Terms of Use
Last updated: 4 August 2026.
Using TempMailbox means accepting what is on this page. The page is short because the service is small: you take an address, mail arrives, the address expires. Most of what follows is about the edges of that sentence.
What you get
A mailbox that receives messages, free of charge, with no account required, on a domain we control and rotate. It is supplied exactly as it stands, with the behaviour described on the about page and nothing promised past that.
Addresses and messages are temporary by construction. When the clock runs out they are deleted, and afterwards nobody can produce them: not you, not us, and not anyone arriving with a demand.
Receiving only
You cannot send mail from an address created here, and no later version will change that. It is not an unfinished feature. Anonymous sending would turn this into a spam relay within days, its domains would be refused everywhere within weeks, and the receiving half would die alongside them. The restriction is what keeps the rest of the service functioning.
Anything that appears to come from one of our domains was forged elsewhere. The contact page explains what to send us if that is why you are here.
No API and no automated access
There is no API, no feed and no endpoint meant for programmatic use. Do not script the site, drive it with a headless browser, or scrape mailbox contents. Traffic that looks automated is throttled first and blocked after that.
This is not gatekeeping for its own sake. A script produces addresses far faster than a person can, and address creation on a public domain is precisely what gets that domain noticed and listed.
Bulk address generation is a breach
Creating addresses in volume, by hand or by tool, breaks these terms. Every domain in the public pool has a finite working life, and mass generation burns through it for everybody using the site normally. One person automating signups can cost a domain months of usefulness for thousands of others.
What you may not use the service for
Do not use it for anything unlawful where you are, to threaten or harass another person, or to take delivery of material that is illegal to hold.
Do not use it to defraud anyone, to get around a ban, or to open accounts in bulk on another website against that website's rules. A site rule and a law are different things with different consequences, and this service is meant for neither.
Do not try to overload, probe or interfere with the service, and do not go looking through mailboxes that are not yours. A guest mailbox having no lock is a property of the design, not an invitation.
What we may do
We may delete any mailbox at any moment, including one you are using, without saying which or why. We may block an address, a domain or a range of traffic that looks abusive. We may retire a mail domain, which stops new addresses being issued on it.
These are operational powers for keeping the service alive rather than disciplinary ones, and in practice they land on automated abuse far more often than on people.
What is not promised
Availability. The service can be slow, down, or interrupted for maintenance with no notice. It is free and carries no uptime commitment of any kind.
Delivery. Some senders refuse to deliver to disposable domains and we usually cannot tell that they tried. A verification code that never arrives is most often this, and another domain is the practical answer.
Continuity. The service may change or stop altogether, and whatever sits in a mailbox goes with it.
Suitability for anything that matters. Do not attach an address from here to an account you will one day need to recover. That risk is yours, and the disclaimer sets out where the line falls.
Accounts
A free account adds longer retention, ten mailboxes, unpublished domains, attachments and mailbox privacy. It costs nothing and there is no paid tier above it. Keep the password to yourself, because whoever holds it holds every mailbox in the account. An account used to break these terms can be closed.
Advertising
Advertising pays for the service, which is why it is free. Ads sit in space reserved before they load so the page does not jump while you read, and no ad is allowed to imitate a control on the site. We do not accept advertising that has to be mistaken for something else in order to work.
Liability
To the fullest extent your local law allows, we are not liable for loss arising from use of this service: lost messages, lost accounts, codes that never arrived, or the consequences of somebody else opening a guest mailbox. If a court finds some liability unavoidable, it is capped at what you have paid us, which is nothing.
Changes to these terms
These terms will change as the service does. When they do the date at the top moves and the new version applies from that day. In practice we will not write to you about it, so check the page occasionally if the rules matter to you, and continuing to use the service after a change is how you accept it. Anything materially stricter will be stated plainly here rather than buried in a paragraph.
