listmonk vs phpList
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.
phpList
Long-standing open-source newsletter manager for large lists.
phpList is one of the longest-running open-source newsletter applications (PHP/MySQL), built specifically for sending campaigns to large subscriber lists. It supports list management, segmentation, templates, bounce handling, and detailed sending controls, and works with any SMTP provider. It suits organizations and nonprofits that want a proven, no-frills self-hosted newsletter system and don't mind an interface that feels more utilitarian than modern SaaS tools; a paid hosted version is also available from the phpList team.

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
phpList
Strengths
- +Mature, battle-tested project focused squarely on sending to large lists
- +Solid bounce handling and fine-grained sending/throttling controls
- +Runs on a common PHP/MySQL stack that most shared hosts support
- +Self-hosted with full ownership of subscriber data
Trade-offs
- −Interface and workflows feel dated compared with modern tools
- −Limited built-in automation and visual journey building
- −You manage deliverability, an SMTP path, and PHP/MySQL upkeep yourself
- −Smaller active contributor base than the largest projects in this space
