Geoposler

Geoposler is a Dockerized email campaign management application for creating and sending HTML-based email campaigns. It provides a React-based admin UI and a TypeScript/Node.js backend, and stores campaign data in a MySQL database.

Key Features

• Create, edit and manage HTML email templates
• Manage contact lists and basic contact metadata
• Send HTML emails through configurable SMTP parameters
• Persistent storage using MySQL for templates, contacts, and campaign data
• Frontend built with Vite, React and Tailwind CSS; backend written in TypeScript/Node.js
• Distributed via Docker and Docker Compose for easy deployment; expects a healthy MySQL service

Use Cases

• Small businesses or projects sending newsletters and announcements using their SMTP provider
• Developers or teams testing and previewing HTML email templates against an SMTP server
• Self-hosted campaign management for organizations that require on-premise control of contact data

Limitations and Considerations

• Lacks built-in deliverability features such as DKIM signing, bounce handling, or advanced analytics
• No built-in campaign scheduling, detailed tracking, or unsubscribe management documented
• Relies on an external SMTP server for delivery; deliverability and rate limiting are dependent on that provider

Geoposler is suitable for straightforward, self-hosted email campaigns where control over templates and contacts is required. It provides a lightweight, containerized stack but may need extensions or integrations for production-grade deliverability and tracking.
