Mailchimp alternatives.

Mailchimp bills by contacts and caps your seats at three or five. Brevo bills by sends and ships a 27-module MCP server. MailerLite now advertises a plan for AI agents. Here is the field — Mailchimp, Brevo, MailerLite, listmonk, Mautic, Munin — with prices read off each vendor's own page.

A row of identical pale oak chairs stands empty against the white plaster wall of a bright modern balcony, while one chair has been pulled out to the glass balustrade where a woman sits with a coffee looking over the city — a whole set paid for, one seat actually in use.
You pay for all of them. You talk to one.

Mailchimp is the default. It has been the default for twenty years, and most of the people typing "Mailchimp alternatives" into a search box are not unhappy with the emails — they are unhappy with the bill, or with the seat count, or with the fact that the list they built lives somewhere their other tools cannot see. Those are three different problems with three different answers, and only one of them is about email.

Why do people look for a Mailchimp alternative?

Three reasons, in roughly this order. The bill is keyed to contacts you are not emailing, so a list that grows without converting is a bill that grows without converting. The plan caps how many colleagues can log in — three seats on Essentials, five on Standard. And the audience sits in Mailchimp while the support thread, the deal, and the help article sit in three other products.

None of that is a complaint about deliverability. Mailchimp sends email extremely well, has 300+ integrations, and its onboarding is better than almost anything in the category.

What does Mailchimp cost in 2026?

Mailchimp quotes by contact tier, not by a flat table. The Free plan is 250 contacts, a maximum of 500 emails a month or 250 a day, one seat, one audience, and email support for the first 30 days. At the smallest paid tier the pricing page showed Essentials at $13 a month, Standard at $20, and Premium at $350 — each an introductory rate for the first twelve months, with the post-promotional figure quoted inside the configurator rather than printed on the page.

What the plan buys you is easier to read than the price. Monthly sends scale with your list: 10× contacts on Essentials, 12× on Standard, 15× on Premium. Seats are 3, 5, and unlimited. Audiences are 3, 5, and unlimited. Automation is capped at four flow steps on Essentials and opens up to 200 flows on Standard. Exceed your contact or send limit and Mailchimp bills the overage automatically rather than pausing your campaigns, which is the humane way round. Nonprofits get 15% off, and there is a genuine pay-as-you-go credit plan for infrequent senders.

The number to model before you sign is not the monthly price. It is the shape of the curve as your list grows, because contacts is the axis the meter runs on.

Does Mailchimp have an MCP server?

Partly. Mailchimp ships an official MCP server for Transactional Messaging at https://mandrillapp.com/mcp, documented on its own developer site, exposing nine tools: account_status, build_template, call_api, describe_api, diagnose_failed_send, integrate_api, list_api, onboarding, and submit_feedback. You authenticate with a Transactional API key, and if that key is scoped you have to enable the "AI Agents" permission group for the server to work at all.

That is a developer surface for the transactional side. I could not find an official Mailchimp MCP server for the Marketing API — the audiences, campaigns, and automation flows that people actually mean when they say "Mailchimp". The MCP servers offering 90 or 115 Marketing API tools are third-party projects, and they are worth exactly the trust you place in whoever wrote them, because they are holding your API key.

This is a scope observation, not a verdict. Intuit is shipping AI into Mailchimp steadily, and Intuit Assist is available at no additional cost on Premium and Standard. But if your plan is to hand an agent the run of your marketing account, the official route is narrower than the marketing copy implies.

Every vendor in this category now has an endpoint an agent can call. Almost none of them changed what is behind it. The question moved from access to context.

Is Brevo a good Mailchimp alternative?

Yes, and it is the one I would look at first if the objection is the bill. Brevo meters emails sent, not contacts stored, which inverts the axis Mailchimp charges on. The Free plan sends up to 300 emails a day with no contact ceiling. Starter begins at 5,000 emails a month, Professional at 150,000 emails a month with 10 seats included, and Enterprise is quoted for accounts past a million contacts.

