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.

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

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
