Frequently Asked Questions
How long do disposable mailboxes stay active?
Temporary mailboxes and their corresponding stored messages are cleaned up automatically after 24 hours to protect platform resources. If you need permanent inboxes, consider creating an account and logging in to launch a YourMail inbox.
Can I send emails from a disposable address?
No, disposable inboxes are receive-only. This prevents spammers from exploiting our mail servers. For sending capabilities, authenticate via YourMail to use dedicated developer SMTP relays.
