What are some free tools for creating a newsletter?

You already know email works. The numbers are almost absurd: industry research puts email marketing ROI at 3,500% — $36 back for every dollar spent. No social platform, ad channel, or SEO campaign touches that consistently. So the newsletter sits on your to-do list, week after week, quietly judging you.

Here's the catch: you're already drowning in software. A scheduling app, a review tool, a CRM trial you never finished setting up, six browser tabs of dashboards with passwords you keep resetting. The last thing a busy owner wants is one more platform to learn — which is exactly why free newsletter tools are so tempting. Substack, beehiiv, Kit, MailerLite, Mailchimp, Brevo: they cost nothing to start, and they all look simple enough on the signup page.

And the free tiers are genuinely usable. Comparisons of free newsletter platforms show Substack allows unlimited subscribers, Kit covers up to 10,000, and beehiiv handles 2,500 with unlimited sends. Brevo even allows up to 100,000 contacts, capped at 300 emails a day. On paper, you could run a real newsletter for $0.

The tricky part, as one reviewer puts it, isn't finding a free plan — it's figuring out which one actually fits your situation. The limits are wildly different, and the fine print bites later:

• Caps hit fast — MailerLite and Mailchimp free plans stop at just 250 subscribers, and Mailchimp reportedly charges for contacts even after they unsubscribe or go inactive.
• Free plans stamp the platform's branding on every email until you pay.
• Automation is thin — Substack has none at all, no A/B testing, and basic analytics.
• Costs climb as your list grows; beehiiv's paid tier starts at $43/month.

There's also the time math. Free is only free if your time is. Someone still has to pick topics, write the thing, test subject lines, remember to send it, and figure out why open rates stalled — survey data shows creators who use AI in production reclaim 1–3 hours a week, and 64% of newsletter professionals expect fully AI-generated newsletters by 2030. The tool may be free, but the Tuesday night you spend wrestling it is not.

That's the real question this article answers: which free plan fits, where each one breaks, and when it makes sense to stop duct-taping another subscription into your stack and let something like AI Business Sites handle the whole loop — signup, curation, subject lines, sending, and tracking — instead. Let's look at the tools first.

Every free newsletter plan looks generous on the landing page and stingy in the fine print. The real question isn't "is it free?" — it's "what am I actually getting, and when does it stop being free?"

Substack is the only truly unlimited free option: no subscriber caps, no send limits, and built-in monetization. The catch is a 10% cut of paid subscription revenue, plus no automation, no A/B testing, and basic analytics. It suits writers building an audience first and selling later — one Reddit user noted it replaced a $350/month WordPress-plus-Mailchimp setup entirely.

Kit (formerly ConvertKit) offers 10,000 free subscribers with unlimited sends and lets you sell digital products with a transaction fee. That's the most generous "real ESP" free tier on the market, ideal for creators who want automation-ready infrastructure. beehiiv gives 2,500 subscribers and unlimited sends, but no monetization on the free plan — it's built for growth-focused publishers willing to upgrade (paid starts at $43/month).

The smaller tiers are where expectations should be managed:

• MailerLite — 250 subscribers, 2,500 emails/month (limits were recently reduced, per EmailToolTester's comparison); best for ease of use on tiny lists
• Mailchimp — 250 subscribers, 500 emails/month, and it charges for contacts even after they unsubscribe or go inactive, per G2 user feedback
• Brevo — 100,000 contacts but capped at 300 emails/day; fits transactional-heavy senders, not newsletter-first businesses
• EmailOctopus — 2,500 subscribers, 10,000 emails/month; a solid budget pick
• Sender — 2,500 subscribers, 15,000 emails/month; generous send volume for small lists

GetResponse (500 subscribers, unlimited sends) and Buttondown (free for your first 100 subscribers) round out the field for testing-the-waters use cases.

Here's the honest summary: with email marketing returning $36 for every dollar spent, a newsletter is worth doing properly — and most free plans are built to get you started, not to run the whole job. Every one of these tools means learning another dashboard, writing your own subject lines, and remembering to hit send.

That's the gap AI Business Sites was built to close. Instead of another tool to manage, our platform runs a four-agent AI newsletter workflow — a curator, subject-line writer, composer, and spam validator — with A/B subject testing and best-time-to-send analysis built in. The newsletter gets written, validated, and sent as part of a system that also handles your site, CRM, and follow-up. Free is only free if your time is.

"Free" is the most expensive word in email marketing when you read the fine print. The limits on free newsletter plans don't announce themselves — they show up months in, right as your list starts working.

The most common trap is the subscriber cap. Free tiers range from 250 subscribers on MailerLite and Mailchimp to 2,500 on beehiiv and EmailOctopus, with only Substack offering truly unlimited subscribers. A local business adding even a handful of signups a week blows past most of these caps within a year — and that's exactly when the platform expects you to upgrade.

Then there's the branding. Most free plans stamp the platform's logo on every email and signup form, and removing it requires a paid plan. Your newsletter becomes a walking advertisement for someone else's software.

Automation is the third hidden cost. Substack — the only truly unlimited option — has no automation, no A/B testing, and no integrations at all. Meanwhile, the data shows what you're missing: subject lines under 20 characters earn a 37.6% open rate versus 28.68% for longer ones, and AI early adopters reclaim 1–3 hours every week on newsletter production.

