Questions & Answers

How long does a test inbox last?

Each inbox lives for 1 hour. After expiration, all emails, attachments, and address data are permanently deleted — nothing is retained.

What can I test with mail.td?

Account verification flows, transactional emails, notification pipelines, webhook integrations, and more. Mail.td works in staging, CI/CD, and production environments.

Is it free?

The core testing service is completely free. Pro plans add custom domains, API tokens, and webhooks for team and platform-level workflows.

Is test data isolated?

Yes. Each inbox is independent and auto-deleted after expiration. We do not use tracking cookies, advertising identifiers, or third-party analytics. Data is retained only as long as necessary to operate the service.
