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. What to gather up and send us in that situation is set out on the contact page, and the short version is the full headers as text.

Can I automate it?

No. Nothing here is published as an API, a feed, or an endpoint meant to be called from a script, and assembling one by driving the pages yourself breaches these terms rather than cleverly sidestepping them.

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, with no warning beforehand and no explanation of which mailbox or on what grounds afterwards. Shut out a single address, a whole domain, or a band of traffic that is misbehaving. Withdraw a mail domain from service, after which it issues nothing new.

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. Where the sending side declines to mail disposable domains, nothing ever reaches us, and in most cases we cannot even tell that an attempt was made. A confirmation code that failed to show up is this far more often than it is a fault at our end, and the useful response is to try another 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.

Keeping your sign in details to yourself is your responsibility, and whoever ends up holding them reaches every mailbox the account owns. Turn an account to any of the purposes listed under misuse above and it 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, to whatever extent the law where you live allows that. Messages lost, accounts lost, codes that never turned up, and every consequence flowing from somebody else opening a guest mailbox all sit inside that. Should a court hold that a particular liability cannot be signed away, the ceiling on it is the sum total you have paid us, and that sum is zero.

Will these terms change?

Yes, whenever the service itself does. The date printed at the head of this page moves, and the revised version applies from that day onward.

No letter will arrive telling you so. Carrying on using the service once something has changed is what counts as accepting it, which is a reason to glance back here now and then if the rules bear on what you are doing. Anything that tightens matters in a real way gets said in plain language up here, not buried halfway through some paragraph further down.
