Which Email Tool Has the Biggest Free Plan in 2026? (10,000 vs 250 Subscribers)

10,000 subscribers vs 250: what $0 actually buys you, and the catch attached to each plan

Disclosure: This post contains affiliate links. If you sign up through them, I may earn a commission at no extra cost to you. I only recommend tools I believe are genuinely useful, and I say plainly when a competitor beats the tool I earn from. See my Affiliate Disclosure.

But “biggest” and “best for you” are not the same question, and the gap between them is where beginners lose months. Below is every free plan compared on the numbers, plus the catch attached to each one — including the catch on the winner.

All figures checked on the official pricing pages and help documentation on 21 July 2026. Free plans change often; verify before you commit.

Free plans ranked by subscriber limit

Tool	Free subscribers	Email sends	Branding on your emails?	Can you sell?
Kit	10,000	Unlimited	No	Yes (fees apply)
beehiiv	2,500	Unlimited	Yes	No — paid tiers only
Systeme.io	2,000	Unlimited	No	Yes, 0% fees
GetResponse	500	2,500/month	Yes	No
MailerLite	250	2,500/month	Yes	No

The spread is enormous — Kit’s free plan is forty times larger than MailerLite’s. If you had assumed all free tiers were roughly equivalent, that table is the single most useful thing in this post.

1. Kit — 10,000 subscribers (the winner on numbers)

Kit, formerly ConvertKit, offers a Newsletter plan at $0 that carries up to 10,000 active, unique subscribers. That is not a trial. It includes:

• Unlimited email sends
• Unlimited forms and landing pages
• Tagging and segmentation
• A/B testing and conditional content
• Selling digital products and subscriptions
• 1 basic visual automation with 1 email sequence

Worth knowing: the pricing page contradicts itself

If you go to Kit’s pricing page, the free plan card reads “For 1,000 email subscribers” while the comparison table further down the same page says “Up to 10,000”. That is not a typo you should guess about, so I checked Kit’s own help documentation, which states plainly: “Up to 10,000 active, unique subscribers.”

The 10,000 figure is correct. The card appears to reflect the default position of the pricing slider rather than the plan ceiling. Mentioning it because if you looked at that page and concluded the free plan was 1,000, you undersold it by 90%.

The catch

Kit is explicit about how it funds this: “For us to keep this plan free for up to 10,000 subscribers with all these amazing features, there will be one Kit-managed Recommendation slot enabled and any Paid Recommendation earnings generated from that slot will go to Kit.”

In plain terms: Kit places a recommendation in your newsletter, and keeps the money it earns. You are paying with a slice of your audience’s attention instead of cash. Whether that is a good trade is your call — but it is a real cost, and it is the reason the free plan can be this generous.

The other limit: 1 basic automation with 1 sequence. Fine for a welcome email. Not enough for a funnel with branching logic.

Best for: writers and creators whose main output is a newsletter, who want the most room to grow without paying.

2. beehiiv — 2,500 subscribers

beehiiv’s free Launch plan covers up to 2,500 subscribers with unlimited email sends, and includes things most free tiers do not: a website, a podcast module, custom domains, the recommendation network and an AI website builder.

The catch

beehiiv branding appears on your emails, and removing it requires the Max plan — not the mid tier, the top one. Also excluded from free: email automations, digital products, surveys and polls, the ad network and community features.

So beehiiv free is a strong publishing plan and a weak selling plan. You can grow an audience beautifully; you cannot monetise it directly until you pay.

Best for: newsletter-first creators who care about growth, discovery and design more than about selling a product this quarter.

3. Systeme.io — 2,000 contacts (but it does more than email)

Systeme.io’s free plan holds 2,000 contacts with unlimited emails. On subscriber count alone it ranks third. But comparing it purely on subscriber count misses what it is:

• 3 sales funnels (15 funnel steps total)
• 1 online course with unlimited students
• 1 blog
• 1 custom domain
• 1 affiliate program
• 0% transaction fees on what you sell
• No branding on your emails

Kit and beehiiv are email tools. Systeme.io is an all-in-one platform — funnels, checkout, course hosting and email in one place. On the free tier you can build a landing page, capture emails, deliver a lead magnet, sell a course and run an affiliate program without paying anything or connecting a second tool.

