Perimattic Managed Listmonk - Newsletter Manager on AWS

This AMI runs Listmonk, the open-source newsletter and mailing-list manager, with PostgreSQL 17 on Ubuntu 24.04 LTS. The official Listmonk image is pinned to 6.2.0, with PostgreSQL 17.11, and baked into the AMI, so first start does not depend on a registry. Listmonk is an independent open-source project and Perimattic is not affiliated with it; product names are trademarks of their respective owners.

Why Listmonk?

Listmonk manages subscribers, lists, templates and campaigns for newsletters and transactional messages, with a built-in subscription form, double opt-in, segmentation, bounce handling, analytics and a REST API. It is a single, light application.

What Perimattic adds

Admin created for you: a fresh Listmonk lets the first visitor claim the Super Admin account. During first-login setup this AMI runs Listmonk's install with a random 24-character admin password generated on your server, before the site is published, so nobody can claim it, and the password is given to that one install command only. Setup then points Listmonk's root URL at your domain, switches off its update check, and checks that the password works, that a wrong password and anonymous requests to the admin and API are refused and that exactly one account exists. There are no default or shared credentials in the image.

HTTPS: Apache is configured as a reverse proxy and a free Let's Encrypt certificate is requested for your domain with certbot. Listmonk listens only on the loopback interface and PostgreSQL is reachable only inside the Docker network.

Patched base: Ubuntu 24.04 LTS built through an automated EC2 Image Builder pipeline, with security updates applied at build time.

What you should know

No mail server is configured. The admin interface and the API work, so you can build lists, import subscribers and write campaigns, but Listmonk cannot send any email until you enter your own SMTP server (Amazon SES, your provider or any relay) under Admin > Settings > SMTP. Amazon EC2 blocks outbound port 25 by default; use port 587 or 465.

Some pages are public by design, because subscribers use them: the subscription form, unsubscribe and preference pages, the public campaign archive, and the list of lists you mark public. Everything under /admin and the rest of the API need the login. A fresh install includes example lists and two example subscribers that you can delete.

Listmonk is light: about 30 to 50 MB of memory and about 60 MB for PostgreSQL in our tests, so a t3.small (2 GB) is the recommended starting size; large lists and campaigns need more.

Licence

Listmonk is released under the GNU Affero General Public License v3.0 (AGPL-3.0); this AMI runs the unmodified upstream image, whose source is at github.com/knadh/listmonk. PostgreSQL is released under the PostgreSQL License.

Getting Started Launch the AMI and open ports 22, 80 and 443 in the security group SSH in and answer the setup prompts (domain and admin email) Open https://your-domain/admin  and sign in as admin with the password printed at the end of setup Enter your SMTP server under Settings to start sending

A domain name with an A record pointing at the instance is required, because the site is served over HTTPS.
