What you need to know before using these addresses

01 / Service scope

First, understand the difference between temporary inboxes and forwarding

Tenminbox offers temporary inboxes that don’t require sign-in, and forwarding aliases managed after you sign in with a verification code sent to your real email. Temporary inbox messages appear on the website. Eligible messages sent to forwarding aliases go to the real email you use to sign in. Each account can have up to 100 aliases.

Messages sent to forwarding aliases are archived online for 30 days, including spam that was filtered. Temporary inboxes and forwarding aliases are for receiving email only; you can’t send or reply from these addresses. This service is not a permanent email backup.

“Tenminbox” is the product name. It does not mean an address lasts only ten minutes or stays active forever. Check the expiry time shown in the temporary inbox; alias message retention and temporary address expiry are calculated separately.

02 / Acceptable use

Allowed: use separate addresses for legitimate email

Where permitted by law and the other website’s rules, you may use these addresses to receive verification codes or shopping notifications, or to test email workflows you’re responsible for. Creating an address does not give you permission to register, access or test a third-party website.

For accounts you need to access, appeal or recover over the long term, keep a reliable email address and other recovery methods under your control. Verify your new email address with the website before changing it; don’t wait until a temporary address expires.

• Short-term sign-ups and verification codes Use a temporary inbox to receive a one-time code, then leave once you’ve completed the action. If a website requires a long-term email address, provide one as requested.
• Ongoing shopping notifications Use a different forwarding alias for each retailer to keep order and after-sales messages organised. Check regularly that notifications haven’t been filtered by mistake.
• Development and operational testing Test verification codes, email content and notification workflows only on systems you’re authorised to test. Keep request rates reasonable; don’t use the service for stress testing or bulk abuse.

03 / Prohibited conduct

Not allowed: don’t use the service to enable abuse

You must not use Tenminbox for illegal activity or to violate anyone’s privacy, property or other legal rights. These restrictions apply to temporary addresses, forwarding aliases, accounts and related interfaces. Creating addresses in bulk does not get around them.

We may take reasonable steps to address abuse, security risks or violations of these terms, including limiting requests, disabling addresses or suspending account access. Don’t use these addresses for actions that require you to bypass someone else’s rules.

• No illegal activity Don’t use an address or account to receive, organise or assist with transactions or activities prohibited by law.
• No fraud or impersonation Don’t use the service for phishing, identity theft, fraudulent transactions, or to trick anyone into sharing verification codes, money or access credentials.
• No harassment Don’t repeatedly sign up, bombard anyone with notifications or otherwise keep sending them unwanted messages.
• No spam operations Don’t collect or verify addresses for spam, receive verification codes in bulk, or help send unsolicited email.
• No bypassing access restrictions Don’t evade bans, identity checks, quotas, or access and registration limits set by third-party platforms.
• No disruption or interference Don’t carry out malicious stress tests, access other people’s email, try to steal credentials, interfere with interfaces or exploit vulnerabilities to access data without authorisation.

04 / Accounts and credentials

Your real email is your key—keep control of it

Sign in with a real email address you’re authorised to use and can keep control of. It receives your login verification codes and forwarded messages. If you lose access to it, you may also lose access to your account and forwarded messages. Protect its password, recovery options and two-step verification.

Never share login verification codes, authenticator codes, temporary inbox access credentials or account login credentials. Don’t publish links that contain access credentials. Anyone with valid temporary inbox credentials may be able to view its messages. Before sharing a screen, browser profile or device, make sure you won’t expose messages or credentials.

On a public device, sign out of your forwarding account and clear browsing data if the device allows it. Destroy temporary inboxes you no longer need from the inbox itself—signing out of your account does not clear them. For accounts you use long term, you can enable two-step verification in the Forwarding Dashboard as needed.

05 / Delivery and storage limits

You can check for messages, but delivery isn’t guaranteed

Third-party websites may reject temporary addresses or aliases, or may not send messages because of their own security checks, sending rules or network conditions. Delivery can also be affected by the sender, transmission systems, receiving servers and your real email provider. Messages may be delayed, bounced or fail to arrive. Tenminbox does not guarantee delivery of every message or a fixed delivery time.

Spam filtering may incorrectly block legitimate notifications or let unwanted messages through. You can sign in to check archived messages during the 30-day retention period, including messages that were filtered. The archive only shows messages the service actually received and stored; it can’t recover messages that never arrived.

If a verification code doesn’t arrive, check the address spelling, the temporary inbox’s remaining time and any instructions on the sender’s website. Then check the archive or your real email’s spam folder. Don’t request codes repeatedly in a short period. If needed, contact the sender or switch to a reliable long-term email address if their rules allow it.

For important actions such as payments or account recovery, verify who sent the message and where the action came from. Don’t assume a message is trustworthy just because it reached your inbox or was forwarded. For ways to separate email sources, see how to trace the source of spam. An alias can help you identify a source, but it doesn’t prove that a website sold your address.

06 / Disabling, deletion and service changes

Before you stop receiving messages, move important contacts

Once you disable a forwarding alias, new messages won’t be forwarded and will be discarded. Don’t expect them to appear in the archive. Existing archived messages remain subject to their retention period and deletion. If you still need messages from a website, update your email address there before disabling or deleting the alias.

Deleting archived messages only removes the corresponding records from this service. It won’t recall copies already delivered to your real email, downloaded or saved by other recipients. Destroying a temporary inbox invalidates its old address and access. After switching to a new temporary address, don’t expect messages at the old one. Save anything you need before taking these actions.

To keep the service secure and running properly, we may set reasonable request rates, account quotas and usage limits. The service may also be temporarily unavailable due to maintenance, outages or security incidents. We make no uptime, delivery success or compensation promises beyond those expressly stated on this page. Nothing in these terms excludes rights or liabilities that applicable law does not allow us to exclude.

We’ll update this page and show the date when these terms or service rules change. Changes to important usage limits will also be noted on the relevant service pages. Check the latest information before continuing to use the service. If you don’t accept the changes, you can stop using it. Before disabling, deleting or destroying anything, export what you need to keep and update any linked email addresses.
