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

How this score is made up

Each dimension is scored out of 100 and combined into the headline score using fixed weights.

  • MCP support

    Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.

  • API quality

    Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.

  • Documentation

    Publicly reachable docs — coverage, freshness, code samples and machine readability.

  • Agent friendliness

    How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.

  • Changelog

    A public, dated record of what shipped and when — the clearest signal that a product is still alive.

  • Marketing site structure

    Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.

  • Page speed

    How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.

  • Operational trust

    Status page and incident history, security disclosure, compliance and data-processing documentation.

Measured, but not part of the score

Useful to know, but not a mark for or against the product — so these do not affect the ranking.

  • Openness

    Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.

  • Maintenance

    Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.

Where this comes from

The Sessy pages BenchRank reads when it scores the product — its documentation, release notes, status and security pages, and its repository where there is one.
