Zyntra

Unlimited mailboxes for QA teams with API and UI access

Visit

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.
