Frequently asked

How much does it cost?

Free and open source. Self-host on your own infrastructure. A hosted version is coming for those who prefer a managed solution.

How do I set it up?

Deploy Sessy, then configure a webhook URL in your AWS SES settings. Events flow automatically. No AWS credentials required.

What database does it use?

SQLite by default, with PostgreSQL support. No external dependencies. Your data stays on your server.

Can I use this in production?

Yes. Sessy is already running in production at multiple companies. It's under active development, so expect improvements.

What events can be tracked?

All major SES events: sends, deliveries, bounces, complaints, opens, clicks, rejects, delays, rendering failures, and subscriptions.
