Mailchimp vs Brevo vs Kit: Best Email Marketing Software in 2026

This email marketing software comparison has one clear answer for solopreneurs in 2026: Kit. It holds up to 10,000 subscribers and sends unlimited emails at $0, while Mailchimp stops you at 250 contacts and Brevo stops you at 300 emails a day.

Brevo and Mailchimp both bill you for the privilege of growing a list. Kit mostly doesn't. The catches are real, though: Kit's free plan won't run visual automations, Brevo is the cheapest of the three if you only send a weekly digest, and Mailchimp still has the best templates and ecommerce reporting of the lot. I've paid for Mailchimp and Kit on my own lists and used Brevo for client sends, and every number below is re-checked against the vendors' pricing pages in October 2026.

Quick verdict: see it at a glance

Here's the whole article in one table. Criteria are ordered by what actually decides the bill for a small list.

Criterion (checked Oct 2026)	Mailchimp	Brevo	Kit	Winner
Free plan	250 contacts, 500 sends/mo	Unlimited contacts, 300 emails/day	10,000 subs, unlimited sends	Kit
Cost at 10,000 subs, weekly sends	~$110/mo (Essentials)	~$39/mo (Starter)	$0, or ~$119+/mo with automations	Kit
Pricing model	Per contact stored	Per email sent	Per subscriber, free to 10K	Brevo
Cheapest real automation	Standard tier, from $20/mo	Standard, from $18/mo	Creator, from ~$39/mo	Brevo
Templates & design	Best of the three	Functional, plain	Text-first, limited	Mailchimp
Deliverability signal	Claims 99%+ delivery	91/100 EmailDeliverabilityReport, May 2026	Strong shared pool; pro reporting on Pro only	Tie
Best for	Stores and ecommerce shops	Big stored lists, cheap sends	Creators selling digital products	Kit overall

Verdict: pick Kit if you're a creator or solopreneur under 10,000 subscribers. Pick Brevo if you store a lot of contacts and email them rarely, or you need automation on a tight budget. Pick Mailchimp only if polished templates and ecommerce reporting matter more than the monthly bill.

Which should you choose?

• Choose Kit if you want unlimited sends to up to 10,000 subscribers at $0, you sell digital products, and you can live without full visual automations until you're ready to pay.
• Choose Brevo if your list is big but your sending is light, you want SMS and a CRM in the same dashboard, or you need proper automation for under $20 a month.
• Choose Mailchimp if you run an online store, need the strongest template library and revenue reporting, and would rather pay more than wrestle with a clunkier editor.

Most comparisons get this wrong: they score 40 features nobody uses at 2,000 subscribers, then bury the price table. At this list size the bill and the send limits decide everything. The three sections below cover, in order: what each tool charges, what it quietly refuses to do, and what it costs you at every step from zero to 10,000.

Is Mailchimp still worth paying for in 2026?

For most solo senders, no. Mailchimp cut its free plan down to 250 contacts and 500 emails a month effective February 17, 2026, and stripped automation out of it at the same time — a change documented in Retainful's March 2026 pricing audit, which traced the free tier from 2,000 contacts in 2022 to 500 in 2023 to 250 today. That's a demo account, not a plan. You outgrow it in about six weeks.

Paid tiers start at $13/month (Essentials) and $20/month (Standard) for up to 500 contacts on Mailchimp's own pricing page. Then the contact bands do their work: roughly $20–30 at 1,000, $45 at 2,500, $75 at 5,000, and somewhere around $110 at 10,000 as of mid-2026 — Mailchimp moves these bands more often than any rival, so treat every figure here as approximate. Sends are capped at 10× your contact count on Essentials, 12× on Standard. Cross the cap and you buy overages or your send halts.

What you get for the money is real. The template library is the best-looking of the three, the drag-and-drop editor never fights you, and Standard unlocks up to 200 automation flows, behavioral targeting, and generative AI features — Intuit Assist is included at no extra cost as of 2026. If AI drafting is part of your week, our roundup of AI tools for productivity shows where that actually saves time versus where it's a demo.

I watched my own Essentials bill go from $13 to about $75 in under two years without adding a single feature. Nothing broke. The list just grew. That's the Mailchimp experience in one sentence: the product works, and the invoice scales faster than the results do.

What makes Brevo the cheapest option?

Brevo bills by emails sent, not contacts stored — the single biggest structural difference in this comparison. You can keep a million contacts in the account and pay nothing until you mail them. The free plan allows unlimited contacts and 300 emails per day, roughly 9,000 a month if you spread it out.

Starter starts at $9/month for 5,000 emails, and Standard at $18/month for the same 5,000 — Standard is where marketing automation, A/B testing, advanced reporting and removal of the Brevo footer all unlock. Volume tiers climb gradually: around $29 at 20,000 sends, $39 at 40,000 and $69 at 100,000 on Starter (Email Vendor Selection, May 2026 — approximate, and yearly billing takes 10% off). Transactional email via API and SMTP is included on every plan, which quietly saves you a separate service if you send receipts or password resets.

