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.
