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.
