free" only if your time is free. Setup is 4–8 hours and ongoing maintenance is real. For most creators, Ghost(Pro) hosted ($9/mo) is the practical option.
- Substack network value is hard to quantify. Their recommendation engine and Notes feed genuinely drive new subscribers in ways no other platform replicates. Picking against Substack purely on the 10% take ignores this.
- Brevo's "300 emails/day" math. That's 300 individual emails, not 300 broadcast sends. If you have 100 subscribers and send 3x/week, you'll hit the cap. If you have 50 subscribers and send weekly, you'll never come close.

Methodology & sources
Free-tier feature lists, subscriber caps, and send limits were sourced from each vendor's pricing page on 2026-05-29 and cross-verified against the vendor's help docs. Where free-tier limits were unclear on pricing pages, we deferred to the vendor's signup flow (which displays the actual cap at account creation).
Letterbench earns affiliate commission on signups via Beehiiv's Partner Program and AWeber's Advocates program. We have applications pending with MailerLite (direct), Sparkloop (direct), and Canva (Impact). We are not affiliated with Substack, Ghost, Mailchimp, Brevo, GetResponse, or Kit. Beehiiv ranks #1 because its free tier objectively includes more features at its cap than competitors — not because of the affiliate relationship.
