Terms of Use

Last updated: 3 August 2026.

Using CrazyMailing means accepting what is on this page. It is short because the service is small: you take an address, mail arrives, the address expires. What follows is mostly about the edges of that.

What you are getting

A mailbox that receives messages, at no charge, with no account required, on a domain we control. It is provided as it stands, with the behaviour described on the about page and nothing promised beyond that.

Addresses and messages are temporary by construction. When the clock runs out they are deleted and cannot be brought back by you, by us, or by anyone presenting a demand for them.

Receiving only

You cannot send mail from an address created here, and no future version will change that. It is not a missing feature. Anonymous sending turns a service like this into a spam relay in days, its domains get blocked everywhere in weeks, and the receiving side dies with them. The restriction is the reason the rest of the service works.

Anything that appears to come from one of our domains was forged elsewhere. If that is why you are here, the contact page explains what to send.

No API, and no automated access

There is no API, no feed and no endpoint for programmatic use. Do not script the site, drive it with a headless browser, or scrape mailbox contents. Requests that look automated are throttled and then blocked.

This is not gatekeeping for its own sake. A script creates addresses far faster than a person can, and address creation is exactly what gets a domain noticed and listed.

Bulk address generation is not allowed

Creating addresses in volume, whether by hand or by tool, is a breach of these terms. Every domain in the public pool has a finite life, and mass generation shortens it for everyone using the site normally. One person automating registrations can cost a domain months of usefulness for thousands of others.

What you may not use the service for

Do not use it to break the law where you are, to harass, threaten or deceive anyone, or to receive material that is illegal to possess.

Do not use it to defraud anyone, to evade a ban, or to open accounts in bulk on another website in breach of that website's rules. The difference between a site rule and a law is real, and we have written about it in is disposable email legal, but this service exists to get around neither.

Do not attempt to overload, probe or interfere with the service, and do not try to reach mailboxes that are not yours. A guest mailbox being unlocked is a property of the design, not an invitation to go looking through them.

What we may do

We may delete any mailbox at any time, including yours, without explaining 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, not disciplinary ones, and in practice they are used against automated abuse far more often than against people.

What is not promised

Availability. The service can be down, slow, or interrupted for maintenance without notice. It is free and carries no uptime commitment.

Delivery. Some senders refuse to deliver to disposable domains, and we usually cannot tell that they tried. If a verification code never arrives, that is the likeliest reason, and another domain is the practical answer.

Continuity. The service may change or stop entirely, and whatever is in your mailbox goes with it.

Suitability for anything important. Do not attach a disposable address 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 gives longer retention, ten mailboxes, unpublished domains, attachments and privacy. It costs nothing and there is no paid tier above it. Keep your password to yourself: anyone holding it holds every mailbox in the account. We can close an account used to break these terms.

Advertising

The service is paid for by advertising, which is why it is free. Ads sit in space reserved before they load, so the page does not jump under your finger, and no ad may imitate a site control. We do not accept advertising that has to be mistaken for something else 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, missed codes, or the consequences of someone else reading a guest mailbox. If a court finds some liability unavoidable, it is limited to what you 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 changes and the new version replaces this one from that day. In practice that means we will not notify you personally, so check this 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, not buried.