The catch people miss: on the free plan, removing the Brevo logo from your emails is a paid add-on at about $10.80/month — more than double the Starter plan it sits on (SMTPedia, August 2026). And the daily cap cuts both ways. A weekly broadcast to 10,000 subscribers is 10,000 emails in one day, which is 34 days of sending on the free plan. Unlimited storage is only free if you never mail the whole list at once.

Brevo also bundles a CRM, SMS, WhatsApp and landing pages, and it's EU-based, which simplifies GDPR paperwork for European sellers. For a solopreneur running side hustles that make money across several small lists, that storage-for-free model is genuinely hard to beat.

What do you actually get with Kit's free plan?

More than any competitor, and that's why Kit wins this comparison. The free Newsletter plan covers up to 10,000 subscribers with unlimited broadcasts, unlimited forms and landing pages, tagging and segmentation, A/B testing on broadcasts, and the ability to sell digital products and paid subscriptions straight from your list — confirmed in Kit's own help center and announced in Kit's Newsletter plan announcement. No credit card, no time limit.

What it doesn't cover: visual automations, full multi-step sequences, API access and third-party integrations. Those move to the paid Creator plan at $39/month for up to 1,000 subscribers on monthly billing, or roughly two months free on annual billing (Kit's Creator vs Pro guide). At 5,000 subscribers Creator runs about $79/month, and at 10,000 somewhere around $119–139 as of mid-2026 — approximate, since Kit repriced in late 2025 and third-party listings still disagree. A basic welcome sequence is included free; the full funnel builder is not.

Two smaller costs hide in the fine print. Sales made through Kit's own checkout carry a platform fee reported at about 0.6% on top of Stripe's processing fee, and free accounts get lower priority in Kit's Recommendations network — paid plans are featured more often, which is exactly where a lot of free-plan growth comes from.

Honest counterpoint: Kit's editor is the least pretty of the three, and its form and landing page builders are stiff. I stopped fighting them and embed simple forms on my own pages instead. For text-based newsletters nobody notices. For a visual brand, Mailchimp is the better canvas.

What does it cost from 0 to 10,000 subscribers?

This is the table I wanted when I started. Mailchimp figures are monthly, Essentials tier, approximate. Brevo assumes one broadcast a week — four sends a month per subscriber — because Brevo bills on volume, not headcount. Kit is free through the whole column unless you need automations.

Subscribers	Mailchimp (Essentials)	Brevo (Starter, weekly sends)	Kit	Cheapest
0 (free tier)	$0 — 250 contacts, 500 sends/mo	$0 — unlimited contacts, 300/day	$0 — 10,000 subs, unlimited sends	Kit & Brevo
500	~$13/mo	$0	$0	Kit / Brevo
1,000	~$20/mo	$0	$0 (Creator ~$39/mo for automations)	Kit
2,500	~$45/mo	~$17/mo (10K sends)	$0	Kit
5,000	~$75/mo	~$29/mo (20K sends)	$0 (Creator ~$79/mo)	Kit
10,000	~$110/mo	~$39/mo (40K sends)	$0 (Creator ~$119–139/mo)	Kit

Read it as a story, not a grid. At 1,000 subscribers Mailchimp already costs more than Brevo's paid entry and Kit's free tier. At 5,000 it costs roughly what Brevo and Kit cost together. At 10,000 you're paying about $1,320 a year for something a rival gives away — and every one of those prices carries the same warning: all three companies repriced at least once in the past 18 months.

A free plan you outgrow in six weeks isn't a free plan. It's a delayed invoice with better marketing.

Will your emails reach the inbox?

Deliverability is where vendor claims get creative, so here's the honest split. Mailchimp advertises a 99%+ delivery rate on its deliverability page — delivery means the receiving server accepted the message, not that it landed in the Primary tab. Brevo scored 91/100 in independent testing by EmailDeliverabilityReport, cited as of May 2026, and it auto-configures DKIM and DMARC when you connect your domain. Kit runs a well-regarded shared IP pool among creator senders, but its advanced deliverability reporting sits on the $79/month Pro plan.

Meanwhile, Mailercloud's 2026 head-to-head scored Mailchimp and Brevo a tie on inbox placement, with the useful caveat that results vary more by sender than by tool. That matches what I see: the tool matters far less than three habits — authenticate your domain before you import anyone, warm a new sending domain over one to two weeks instead of dumping 5,000 contacts on it in a day, and prune unengaged subscribers every quarter.

My test is boring and it works: seed a new campaign to my own addresses at Gmail, Outlook and Yahoo first. If it hits all three inboxes, send. If it doesn't, fix the list before the real send, not after the complaint rate moves.

How do you switch tools without losing subscribers?

Nobody should stay on the wrong tool over migration fear. The process is one afternoon plus a week of overlap — and if you're fitting this around client work, pair it with one block from our remote work productivity tips, because scattered evenings are how migrations die.