Brevo also has the most serious agent story in the category, and it deserves to be said plainly. Its official MCP server sits at mcp.brevo.com, with a main endpoint combining 27 modules and 27 individual per-module endpoints — brevo_contacts, brevo_email_campaign_management, brevo_deals, brevo_pipelines, brevo_tasks, brevo_segments and the rest — so you can hand an assistant a narrow tool surface instead of everything at once. That is a genuinely good design decision and more thought than most vendors have given it. You mint an MCP token from Account → SMTP & API → API Keys, and it is documented for Claude Desktop, Claude Code, Cursor, Windsurf, VS Code, and Cline.

Brevo is also the closest thing in this list to a whole platform rather than an email tool: campaigns, transactional, a sales CRM with deals and pipelines, live chat, loyalty, a CDP. It is French, EU-hosted, and a B Corp. If you want one commercial vendor covering marketing and sales with a well-scoped MCP surface, buy Brevo. I would not argue with that choice.

Is MailerLite cheaper than Mailchimp?

At small list sizes, yes, and the packaging is more legible. MailerLite's Free plan is $0 up to 250 subscribers with 2,500 monthly emails and two seats. Comfort is $12 a month, or $10.80 billed yearly ($129.60 a year) at up to 500 subscribers, with 5,000 monthly emails and three seats. Power is $25 a month, or $22.50 billed yearly ($270 a year) at the same tier, and it includes unlimited monthly emails and unlimited user seats. Enterprise is custom above 200,000 subscribers.

Every paid plan gets the full feature set; you pay for a bigger list or more sending, not for unlocking features. That is the cleanest pricing philosophy on this page.

And MailerLite is not pretending the world has not changed. The Power plan's own description reads: "Best for frequent senders, teams and AI agents." An MCP server is a listed feature, limited on Free, alongside named Claude and ChatGPT integrations. When a $22.50-a-month newsletter tool is selling a plan to agents, agent access has stopped being a differentiator for anyone.

What are the open-source Mailchimp alternatives?

Two that hold up, and their licences are cleaner than most of what calls itself open source in this category.

listmonk is the right answer for "a newsletter, but the list is enormous". One Go binary, PostgreSQL as the only dependency, AGPL-3.0, no enterprise directory holding features back. Segmentation is SQL expressions, which is either wonderful or disqualifying depending on who is doing the segmenting. There is no official MCP server; community ones exist, and you can point any client at its REST API yourself.

Mautic is the closest open-source equivalent to a full marketing automation platform — campaign builder, landing pages, lead scoring, multi-channel — under GPL-3.0, with no ee/ or enterprise/ directory in the repository. One edition, nothing withheld. It is PHP and Symfony and it will want a server administrator who enjoys the job.

Both end the per-contact bill. Both hand you deliverability, which the SaaS platforms were quietly solving on your behalf. Budget for an SES or Postmark relay and somebody who understands SPF, DKIM, and DMARC before you count the savings. If you want the wider open-source picture across support and CRM rather than email, the Intercom comparison and the open-source CRM roundup cover that ground.

Where does Munin fit?

Munin is not an email marketing platform, and it is on this page for a narrower reason: it is the option where the message is drafted from the same record that holds the support history, and where a person signs off before anything leaves.

CRM, Conversations, Knowledge Base, CMS, Outreach, and Analytics are six modules over one Postgres database. There is one customer row, and row-level security carries the tenant boundary. No profile sync between the CRM and the email tool, because there is no second copy of the customer to drift.

The agent reaches all six through one endpoint — 204 MCP tools at mcp.getmunin.com, with 218 REST endpoints underneath — on one credential and one audit trail. The tools that matter here are outreach_propose_first_touch, outreach_propose_followup, and outreach_propose_reply. Each writes a draft into a review queue. A person reads it, revises it with outreach_revise_proposal, and approves or withdraws. Consent lives on the contact via crm_set_contact_consent, in the same row the draft was written from. The full shape of that is in outreach that waits for your approval.

Munin is MIT licensed — not open core, not AGPL with a paid directory. Cloud Free is €0 a month with 5,000 MCP calls, 250 contacts, and 100 MB. Cloud Premium is €99 a month flat per organisation with metered overage, coming soon. Flat per organisation, not per seat, which is why the three-seat cap that starts this article does not have an equivalent here.

