listmonk removes every limit and hands you the delivery bill
There is no subscriber cap and no send cap, because there is no vendor to set one. listmonk is one Go binary against a Postgres database, licensed AGPL-3.0, and it will happily manage a list of any size for nothing.
Then it hands the campaign to somebody else. listmonk does not deliver email. It queues your messages to an SMTP provider you supply and pay, which means the two axes this whole category prices on still cost money, just not to listmonk. That distinction is the entire page.

68 out of 100, carried by the freedom pillar
68 puts listmonk in the Usable band, which looks low for a tool with no limits until you see where the points come from. Freedom scores 88, the highest in this category by a wide margin: your list is a Postgres table on your own server, there is no branding, no quota anyone can switch off, and export is whatever you can write a SELECT for.
Generosity is 76 rather than a perfect mark precisely because uncapped is not the same as free. Feature depth at 55 is the other weight, and it is a fair one against this category rather than against software generally: the hosted tools here give away landing pages, popups and A/B testing that listmonk does not have at any price. And user sentiment sits at 50 by default because we hold no G2, Trustpilot or Capterra score for listmonk at all, which the reasoning below says plainly rather than substituting GitHub stars for user reports.

Usable
No limits on the software, and every email still costs you at an SMTP provider.
- Free plan generosity35% of the score
76/100
No subscriber cap and no send cap, because there is no vendor to set one. The counterweight is the whole story though: listmonk does not deliver mail, so both of this category's axes cost real money at Amazon SES, Postmark or Mailgun, plus a small VPS. Uncapped is not the same as free, and at 100,000 emails you are paying somebody, just not listmonk.
- Feature depth for the category25% of the score
55/100
Subscribers, campaigns, templates, analytics, transactional sending and SQL-based segmentation, all uncapped, and fast enough that the project documents a seven million email campaign on under one CPU core. Against what this category gives away free the gaps are real: no landing pages, no popups, no A/B testing, no paid subscriptions, and segmentation assumes you can write SQL.
- Freedom and honesty20% of the score
88/100
The strongest position here. Your list is a Postgres table on your own server under AGPL-3.0, there is no vendor branding, no quota anyone can switch off, and export is whatever you can SELECT. The caveat we will not skip past: this is free if you can run Docker and configure DNS, because SPF, DKIM, bounce handling and blocklist trouble all become your job rather than a vendor's.
- What free users report20% of the score
50/100
We hold no G2, Trustpilot or Capterra score for listmonk at all, so we have nothing to report about what its users think. It sits at the middle by default, and we are not treating GitHub popularity as a stand-in for user reports.

No software limits, and four jobs that quietly become yours
Nothing in listmonk counts down. What replaces the limits is work, and this is the part the word free hides:
- You own deliverability. SPF, DKIM, DMARC, warming a sending IP, handling bounces, getting off blocklists. On a hosted tool this is a vendor's problem, and their reputation team is the product you were really paying for.
- You supply and pay an SMTP provider. Amazon SES, Postmark and Mailgun are the usual choices, and every email you send costs money at whichever one you pick. We are not quoting their rates, because those prices are not facts we hold in this repo.
- You run a server. A small VPS is enough (the project documents a campaign of over seven million emails on under one CPU core and 57 MB of RAM), plus PostgreSQL 12 or newer, plus backups and upgrades nobody else will do.
- Support is a GitHub issue tracker and a community forum, not a helpdesk with a response time.
The feature gaps are simpler to state: no landing pages, no popups, no A/B testing, no paid subscriptions, and segmentation is done with raw SQL against your subscriber table. That last one is a genuine advantage if you write SQL and a wall if you do not.
The software is $0. Here is the invoice you actually get
There is no pricing ladder to explain, so the honest version of this section is a shopping list. A small VPS, a Postgres database on it or beside it, and an account with an email sending provider that bills you per message. That is the real cost of listmonk, and only the third item scales with your success.
The comparison that matters is against per-subscriber pricing rather than against zero. Every hosted tool in this category charges you for storing addresses, sending to them, or both. listmonk charges for neither and passes only the delivery cost through at wholesale, which is why it gets cheaper relative to everything else the larger your list grows. At a few hundred subscribers this arrangement saves you nothing and costs you an afternoon. At six figures it is the cheapest serious option that exists.
There is also no upgrade to be sold. Nothing is held back, nothing expires, and no part of the product is waiting behind a plan name. That is worth something on a site full of free tiers designed to run out.
One useful middle path if this appeals but the server does not: EmailOctopus's free plan has an option to route through your own Amazon SES account, which gets you the wholesale delivery rate without anything to administer.

Is listmonk really free? The software is. The sending is not
A real free plan with a ceiling you will meet. Fine until you grow into it.
Yes, within limits, and the limit is not a number in the product. We are departing from the usual reading of an uncapped open-source tool here on purpose: listmonk never charges you and never stops you, but it also never sends an email, so zero dollars buys you a list manager and no delivery. Anyone answering "is listmonk free" without that sentence is answering the wrong question.
Who genuinely runs it for near nothing: a developer with an existing server and an SES account, a technical team whose list outgrew per-contact pricing years ago, an organisation with data residency rules that rule out US-hosted vendors, anyone who wants their subscriber list to be a table they own outright.
Who should not: anyone who does not want to be the person on call when messages start bouncing. The gap between listmonk and a hosted free plan is not features, it is who gets paged. If configuring DNS records is not a normal afternoon for you, Brevo's free plan will treat you better than this will.
Free listmonk alternatives covers the hosted end, and the best free email marketing tools ranks the category with both routes side by side.
Frequently asked questions about listmonk
Is listmonk actually free?
The software is, under AGPL-3.0, with no subscriber or sending limits. Running it is not. You need a small server and an email sending provider such as Amazon SES, Postmark or Mailgun, and you pay that provider per email, so your bill is hosting plus delivery rather than a subscription.
Does listmonk send the emails itself?
No, and it is the detail most people miss. listmonk manages subscribers, segments and campaigns, then queues them to SMTP servers you configure. Delivery, and therefore deliverability, belongs to whichever provider you plug in and ultimately to you.
What do I need to run listmonk?
A single binary and a PostgreSQL 12 or newer database, with an official Docker setup available. It is light enough that a small VPS handles very large campaigns: the project documents over seven million emails sent on less than one CPU core.