And the pricing doesn't stay friendly as you grow. One G2 user reviewing Mailchimp noted that costs "rise quickly as my subscriber list grows, especially since it charges for contacts even after they've unsubscribed or become inactive." You can end up paying monthly for people who will never see another email from you.

Before committing to any free plan, check:

• The subscriber cap and what the paid tier costs when you hit it
• Whether platform branding appears on your emails — and what removing it costs
• What automation actually exists, not just what's promised
• Whether unsubscribed contacts still count against your bill

This is the core of the "free is only free if your time is" problem. Every free tool is another platform to learn, configure, and babysit — another login, another template system, another analytics dashboard to check. For a business owner already running Jobber or a scheduling tool, the newsletter becomes the seventh subscription in a duct-taped stack. And with email marketing returning roughly $36 for every dollar spent, the stakes of doing it consistently are too high to leave it half-managed.

That's the gap AI Business Sites built its newsletter system to close: signup forms on your own site, a four-agent AI workflow handling curation, subject lines, composition, and spam checks, plus A/B subject testing and send-time analysis — part of one managed platform instead of another tab to maintain. The tool is only free until you tally what your hours are worth.

The numbers tell an interesting story: 28% of creators already use AI for brainstorming and 25% for content creation, according to industry trend data. And those who adopt AI early reclaim 1–3 hours every week. The question is no longer whether AI belongs in your newsletter workflow — it's who runs it.

Free tools like Substack, MailerLite, and Mailchimp give you the basics, but the AI work stays on your shoulders. You brainstorm the topics, hunt down the links, write the subject lines, and hope you haven't tripped a spam filter. With 64% of newsletter professionals expecting newsletters to be fully AI-generated by 2030, doing all of that manually is a strategy with an expiration date.

This is where the difference between a tool and a system shows up. At AI Business Sites, the newsletter isn't a separate subscription you learn and manage — it's part of the same platform as your website, CRM, and lead follow-up. A four-agent AI workflow handles the production line:

• A curator agent gathers and organizes content worth sending
• A subject-line writer drafts options — important, since subject lines under 20 characters earn a 37.6% open rate versus 28.68% for longer ones
• A composer agent assembles the actual newsletter
• A spam validator checks the message before it ever goes out

Then the system keeps improving the results. A/B subject testing shows you which headlines actually get opened, open and click tracking reveals what your readers care about, and best-time-to-send analysis finds the window when your audience is most likely to engage — research shows timing matters, with midday sends earning open rates above 42%.

Contrast that with the free-tool path. You'd pick a platform, learn its interface, configure your templates, and remember to log in and send. Meanwhile, the free plans come with trade-offs: subscriber caps, platform branding on your emails, and limited automation. As one analysis of newsletter platforms puts it, the tool stack you choose often matters more than the model you start with — fragmented tools turn every change into a migration project.

The stakes justify getting this right. Email marketing returns an estimated $36 for every dollar spent, but that return only materializes when the newsletter actually goes out consistently and lands well. A free tool that sits unused because you're busy running your business earns exactly nothing.

Free is only free if your time is. A done-for-you system doesn't hand you software to learn — it runs the workflow for you, inside the same place your leads, customers, and content already live. That's the difference between having a newsletter tool and having a newsletter that actually happens.

Here's the honest test: is your newsletter the product itself, or the pipeline to something bigger? As one industry analysis puts it, "the right model depends on whether your newsletter is the product or the pipeline to something bigger" — and that question should drive your tool choice more than any feature list.

If you're testing the waters, start free. Just match the tool to your situation:

• Writing to build an audience — Substack is the only truly free option with unlimited subscribers and sends, though it takes a 10% cut of paid subscriptions and offers no automation or A/B testing (TechnologyAdvice).
• Planning to grow fast — beehiiv's free plan covers 2,500 subscribers with unlimited sends, but monetization requires upgrading (EmailToolTester).
• Selling digital products — Kit (formerly ConvertKit) allows monetization on the free tier, up to 10,000 subscribers (platform comparisons).
• Large contact list, small budget — Brevo's free plan supports 100,000 contacts with a 300-email daily cap (free plan research).

But if the newsletter is a pipeline — a way to turn readers into customers for your actual business — a different math applies. Email marketing returns roughly $36 for every dollar spent, according to ROI research. That kind of return only materializes when the newsletter actually goes out, consistently, week after week.

That's where free tools quietly fail business owners. Every free plan means you learn the software, write the content, configure the sends, and troubleshoot the deliverability — on top of running the business. And the costs of staying free aren't zero: research on free plans shows most carry platform branding on every email, and Mailchimp user reviews note it charges for contacts even after they've unsubscribed.

The trend data points one direction, too: 64% of newsletter professionals expect newsletters to be largely AI-generated by 2030, and AI early adopters already reclaim 1–3 hours weekly. A managed platform like AI Business Sites runs the newsletter for you — signup form, content workflow, subject-line testing, open and click tracking — as part of a system that also handles your website, follow-up, and leads. Month-to-month, no long-term contract.
