Frequently Asked Questions

Can I recover my mailbox after it expires?

No. Once a mailbox expires and is deleted, all data is permanently erased and cannot be recovered. This is to protect your privacy.

How can I extend my mailbox usage time?

In Standard and Extended modes, accessing your mailbox or receiving new emails automatically extends retention time. Quick mode does not support extensions.

Why set expiration times?

Expiration mechanisms ensure the 'temporary' nature of temporary emails, protect user privacy, prevent data leaks, and optimize server performance.
