Can You Reopen an Expired Temporary Inbox?
Learn why an expired session should be treated as finished rather than a mailbox you can depend on reopening.
Assume the old workflow is finished
An expired temporary inbox should be treated as finished. MailOnce is designed around short active sessions, not around reopening old inboxes as permanent accounts.
Reopening later is the wrong dependency
If the success of a task depends on recovering the same inbox days or weeks later, the task already has a long-term identity requirement that does not fit a short-lived address.
Future recovery changes the mailbox choice
Accounts that may need password reset, billing history, ownership proof, or support should be anchored to an address you expect to control long term.
When a permanent mailbox is the better tool
Assume expiry is final for your workflow. If you will need the address again later, use a permanent mailbox instead.
Try MailOnce
Use the current inbox while its time still matters
Open a temporary inbox for the task in front of you, watch the remaining time, and extend only when you still need the same address.
