Does MailOnce Delete Emails After an Inbox Expires?
Messages are part of the inbox-owned data graph removed when an eligible closed Free inbox is physically purged.
Quick answer
Messages are part of the inbox-owned data graph removed when an eligible closed Free inbox is physically purged.
Messages leave with the purged graph
Yes, but not instantly at expiry. Message rows and stored bodies are part of the owned graph removed when the closed Free inbox reaches purge eligibility.
For MailOnce Free, expiry or deletion closes the address first. Closed inbox data is retained for exactly 24 hours before it becomes eligible for hard purge by the cleanup worker.
Keep closure and physical purge separate
This is a bounded retention-and-purge policy, not instant deletion at the second the timer reaches zero and not permanent storage. There is currently no public immediate-purge endpoint and no Plus/account retention policy implemented in this phase.
Messages are part of the inbox-owned data graph removed when an eligible closed Free inbox is physically purged.
The practical takeaway
The useful privacy model is precise: active use, logical closure, 24-hour closed-data retention, then eligible physical purge. Messages are part of the inbox-owned data graph removed when an eligible closed Free inbox is physically purged.