The catch — and it is a sharp one

The free plan allows 1 automation rule, 1 workflow, 1 tag and 1 email campaign. Delivering a single lead magnet typically consumes one automation rule and one tag. Your entire allowance, spent on the first thing you build.

Unlimited broadcast newsletters still work. But a second automated sequence, or any real segmentation, needs the $17/month Startup plan. Be clear-eyed about that before you build your whole business on the free tier.

Best for: beginners who want to sell something, not just send newsletters. Start on the free plan here — no card, never expires.

4. GetResponse — 500 contacts

GetResponse’s free tier gives you 500 contacts and 2,500 emails per month. Do the arithmetic before you rely on it: 500 contacts × one weekly newsletter = 2,000 emails. One extra broadcast and you are at the ceiling.

The catch

Three of them. A GetResponse badge on every message. Landing pages capped at 1,000 unique visits per month across the whole account — cross it and your pages go offline, precisely when traffic finally arrives. And automation limited to basic autoresponders.

There is also a structural quirk: you begin with a 14-day trial of the premium features, and the restricted free tier is what you land on afterwards. You spend two weeks learning tools you then lose.

Best for: people who intend to pay soon and want to test the full suite first. As a permanent free home, it is the weakest option here apart from MailerLite.

5. MailerLite — 250 subscribers

MailerLite’s free plan is 250 subscribers and 2,500 emails per month, with the MailerLite logo on your emails until you upgrade. The cheapest paid plan starts at $12/month billed annually.

MailerLite has a strong reputation for a clean interface and good deliverability, and that reputation is deserved. But 250 subscribers is a starter allowance, not a growth allowance — it is the smallest free tier of the five, by a distance.

Best for: people who value simplicity above all and expect to upgrade quickly.

So which should you actually pick?

Subscriber count is the wrong first question. The right one is what are you going to do with the list?

• Write a newsletter and grow it as large as possible before paying → Kit. 10,000 free subscribers is unmatched, and the Recommendation slot is a fair trade for it.
• Sell a course, ebook or digital product → Systeme.io. It is the only free plan here where you can build the funnel, host the product, take the payment at 0% fees and email the buyer, without a second tool.
• Build a newsletter brand with a website and podcast → beehiiv, if you can live with its branding on your emails.
• Test a full marketing suite before committing budget → GetResponse.
• You want the simplest possible tool and will pay soon → MailerLite.

I earn a commission on Systeme.io and not on Kit, so let me be direct about it: if all you want is a newsletter, Kit’s free plan beats Systeme.io’s and you should use Kit. Systeme.io wins when selling is part of the plan. Recommending the wrong one to you would earn me a few dollars once and cost you months.

Frequently asked questions

Which free email plan has the most subscribers in 2026?

Kit, at up to 10,000 active unique subscribers with unlimited sends — four times beehiiv’s 2,500 and forty times MailerLite’s 250.

Are these free plans permanent or trials?

Kit, beehiiv, Systeme.io and MailerLite are permanent free tiers. GetResponse’s free tier is what remains after a 14-day premium trial ends.

Which free plans let me sell products?

Systeme.io (0% transaction fees) and Kit (fees apply per transaction). beehiiv, GetResponse and MailerLite require a paid plan to sell.

Which free plans put branding on my emails?

beehiiv, GetResponse and MailerLite. Kit and Systeme.io do not — though Kit places a managed recommendation slot in your newsletter instead.

Can I switch tools later?

Your contact list exports as CSV from all five. What does not move is your automations, funnels and landing pages — those get rebuilt by hand. That rebuild is the real switching cost, and it is why this choice matters more at 100 subscribers than it feels like it should.

What is the catch with free plans generally?

Every free tier is funded somehow: branding on your emails, a capped send limit, a recommendation slot, or a feature wall placed exactly where a growing business hits it. None of these are scams — but knowing which cost you are paying lets you pick the one you mind least.

The bottom line

Kit has the biggest free plan in 2026 at 10,000 subscribers, and if you are building a newsletter it is the obvious starting point. Systeme.io has the most capable free plan at 2,000 contacts, because it is the only one where a beginner can go from landing page to paid customer without spending anything.

Pick based on what you are building, not on which number is largest. Then stop researching and send your first email this week — the tool matters far less than the list, and the list only exists once you start.
