Copy the disposable email address
Click the copy button next to the address, then paste the random email into the page where you need to register or verify. Each time you change it, you get a separate address.
The messages below are demos and are not included in the real email count.
Enter your receiving email and we’ll send a 6-digit sign-in code.
No account or password is required. Your temporary inbox is created on the first screen, making it ideal for short-term sign-ups, verification codes, and one-off tasks where you prefer not to share your real email.
Click the copy button next to the address, then paste the random email into the page where you need to register or verify. Each time you change it, you get a separate address.
New messages appear in your inbox. Verification codes usually show up in the subject or preview; refresh manually if needed.
The default lifetime is 3 hours. You can extend it by 3 hours at a time, up to 24 hours from creation.
Temporary email and permanent forwarding aliases solve different problems. Choose based on task duration, account recovery needs, and attachment size. Don’t use a temporary address for an identity that must be recoverable long term.
Use an anonymous email when trying a tool, downloading resources, or joining a one-off event to keep follow-up marketing messages separate. It can receive common text-based verification codes, though a service may still reject temporary domains.
Create a forwarding alias when you need ongoing delivery. Websites see only the alias, while messages reach your real inbox. Disable an alias individually whenever you no longer trust its source.
Temporary email is unsuitable for banking, work, government services, and paid accounts. Use a real email or forwarding alias you can control long term, so an expired address doesn’t lock you out.
Use a different alias for each site to quickly identify who leaked or misused your address. Disabling one alias won’t affect your other forwarding relationships.
TmpOne focuses on fast, low-friction email receiving. Knowing the retention period and attachment rules helps you avoid treating a temporary inbox like permanent cloud email.
Temporary credentials are stored only in your current browser. The address lasts 3 hours by default and can be extended to 24 hours from creation; expired addresses and messages cannot be recovered. Temporary inboxes don’t retain attachments, so they’re best for text notifications and verification codes.
Straight answers about verification codes, expiration, privacy, and choosing an address.
Your address is generated as soon as you open the page. Copy it into the target website, then return to the inbox and wait for the message. No registration is required; leave when you’re done or change the address to start a new isolated session.
Yes. It can receive most verification codes and confirmation links sent by email. However, the sending website decides whether to accept temporary domains, and TmpOne cannot bypass its registration rules. Use a long-term email for important accounts.
No. It lasts 3 hours by default, and each extension adds 3 hours, up to 24 hours total. Once expired, the address, credentials, and messages cannot be restored.
Both are short-term disposable email services. TmpOne provides 3 hours by default, making it better for slower confirmation emails, and lets you extend access within a 24-hour limit instead of expiring after a fixed ten minutes.
The temporary inbox does not retain attachments. If you need to receive files, use a permanent forwarding alias and note the 50MB and 100MB processing limits.
Senders see the alias, not your receiving email. The system forwards messages to you; you can create separate aliases for different sources and disable addresses you no longer need.
Trust is expensive in the temporary-email business — users hand over a receiving channel. We answer with four verifiable operating principles, not adjectives.
3-hour default, 24-hour cap, 100 aliases, 50MB per message, 30-day archive — every limit is published on the page, behaviour matches documentation, and nobody plays "unlimited" word games.
Every address on this site is receive-only. That single rule cuts spam abuse off at the root and protects deliverability for every user's address.
Mail gets automated screening and routing — no profiling, no selling, no sharing. Expired means deleted; there are no shadow copies.
When a sender blocks temporary domains, we point you to a forwarding alias instead of rotating domains to force through — short-term convenience isn't worth long-term usability.
