Email marketing tools for solopreneurs, compared by job: newsletter, selling or automation. Free-plan limits read on each vendor page, plus the setup to start.
The best email marketing tools for solopreneurs are the simplest ones that send a welcome sequence and a weekly email to a list you own. Start on a free plan, choose by the job you need done, and switch only when a limit stops you, not when a roundup tells you to.
Search this topic and you get lists of 12, 16, even 17 tools, ranked by affiliate commission as often as by fit. This guide does the opposite. You get the three jobs email does for a one-person business, a table of free-plan limits I checked on the vendors' own pages, the mistakes that cost you subscribers, and what to set up first. It is one chapter of the series that starts with Solopreneur Tools: What a One-Person Business Needs.
Email marketing tools for solopreneurs: the three jobs
Before you compare brands, name the job. A solopreneur uses email for one of three things, and each one points to a different kind of tool.
- Publish. A weekly newsletter to people who chose to hear from you. You need a clean editor, a signup form and a fast way to send. Nothing else.
- Sell. Launches, product emails, course or service offers. You need tags or segments, so a buyer does not get the pitch they already bought.
- Automate. A welcome sequence that runs without you. You need triggers and delays. This is the job that most separates tools, because free plans limit it first.
Most solopreneurs need job one on day one, job three in week three, and job two when there is something to sell. That order matters. If you have no list, you do not need segmentation. You need a signup form and a first email.
The book makes the same point about choice: the list of newsletter platforms is ConvertKit, Substack and Beehiiv, and "pick one, doesn't really matter, they all work." The tool is rarely what stops you. The empty list is.
Free email marketing plans compared: what I checked
Pricing pages change monthly, and third-party roundups go stale fast. When I searched for this article, two roundups disagreed about MailerLite's free plan, and another reported that Mailchimp had cut its free tier. So the table below shows only what I read on each vendor's own page on 22 October 2026. Check the page before you commit.
| Tool | Free plan, as read on its pricing page | Automation on free? | Cheapest paid step |
|---|---|---|---|
| MailerLite | Up to 250 subscribers, 2,500 emails a month | Yes: 3 active automations, 5 steps each | Comfort, from $12 a month; the price rises with subscribers |
| beehiiv | Up to 2,500 subscribers | No: automations start on the Lite plan | Lite, $49 a month billed annually ($59 monthly) at the 1,000-subscriber tier |
| Mailchimp | 250 contacts, 500 emails a month (250 a day) | No: automation flows are not on the free plan | Essentials; the page I read showed a promotional price in a local currency, so I do not quote it |
| Kit (ConvertKit) | Page returned an error; I could not read it | Check the page | Check the page |
| Brevo | Page loaded without figures; I could not read it | Check the page | Check the page |
Read the table for its shape, not its numbers. Two free plans cap you at 250 contacts, and the one with the biggest free list (beehiiv) holds back automation. The one that gives you automation (MailerLite) limits it to three. That is the real trade: free plans give you either size or automation, rarely both. Decide which you need first.
Best email marketing tool for a solo founder: choose by situation
Here is how I would decide, using the three jobs above and nothing else.
- You are starting a newsletter and have under 250 people. Any free plan works. Pick the editor you enjoy writing in, because you will use it every week. The cost of the wrong choice is a one-hour list export.
- You want a welcome sequence from day one. Filter on automation first, list size second. A plan that lets you build the three emails below is worth more than a plan with room for 2,000 people you do not have yet.
- You plan to grow the list through a newsletter itself. Those are growth features. You only need them once the list is growing.
- You already run a CRM. Then your email tool should talk to it, or be part of it. A second list in a second place is the failure we describe in CRM for Solopreneurs: How to Choose One That Fits.
Notice what is not on the list: "the one with the most templates," "the one with the biggest integration count," or "the one an influencer uses." A beautiful template does not get replies. Plain text does, and it is available on every plan.
What to check before you pick an email tool
Features rarely decide whether an email tool is right. Constraints do. Check these five before you import a single address.
