Zyntra
Unlimited mailboxes for QA teams with API and UI access
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.
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.
Features
- Unlimited e-mail addresses
- Ephemeral and permanent mailboxes
- 7+ days retention for permanent test mailboxes
- API access
- Web viewer
- Node SDK
Use Cases
- Generate unlimited private inboxes automatically, with one line of code
- Trigger real emails (OTP, password resets, invites) and read them via API or UI
- 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)
