Overview

Sessy is an open-source dashboard for AWS SES email events. You create an SES configuration set and point its SNS destination at a Sessy webhook URL; sends, deliveries, bounces, complaints, opens, clicks, rejects, delays and rendering failures then appear in real time, searchable by recipient or subject. Run it with Docker or Kamal on your own server, or use the hosted version.

Best for: Developers sending through AWS SES who want delivery, bounce and engagement tracking they host themselves
Pricing: Self-hosting is free and open source, and the hosted version is free while it is in early-access beta; no prices are shown for after the beta.
Runs on: Self-hosted

Strengths and trade-offs

Strengths

Deploys with one Docker command; SQLite or PostgreSQL, no external deps
Captures all major SES events, including bounces, opens and clicks
Read-only MCP server lets Claude Code, Cursor and Codex query events
Self-hosting is free and open source, with no volume or retention caps

Trade-offs

Works only with AWS SES; no other email providers are mentioned
Hosted version is in beta and pricing after early access is not stated
Self-hosting means running and updating the server yourself
Described as under active development, so behaviour will keep changing
