About
How Debug Mail work
The service provides command-line access to the virtual SMTP-server. The sender and receiver addresses can be anything, since no real mailings are sent.
The technology used by application developers does not matter, the service will work with PHP, Python, Ruby, Node.js, .NET and many other programming languages and frameworks.
Sharing options
Sharing is the main feature of Debug Mail. To see what the service and other mailings will look like, just connect the right users to the project in the service, and they will see the same thing as the developer who is testing the mailing.
What you can do in Debug Mail
- Send emails to non-existent test addresses instead of real ones.
- Set up email distribution lists with colleagues using team access.
- Work together with other developers on the service.

About
Zyntra is a disposable email platform for QA teams and test automation workflows.
It helps you capture, assert, and validate email content as part of your end-to-end tests — without manual setup or flaky workarounds.
Use it to:
• Generate unlimited private inboxes automatically, with one line of code
• Trigger real emails (OTP, password resets, invites) and read them via API or Web viewer
• Prevent test emails from leaking to real users — all inboxes are private by default
• Run isolated tests in CI/CD with no collisions or cleanup
• Validate your entire email-based flow, just like in production (real SMTP)
Zyntra works with any testing framework or language and includes an official Node.js SDK for fast integration. Ephemeral inboxes are retained for 24 hours; persistent ones for at least 7 days.
Built by QA, for QA — Zyntra helps you stop babysitting test environments and focus on verifying what matters.