Which tool is this for?

Munin does not send bulk marketing email. No drag-and-drop campaign builder, no landing pages, no send-time optimisation, no shared IP pool. For a monthly newsletter to 40,000 subscribers, buy MailerLite or Brevo.

Munin is for the company whose email problem is context rather than volume — where the follow-up that is owed depends on what support said on Tuesday and what stage the deal is in. Here those sit in the same record as the draft, and nothing leaves until a person approves it.

Frequently asked questions

What is the best Mailchimp alternative in 2026? It depends on which Mailchimp problem you have. Brevo if the bill is the problem, because it meters emails sent rather than contacts stored. MailerLite if you want the same job done more cheaply and legibly at small list sizes. listmonk if you self-host and the list is enormous. Munin if the message needs to know the customer's support history before it goes out.

Is Brevo cheaper than Mailchimp? Usually, and more importantly it is cheaper in a different direction. Mailchimp's meter runs on contacts, so a list that grows without converting still raises the bill. Brevo's runs on emails sent, with no contact ceiling on the Free plan and 300 sends a day for nothing. If you hold a large list and email it rarely, that inversion is the whole saving.

Does Mailchimp have an official MCP server? Only for Transactional Messaging, at https://mandrillapp.com/mcp, with nine tools and a required "AI Agents" permission group on the API key. There is no official MCP server for the Marketing API, so any MCP offering full audiences-and-campaigns control is third-party and holds your API key.

Can an AI agent run my email marketing? It can write the emails, and with Brevo, MailerLite, or Munin it can reach the platform over MCP to do it. Whether it sends them should be your call. In Munin an agent calls outreach_propose_first_touch, which files a draft against the contact record in a review queue; a person approves, revises, or withdraws before anything leaves. Agents propose, humans decide.

Which Mailchimp alternative is best for EU data residency? Brevo is French and EU-hosted. MailerLite publishes an ISO 27001 certification and documents where data is stored. Munin is EU-hosted on Munin Cloud and MIT licensed, so you can also run it on your own hardware in your own jurisdiction. What actually stays in the region is a longer answer than any vendor badge.

How many users can I have on Mailchimp? One seat on Free, three on Essentials, five on Standard, and unlimited on Premium, which starts at $350 a month at the smallest contact tier. MailerLite Power includes unlimited seats from $22.50 a month billed yearly. Brevo Professional includes 10. Munin has no seat count on any plan.

What about Klaviyo and Customer.io? Different shape of buyer — ecommerce lifecycle and product-led SaaS respectively, both more expensive and more capable than Mailchimp at their own jobs. That comparison is here.

The short version

  • Mailchimp's Free plan is 250 contacts and 500 sends a month; paid plans are quoted by contact tier, with monthly sends at 10× to 15× your contact count and seats capped at three or five below Premium.
  • Mailchimp's official MCP server covers Transactional Messaging only — nine tools at mandrillapp.com/mcp. Full Marketing API MCP servers are third-party.
  • Brevo meters emails sent rather than contacts stored, gives 300 sends a day free, and ships an official MCP server with 27 modules and per-module endpoints for a narrower tool surface.
  • MailerLite is the clearest pricing in the category: $0 to 250 subscribers, $12 a month for Comfort, $25 for Power with unlimited sends and unlimited seats — and it sells Power to "frequent senders, teams and AI agents".
  • listmonk is AGPL-3.0 and Mautic is GPL-3.0 with no enterprise directory in either repository. Both end the per-contact bill and hand you deliverability.
  • Munin puts CRM, conversations, knowledge, content, outreach, and analytics on one customer record reachable through 204 MCP tools at a single endpoint, MIT licensed, with no seat count — and every outreach draft waits in a review queue for a person.

If the answer is a better newsletter, MailerLite and Brevo are both good and both cheap. If the answer is that the email should already know what the customer asked last week, start with Munin.

A mailing list is not a customer record. Stop paying to store one twice.
