Service Notes
Use public inboxes for low-risk receiving; claim an address when it needs long-term ownership
iSealMail separates temporary mail into two states. Public inboxes are reachable by address and fit verification codes, test messages, and one-time registrations. Claimed private mailboxes lock ownership and show historical and future mail only to the owner account.
- Address-first access
- Enter an email address to open the public inbox without registration or device binding.
- Explicit public state
- Unclaimed mailboxes are public by default; anyone who knows the address may read the messages.
- Locked after claim
- Once claimed, a mailbox cannot be released, transferred, or returned to the public pool.
Best For
Verification codes, product testing, one-time signups, low-risk notices, and confirmation mail without private data.
Public Risk
Public inboxes are not personal identity. Anyone with the address may view mail, so avoid recovery and sensitive data.
Private Claim
When the address matters long-term, use 1 quota to claim instantly. After claiming, historical and future mail is owner-only.
