Managed Email & newsletters
The open-source Mailchimp / Klaviyo alternative — deployed, branded, and run for you. Own your data, with no per-seat fees.
What It Is
Self-hosted email at any scale.
Listmonk is a high-performance, self-hosted newsletter and mailing-list manager. It manages lists, subscribers, campaigns, and transactional email from a single application you run yourself — built to handle very large lists efficiently.
Mailchimp and Klaviyo price by contact count and send volume, so your bill rises as your list grows. Managed Listmonk replaces that with a flat monthly fee — grow your list to millions without per-contact pricing.
Key Features
Everything in the official build — managed and kept current by us.
Single and double opt-in lists with powerful SQL-based subscriber segmentation.
Author with drag-and-drop, WYSIWYG, Markdown, or raw HTML templates.
Multi-SMTP, multi-threaded queues with rate limiting for large sends.
Send transactional messages via a simple API using predefined templates.
Track campaign performance, bounces, and top links.
Designed to handle millions of subscribers on modest hardware.
Why Managed
You get the tool without the DevOps.
We install the official build on your infrastructure and brand it with your logo, colors, and domain.
SSL, access controls, and sensible hardening so it is production-ready from day one.
Automated backups so your data is safe and recoverable.
Health checks and monitoring keep it online without you watching it.
A real person to call when you need a change or hit an issue.
Add a Claude or Hermes automation layer on top via the official API — entirely separate from the app itself.
Pricing
Flat and transparent. Annual prepay gets you roughly two months free.
Listmonk is open source (AGPL-3.0). We deploy the official build unmodified and brand it through its own settings — we don’t fork or patch the source. Your instance runs on your server with your data, and if you ever leave you keep the instance plus a runbook to carry on without us. Any AI or automation we add is a separate service that talks to Listmonk through its official API.
FAQ
Common questions about managed Listmonk
Yes. Listmonk is open source and runs on infrastructure you control. Your instance, your server, your data — we operate it for you, but it is yours.
You keep the instance and your data, plus a documented runbook for running it yourself or handing it to another provider. No lock-in.
That is the point. Unlike Mailchimp, there is no per-seat or per-contact tax — add users and grow usage on a flat monthly fee.
Yes. We can layer Claude or a Hermes AI employee on top through Listmonk's official API — a separate service that talks to the app, so the open-source build stays unmodified.
Usually, yes. Data migration from your current Mailchimp (or similar) setup is available as an add-on — we scope it with you up front.
Book a call and we’ll stand up a branded Listmonk on your infrastructure — and migrate your data if you have it.
