Best email tool for a creator growing a free newsletter to thousands of readers

Best default: beehiiv if you’re building a newsletter as a creator business. Its free plan supports up to 2,500 subscribers with unlimited sends, and it includes newsletter publishing, a website, analytics, and growth tools. You’ll need a paid plan to keep growing past that free limit and unlock more features. (beehiiv.com)

Choose Kit instead if your newsletter supports a broader creator business—like courses, products, or services—and you expect to grow past a few thousand readers soon. Its free plan currently covers up to 10,000 subscribers, but visual automations require a paid plan. (help.kit.com)

Quick rule of thumb:

• beehiiv: newsletter-first, with built-in growth and monetization tools.
• Kit: creator-first, especially if you’ll use email to sell products or build automated sequences.
• Substack: simplest if you mainly want to write and tap into its network; it takes 10% of paid subscription revenue if you monetize there. (support.substack.com)

For a free newsletter aiming for several thousand readers, I’d start with beehiiv if the 2,500 free cap suits your near-term growth; pick Kit if avoiding an early platform switch is the priority.

Short answer: For a free newsletter heading into the thousands, beehiiv is the strongest all-round pick, with MailerLite the best budget option and Kit the best if you're a creator who wants automation. Verify current pricing before you commit, since the roundups I found disagree on some numbers.

Top picks

• beehiiv: beehiiv is free (up to 2,500 subscribers) and makes it easy to design, send, and scale your newsletter. Its growth tools are a draw for a free newsletter. One source lists referral programs (subscribers who refer friends), Boosts (earn money by recommending other newsletters), A/B testing on subject lines, paid subscriptions with 0% fee. The catch is cost at scale: starts at $49/mo for 10K subscribers.
• MailerLite: Good value. One roundup says free for up to 250 subscribers and 2,500 emails/month, paid plans from $12/month, while another puts its free tier at up to 1,000 subscribers, advanced design tools, automation, and robust analytics. Pricing sources conflict here, so check the live page.
• Kit (formerly ConvertKit): Built for creators. Newsletter: $0/month, up to 10,000 subscribers, unlimited newsletter sending and forms. The free tier is limited on automation, and paid plans are pricier. One source says it's expensive at $39/month for 1,000 subs vs. MailerLite at $12.
• Substack: Simplest option, with built-in discovery. It has no subscriber limit on its free plan, but takes 10% of paid subscription revenue.
• Ghost: Best if you want your own website and memberships with no revenue cut. Its pricing is slightly more expensive than beehiiv or MailerLite, but it's because you're also getting a full CMS.
• Buttondown: Cheap and writing-focused. It is free for the first 100 subscribers, bills only for active subscribers, which can get pricey if your list grows fast.

How to choose

• Plan to charge readers later? Choose beehiiv or Ghost (0% platform cut, Stripe fees apply). Avoid Substack if you want to keep the 10%.
• Want the most automation and digital-product sales? Choose Kit.
• Watching costs closely? Choose MailerLite, or Buttondown if the newsletter is mostly text.
• Want discovery from other readers? Substack and beehiiv both have recommendation networks.

Since you're growing a free list, the main cost driver is subscriber count. Compare the paid tier at your expected size, such as 5,000 or 10,000 subscribers, rather than the entry price.

The "best" tool depends on your primary goal: whether you want to treat your newsletter as a standalone media business, a marketing channel for digital products, or a simple writing platform.

In 2026, the three industry-leading options for creators are Beehiiv, Kit (formerly ConvertKit), and Substack.

Quick Summary: Which One to Choose?

Detailed Breakdown

1. Beehiiv: Best for Growth-Focused Newsletters

If your goal is to reach thousands of readers by treating your newsletter like a business (similar to Morning Brew), Beehiiv is currently the top choice.

• Why it wins: It is "growth-first." It features a powerful recommendation network (where you can exchange subscribers with other newsletters), a referral program that incentivizes readers to share your content, and an integrated ad network.
• Free Plan: Up to 2,500 subscribers, making it very generous for those just starting.
• Best for: Creators who want to scale quickly and monetize through ads or subscriptions.

2. Kit (formerly ConvertKit): Best for Selling Products

If you are an educator, coach, or creator who sells digital products (courses, ebooks, templates), Kit is the superior choice.

• Why it wins: It is built for marketing funnels. It offers advanced email automation, subscriber tagging, and deep segmentation based on what your readers purchase or click.
• Free Plan: Extremely generous, covering up to 10,000 subscribers.
• Best for: Creators whose primary revenue comes from selling their own products rather than newsletter sponsorships or subscriptions.

3. Substack: Best for Simplicity & Community

Substack is the easiest way to start if you want to focus entirely on writing and don't want to worry about technical setup.

• Why it wins: It is a "social" newsletter platform. It provides a simple writing experience and a built-in community/discovery ecosystem (via "Notes"), which can help you gain your first few hundred readers without much effort.
• Free Plan: Unlimited subscribers for free, but they take a 10% fee if you eventually turn on paid subscriptions.
• Best for: Writers who prioritize simplicity and want to build a community within an existing network.

Final Recommendation

• Choose Beehiiv if you want to become a full-time newsletter publisher with aggressive growth tactics.
• Choose Kit if your newsletter is a tool to sell your own digital products and you need advanced email sequences.
• Choose Substack if you want to get started in 5 minutes and prefer a low-maintenance, "set it and forget it" writing experience.

Best all-around: beehiiv if you want a newsletter-first platform built for growth. Its free plan includes unlimited sends for up to 2,500 subscribers, plus core newsletter and website tools. ¹

Best if you expect to pass 2,500 readers soon: Kit. Its free plan supports up to 10,000 subscribers, with unlimited broadcasts, forms, and landing pages—so you can grow without an immediate platform bill. ⁵⁶

My quick rule:

• Choose beehiiv for a dedicated publication and growth-focused newsletter features.
• Choose Kit for a larger free subscriber allowance and creator-oriented tools.
• Choose Substack if you mainly want a simple writing-and-publishing experience; it’s free to publish, but takes a cut when you monetize with paid subscriptions. ¹⁰

For a free newsletter aiming at “thousands,” I’d start with Kit if minimizing cost is the priority, or beehiiv if its publishing and growth approach fits your plans better. Check current plan details before committing, since pricing and features can change.
