Free email tools come in two kinds: the ones that genuinely run a small business for £0, and the ones that hand you 500 contacts and a countdown to the upgrade screen. Pick the wrong one and you migrate your whole list six months in, which nobody enjoys.

I went through the current free plans for the tools solopreneurs actually shortlist. Here is what each one gives you in 2026, where the wall sits, and which to pick for your situation.

What "free" should mean for a one-person business

Three things matter when you have no team and no budget:

1. Enough contacts to grow into, so you are not migrating the moment things work.
2. Enough sends to actually email those contacts, not a daily cap that throttles a launch.
3. Automation, so a welcome sequence can sell while you sleep.

Most free plans give you one or two of these. A few give all three.

The free plans, ranked for solopreneurs

Systeme.io — best free all-in-one

The free plan covers 2,000 contacts with unlimited email sends, and throws in sales funnels, a blog, an online course and your own affiliate programme. For a solopreneur that is the whole front end of a business in one login, not just an inbox tool.

Honest limitation: the email templates are basic, and you get a single automation rule on free, so one welcome sequence rather than ten branching ones. For most people starting out, one good sequence is all you run anyway.

Best for: anyone who needs to capture subscribers on a landing page and sell to them, not just send newsletters. Full breakdown in our Systeme.io free plan review.

Kit (formerly ConvertKit) — most generous contact allowance

Kit's free plan gives you up to 10,000 subscribers with unlimited sends. On raw numbers that beats everything else here.

Honest limitation: the free automation is thin, built around single sequences and broadcasts, and the platform is shaped for creators selling their own products. If pure email to a large list is the entire job, it is hard to beat.

MailerLite — best email designer on free

500 contacts and 12,000 emails a month, with a genuinely good drag-and-drop builder and automation included on the free tier.

Honest limitation: 500 contacts fills faster than you expect, and new accounts go through an approval step before sending.

Brevo — best if your list is large but you email rarely

Brevo's free plan allows a huge contact list, up to 100,000, but caps you at 300 emails a day, roughly 9,000 a month.

Honest limitation: that daily cap makes a real campaign crawl, and free emails carry Brevo branding. Good for storing a big list cheaply, awkward for an active sender.

Mailchimp — the famous name, now the thinnest free tier

500 contacts and about 1,000 sends a month.

Honest limitation: it is the priciest to upgrade once you grow, and the free tier gives you the least room of any tool here. Familiar, but you will outgrow it quickly.

GetResponse also runs a free tier at 500 contacts with its AI campaign features, worth a look if those features appeal.

Quick comparison

Which one to pick

• You want one tool for email, landing pages and selling: Systeme.io.
• You only want to send newsletters to a large list: Kit.
• You care most about how the emails look: MailerLite.
• You have a big list but email occasionally: Brevo.
• You can skip it: Mailchimp, since you will outgrow the free tier fast and the upgrade is dear.

The honest bottom line

For most solopreneurs starting from zero, the email list is only half the job. You also need a page to capture subscribers and somewhere to sell to them. Getting email, funnels, a blog and a checkout free in one place beats stitching three tools together and hoping they talk to each other. That is why Systeme.io is the pick here.

The fair caveat: if you only ever plan to send newsletters to a large audience and nothing else, Kit's 10,000-subscriber free plan is the better single-purpose choice. Match the tool to the job, not the logo.

Once you have picked one, the next step is the sequence that does the selling. Our 7 AI workflows guide covers the welcome sequence as workflow number two.
