EagleCast

EagleCast is a standalone, self-hosted newsletter and mailing list manager with a sharp eye and serious wingspan. It is fast, feature-rich, and packed into a single binary. It uses a PostgreSQL database as its data store.

Send campaigns that soar: manage millions of subscribers across lists, run opt-in and transactional mailing, template with precision, and track every landing — all from one nest.

Features

Multiple lists, single and double opt-in
Powerful subscriber querying and segmentation with SQL
Rich campaign templating (HTML, Markdown, plain text, and a visual builder)
Transactional mailing API
Bounce processing (SES, SendGrid, Postmark, Forward Email, POP3, and more)
Media management with filesystem or S3 storage
Multi-user support with roles and granular permissions
OIDC single sign-on
Public archive pages and RSS
Available in 35+ languages

Installation

Docker

Build the image locally and run the sample docker-compose.yml:

# Build the eaglecast image.
make dist && docker build -t eaglecast:latest .

# Run the services in the background.
docker compose up -d

Visit http://localhost:9000

Binary

Build from source with make dist (requires go, nodejs, and yarn), producing the eaglecast binary.
./eaglecast --new-config to generate config.toml. Edit it.
./eaglecast --install to setup the Postgres DB (or --upgrade to upgrade an existing DB. Upgrades are idempotent and running them multiple times have no side effects).
Run ./eaglecast and visit http://localhost:9000
