Terms of Use

Last updated: 6 August 2026.

This page is written as a list of questions, because that is how people arrive at it. Something happened, or is about to, and you want to know where you stand. Using CrazyMailing means you accept the answers below.

Am I allowed to use a disposable address at all?

Here, yes. That is the whole service and there is nothing to sign.

Whether the site you are handing the address to allows it is a separate question, and one this page cannot answer for you. Plenty of them check, and being refused is a normal outcome rather than a fault on either side. What follows is about the parts we do control.

What exactly am I being given?

An inbox that receives. It costs nothing, needs no account, and lives on a domain we own and retire on our own schedule.

You get it in the state it is in on the day you use it. The behaviour written down on the about page is the whole of what is offered, and nothing outside those paragraphs has been promised to you by anybody.

Why can I not send anything?

Because a service that lets strangers send is a spam relay before the end of the week. Its domains get refused everywhere shortly after, and then the receiving half stops working too. Every free service of this kind that tried it is gone.

So sending is not a feature waiting to be built. It is the thing we do not do, on purpose, so the rest keeps running.

If a message reached you claiming to come from one of our domains, it did not. Forging a sender address is trivial and needs no access to the service that owns the name. The contact page lists what to send us if you are dealing with that.

Can I automate it?

No. There is no API, no feed and no address you can call from a script, and building one against the pages is a breach of these terms rather than a clever workaround.

The reason is arithmetic. A script opens addresses at a rate no person matches, and creation volume is exactly the signal that gets a domain flagged and added to the public lists. One automated run can end a domain's working life for everyone who was using it by hand. That is why traffic that looks scripted gets slowed first and refused after.

The same reasoning covers bulk creation done manually. The tool is not the problem, the volume is.

What counts as misuse?

Four things, and they are not subtle:

Breaking the law of the place you are sitting in. Threatening, harassing or defrauding another person. Receiving material that is illegal to hold. Opening accounts in bulk on somebody else's site against that site's rules.

A site rule and a criminal statute are not the same thing, and we have written about the distinction at length in is disposable email legal. This service is meant for getting around neither.

One more, which people rarely think of as misuse: reading other people's mail. A guest mailbox has no password, and typing addresses into the box hoping to land in a stranger's inbox is not exploration. It is the reason the privacy page tells you to treat guest mail as public.

What can you do to my mailbox?

Delete it, without warning and without telling you which one or why. Block an address, a domain or a stretch of traffic that behaves badly. Retire a mail domain so no new addresses appear on it.

These are the levers that keep the service alive under load, not punishments. In practice they land on automated abuse; a person using the site normally never notices them.

What are you promising me?

Very little, and this is the honest part.

Not uptime. The service can be slow, interrupted or down, and no announcement is owed to you when that happens.

Not delivery. A sender who refuses disposable domains simply never arrives, and we usually cannot see that they tried. A code that never came is far more often this than a bug on our side, and the practical answer is a different domain.

Not permanence. The service can change or close, and everything in every mailbox goes with it on that day.

Not fitness for anything you cannot afford to lose. Attaching one of these addresses to an account you will need to recover is a mistake with a predictable ending, and the disclaimer draws that line precisely.

What does an account change legally?

It raises the numbers, not the promises. Longer retention, ten mailboxes at once, domains that never appear on the front page, attachments, and mailboxes that strangers cannot open. Still free, and there is no paid step above it.

Your password is the whole of the protection, so anyone holding it holds every mailbox in the account. An account used to do any of the things listed under misuse gets closed.

Who pays for this?

Advertisers. That is why there is no charge and no paid tier hiding behind the free one.

Two rules bind those ads, and they are ours rather than the network's. An ad never occupies space that was not reserved before it loaded, so the page cannot jump under your finger as you reach for a button. And an ad may never dress itself up as part of the site. Advertising that only works if you mistake it for a control is not accepted here at any price.

If something goes wrong, who is liable?

Not us, as far as your local law permits. That covers lost messages, lost accounts, codes that never arrived and anything that follows from a stranger opening a guest mailbox. Where a court decides some liability cannot be waived, it is capped at the total you have paid us, which is zero.

Will these terms change?

Yes, whenever the service does. The date at the top moves and the new version takes effect that day.

You will not get a letter about it. Continuing to use the service after a change is how you accept it, so look at this page occasionally if the rules matter to you. Anything materially stricter gets stated in plain words up here rather than softened into the middle of a paragraph.
