Sessy

Sessy is an open-source, self-hosted web app and server that provides a dedicated observability layer for Amazon SES, allowing users to monitor email activity through a web interface instead of relying on the raw AWS console.

The software is deployed as a server application. It is primarily distributed via Docker for rapid deployment, though it also supports deployment through Kamal and Dokku for users who prefer to run modified versions of the codebase on their own infrastructure. This setup allows users to maintain full control over their email data while gaining visibility into their email marketing.

Key features

• Tracking of email deliveries and bounces
• Monitoring of email opens and clicks
• Tracking of recipient complaints
• Real-time search for email events
• Analytics and reputation monitoring
• Background job monitoring via a dedicated dashboard
• Support for retrying failed background jobs
• Integration with Solid Queue for task management

Built with Ruby on Rails, Sessy is designed for developers and businesses that prioritize the cost-effectiveness and reliability of raw Amazon SES but require a more accessible way to analyze delivery metrics. The application functions by capturing and displaying the events that occur after an email is dispatched, turning raw SES data into actionable insights. To ensure stability, the system includes a jobs dashboard located at the /jobs endpoint, which allows administrators to monitor queues, manage recurring tasks, and troubleshoot failed background processes.

Sessy is a specialized observability tool for those who want to maintain professional grade monitoring of their email communication streams.
