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.

Frequently Asked Questions
What is iSealMail?
iSealMail is a free disposable email service. Open a public inbox instantly without registration. When you need long-term ownership, claim the address as a private mailbox.
How is a temp mail different from regular email?
Temp mail requires no registration and addresses are ready instantly, ideal for one-time verification codes. Regular email requires signup with password protection and is meant for daily communication.
Can I receive verification codes?
Yes. iSealMail public inboxes can receive verification emails from most websites and apps. The page auto-refreshes to show new messages.
How long are emails kept?
Email retention depends on system configuration. Public inbox emails may be cleaned after a period. For long-term retention, claim the address as a private mailbox.
Is a public inbox safe? Can others read my mail?
Public inboxes are visible to anyone who knows the address. Do not use them for banking, medical, or sensitive mail. After claiming as private, all mail is visible only to you.
