Built for Developers & QA Testers

un.limited.mx is designed for software developers and QA engineers who need to create and manage lots of sign-up accounts for testing purposes. Instantly generate unlimited email addresses for every test case, environment, or automation run—no more inbox clutter, no more manual cleanup. Perfect for CI/CD, staging, and automated user flows.

Free. No credit card required.

More than an inbox

✅ Deliverability Checks

Every email is graded Pass Warn Fail using its SpamAssassin score, DKIM, SPF and DMARC results, plus content checks for the things that hurt inbox placement — missing plain-text parts, suspicious links, spammy subjects.

Catch deliverability problems in staging, not in production.

🔔 Webhooks & CI

Get an HMAC-signed webhook the moment an email arrives, or make your pipeline wait for one with a single API call — and fail the build if it never comes or doesn't pass deliverability.

GET /api/emails/wait?to=you+ci-123…&requireGrade=Pass

🔗 Shareable Test Links

QA found a broken email? Create an expiring, revocable link and hand the exact email — rendered preview, extracted links and deliverability report — to a developer. No screenshots, no login needed to view.

Links expire automatically and can be revoked at any time.