- What happens at your next size? Prices rise with subscriber count on every plan above. Find the price at 2x and 5x your list. You are not buying today's price.
- Which limit hits first? Emails per month, active automations, steps per automation. The free MailerLite plan, for example, stops at three active automations. A welcome sequence uses one.
- Can you export your list? If you cannot leave with every address and its tags, you are renting your audience. Test the export in week one.
- Can you verify your sending domain? Sending from an unverified domain puts your emails in spam. The fix is three DNS records, SPF, DKIM and DMARC. Our post on Transactional vs Marketing Email explains why, and it is boring, one-time and non-negotiable.
- Does unsubscribe work in one click? Honour it immediately. Providers expect it, and so do your readers. This is deliverability hygiene, not legal advice, so ask a local professional if you sell into regulated markets.
Email automation for solopreneurs: the only three emails you need
Automation is where solopreneurs overbuild. A thirty-email funnel is written once and left to go stale. Three emails, written in about an hour, do the handover from stranger to subscriber and then run for every new person forever.
| When | Its job | |
|---|---|---|
| 1. Delivery | Day 0, immediately | Confirm the signup, deliver what you promised, say what you send and when |
| 2. Your story | Day 3 | The truth about how you got here, not a pitch, with a soft invitation to reply |
| 3. One question | Day 7 | Ask what they are stuck on; replies feed content and sales conversations |
Our full templates are in Email Nurture Sequence: The Only 3 Emails You Need. The note there is that about one in ten subscribers answers the day-seven question, and the answers shape what you write next. That reply rate comes from my own experience, and it is not a benchmark for your list.
The two things that kill a sequence are pitching too early and writing for everyone. If email two is an ad and email three is a discount code, you have taught people your emails are promotions.
Marketing email is not receipt email
The mistake that quietly hurts most solo businesses is pushing everything through one pipe. A newsletter tool sends to many people on a schedule you chose. A receipt, a password reset or a failed-payment notice goes to one person, right now. Different trigger, different audience, different rules.
Mix them and the receipts inherit the reputation of your promotions: one sloppy blast and the password resets start missing inboxes. If you take payments, send receipts from your payment tool or a transactional service and keep the newsletter tool for the newsletter. The full split is in Transactional vs Marketing Email: Get the Split Right.
Where email sits in your stack, and a note on FIKR
Email is the one audience you own. No algorithm sits between you and the list, which is why we say to build it before you launch: see Build an Audience Before You Launch (Not After). Start the newsletter now and the product has people waiting when it ships.
I build FIKR, so weigh this accordingly. FIKR Hub is the module that holds contacts, forms, email campaigns and sequences together, so the form that captures a lead, the record that stores them and the sequence that follows up are the same system. That removes the sync problem. It also ties you to one vendor, and a specialist email tool may beat it at one narrow job. If you are validating an idea, a free plan and a spreadsheet are enough. The honest rule is to decide once and write the decision down.
If you are still deciding whether to leave your job to build this, start with the Corporate Suffocation Index, then come back and set up your first list.
Frequently asked questions
What is the best email marketing tool for a solopreneur?
The one that covers your current job at the lowest cost: a plain editor for a newsletter, a few automations for a welcome sequence, or segments for selling. For most solopreneurs that is a free or low-cost plan from MailerLite, beehiiv or Kit. I could not read Kit's pricing page, so verify it yourself.
Is there a free email marketing tool that includes automation?
Yes. When I read MailerLite's pricing page, its free plan listed automations, limited to 3 active ones with 5 steps each, alongside a 250-subscriber and 2,500-email cap. Mailchimp's and beehiiv's free plans listed no automation. Plans change, so check before you build on one.
How many emails should a new solopreneur send?
One automated sequence of three emails over the first week, then one email a week at a fixed day and time. Consistency matters more than volume. A fixed schedule teaches readers when to expect you.
Do I need a separate tool for receipts and invoices?
Usually your payment tool sends them. Keep these transactional messages apart from your newsletter so promotion problems never block a receipt. We cover the payment side in Invoicing and Payments for Solopreneurs.
