listmonk vs Mautic
Both are alternatives to Mailchimp. Here's how they stack up — verified facts, no spin.
Also searched as Mautic vs listmonk — same comparison, one verdict.
Both are email marketing & newsletters tools with the same broad shape, but listmonk scores 92 against Mautic's 84 on data ownership and exit cost — the gap is in how easily you could leave.
listmonk
TOP PICKFast, self-hosted newsletter and mailing-list manager in a single binary.
listmonk is a self-hosted newsletter and mailing-list manager written in Go, distributed as a single binary backed by PostgreSQL. It handles large lists, subscriber management, custom fields, segmentation, templated campaigns, and click/open analytics, and sends through any SMTP provider you choose (such as Amazon SES, Postmark, or your own relay). It exposes a full HTTP API and a clean admin UI, and is a strong fit for teams and technically comfortable individuals who want to own their subscriber data and keep sending costs to whatever their SMTP provider charges.
Mautic
Full open-source marketing automation platform.
Mautic is a mature open-source marketing-automation platform (PHP/Symfony) that goes well beyond newsletters, offering contact management, segmentation, visual campaign/journey builders, landing pages, forms, lead scoring, and multi-channel messaging. It is the closest open-source counterpart to Mailchimp's higher tiers for teams that need automation depth, and it sends through your chosen SMTP or transactional provider. It rewards organizations willing to run and maintain a more substantial application in exchange for owning their data and automation stack.

| Realistic running costWhat the box costs each month if you run it yourself. | $6/mo plus SMTP relay costs, against Mailchimp pricing that scales per subscriber | $12–48/mo on a 4–8 GB VPS, plus an email service: Amazon SES is $0.10 per 1,000 emails |

Mautic 7 (January 2026) raised the minimum to PHP 8.2 and MySQL 8.4 or MariaDB 10.11, and removed in-browser updates. |
listmonk is Macrostack's recommended Mailchimp alternative, so it's our pick here.

listmonk
Strengths
- +Single Go binary plus PostgreSQL — straightforward to deploy and low on resources
- +Bring your own SMTP provider, so sending cost is decoupled from any one vendor
- +Full REST API, custom fields, segmentation, and template management
- +Actively maintained with a large community (20,000+ GitHub stars)
- +Your subscriber data stays entirely on infrastructure you control
Trade-offs
- −You are responsible for email deliverability, SPF/DKIM/DMARC setup, and an SMTP relay
- −No built-in visual customer-journey/automation builder as deep as Mailchimp's
- −Requires comfort running a server and PostgreSQL — not a click-to-start hosted service
- −AGPL-3.0 imposes source-sharing obligations if you offer a modified version as a network service
Mautic
Strengths
- +Closest open-source match to full marketing automation and customer journeys
- +Landing pages, forms, lead scoring, and multi-channel campaigns built in
- +Large, established community and plugin ecosystem
- +Self-hosted, so contacts and automation logic stay on your infrastructure
Trade-offs
- −Heavier PHP/Symfony stack with more moving parts to install and maintain
- −Steeper learning curve than a simple newsletter tool
- −Deliverability and an external sending provider are still your responsibility
- −Ongoing upkeep (updates, cron, queues) is more demanding than a single-binary app
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose listmonk
if a lower exit cost matters more to you than any single feature, and single Go binary plus PostgreSQL — straightforward to deploy and low on resources.
Choose Mautic
if closest open-source match to full marketing automation and customer journeys.
Neither, yet
if both carry a real cost you should weigh first — you are responsible for email deliverability, SPF/DKIM/DMARC setup, and an SMTP relay, and heavier PHP/Symfony stack with more moving parts to install and maintain. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.

listmonk vs Mautic — common questions
Is listmonk a better fit than Mautic for email marketing & newsletters?
It depends on what you are optimising for, and the honest split is this: listmonk scores 92 to Mautic's 84 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Mautic earns its place on a different axis — closest open-source match to full marketing automation and customer journeys. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
listmonk keeps its data local or in open formats, so leaving is an export rather than a negotiation. Mautic is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host listmonk or Mautic?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are listmonk and Mautic both alternatives to Mailchimp?
Yes — both appear in our Mailchimp comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Mailchimp and now choosing between the two replacements, which is a narrower and much easier question.