1. Export everything first. Download your subscriber CSV with tags, signup dates and custom fields before you cancel anything.
2. Authenticate your domain. Add SPF, DKIM and DMARC records in the new tool and confirm they pass before importing.
3. Import and map fields. Match every tag and custom field during upload — repairing a flat import later takes days.
4. Warm the new sender. Send to your most engaged 10% first, then the rest across a week, watching bounce and complaint rates.
5. Overlap for 30 days. Keep the old account alive for bounces and replies for one month, then cancel it.

Honest cons for all three

Mailchimp cons

• Free plan is 250 contacts and 500 sends with no automation — effectively unusable past the trial stage.
• Contact-band billing punishes growth: the same account costs about 8× more at 10,000 than at 500.
• Send caps (10× contacts on Essentials) trigger overages or silence right when a campaign matters.
• Advanced automation, custom-coded templates and serious segmentation sit on the higher tiers only.

Brevo cons

• 300 emails per day on the free plan makes any full-list broadcast from a 10,000-subscriber list impossible.
• Removing the Brevo logo costs about $10.80/month on Starter — more than the plan itself.
• Automation, A/B testing and landing pages don't unlock until Standard at $18/month plus volume.
• The editor and reporting are functional but plain; you trade Mailchimp's polish for the price.

Kit cons

• The free plan blocks visual automations, full sequences, API access and third-party integrations.
• Paid tiers climb fast after 1,000 subscribers — roughly $79 at 5,000 and $119–139 at 10,000 as of mid-2026.
• Design tools are the weakest here: limited templates, a stiff form and landing page builder.
• Kit's checkout takes a reported ~0.6% platform fee on sales, and free accounts get lessRecommendation exposure.

Verdict: which one wins in 2026?

Kit is the best email marketing software in 2026 for solopreneurs, creators and remote workers who sell digital products and run a list. Ten thousand subscribers and unlimited sends at $0 is not a close call when the nearest alternative charges about $110 a month for the same audience. Kit's free plan has real limits — no full automations, no integrations — but a broadcaster with a welcome sequence and a product to sell can run on it for years.

Brevo takes second place honestly. If your shape is "huge list, occasional sends," or you need automation under $20, it beats Kit outright. Mailchimp comes third for this audience: a great product with the least generous pricing model in the group, saved only for people who need its template quality and store reporting.

One thing the price tables can't do is grow the list itself. Whichever tool you pick, the asset is the audience — and the fastest path from an empty account to a list that pays is a system you actually follow every week. That's exactly what our product Email List Engine is for: a 30-day plan to grow and monetize your email list, built for creators who'd rather send than fiddle with settings. Pick Kit, plug the plan in, and the tool choice starts to matter a lot less.

Frequently asked questions

Which is cheapest: Mailchimp vs Brevo vs Kit at 10,000 subscribers?

Kit is cheapest — $0 if you can live without visual automations, or roughly $119–139/month for Creator as of mid-2026. Brevo lands near $39/month for weekly sends to that list, and Mailchimp's Essentials tier runs about $110/month. At every size between 1,000 and 10,000, Kit's free plan undercuts both.

Is Mailchimp's free plan usable in 2026?

No. Since February 17, 2026 it allows 250 contacts, 500 emails a month, and no automation. Treat it as a 14-day trial with no end date — fine for learning the editor, useless as a home for a real list.

Can Brevo really store unlimited contacts for free?

Yes, storage is unlimited — sending is what's capped, at 300 emails per day. One broadcast to 10,000 subscribers would take about 34 days to finish on the free plan. Unlimited contacts only helps if you mail small segments or you're willing to pay from $9/month for volume.

What does Kit's free plan not include?

Visual automations, full multi-step sequences, API access and third-party integrations — all require the paid Creator plan. You keep unlimited broadcasts, forms, landing pages, tagging, broadcast A/B testing and digital product sales up to 10,000 subscribers, plus a basic welcome sequence.

Is switching from Mailchimp to Kit hard?

No — export your CSV, authenticate your domain, import with tags mapped, warm up with your most engaged segment, then overlap both tools for 30 days. Budget one afternoon for the mechanics and a week of watching bounce rates before you cancel Mailchimp.

Key Takeaways

• Winner: Kit — free up to 10,000 subscribers with unlimited sends, the strongest base for a creator list in 2026.
• Budget pick: Brevo — you pay for emails sent, not contacts stored; roughly $9–39/month depending on volume, unlimited storage.
• Skip on a budget: Mailchimp — a 250-contact free plan and about $110/month at 10,000 subscribers buy you polish, not growth.
• Automations are the real upgrade trigger — Kit's free plan can't build funnels, so the day you need one, expect to pay.
• Deliverability is mostly on you — authentication, warm-up and list hygiene beat the brand name on the tool.
• Prices move — all three repriced within the last 18 months; re-check every figure before you commit, as of October 2026.

Pick the tool that matches your list shape, not the one with the loudest ads. For most people reading this, that's Kit.
