listmonk vs Mautic
Both are free/open-source alternatives to Mailchimp. Here's how they stack up — verified facts, no spin.
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.

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
