Disclaimer
Every complaint that reaches us about disposable email is one of five. Here they are, with what this service can and cannot do about each, so that nothing on this site is promising you something it has no way to deliver.
"The site rejected my address"
This is the most common one by a distance, and it is not a fault.
Thousands of sites check the domain of an address against public lists of disposable providers, and those lists are updated constantly by people whose whole purpose is finding domains like ours. Any domain that becomes popular gets listed eventually. A rejection means the check worked, not that anything here broke.
What helps: a different domain from the list on the front page, or an account, which unlocks domains that are never printed on a public page and therefore reach the lists later. What does not help: waiting, refreshing, or writing to us, because we cannot alter another company's blocklist and would not be told if we could.
"The message never arrived"
The other half of the same coin, and harder to see, because nothing visible happens.
A sender who refuses disposable domains usually declines to deliver quietly. No bounce comes back to them, no record appears here, and the code you are waiting for simply never exists. From your side it is indistinguishable from a slow service, which is why people refresh for ten minutes before giving up.
We cannot promise that a given site will send to a given address, and no service of this kind can. If a message has not come in a couple of minutes, take a different address rather than a longer wait.
"Somebody else read my mail"
If it was a guest mailbox, that is possible, and it follows from the design rather than from a failure.
Guest mailboxes have no password. The address is the only thing between the mail inside and anybody else, and short memorable addresses do get guessed by people typing likely words into our own front page. That is a reasonable trade for a discount code and a bad one for anything you would mind a stranger reading.
An account closes that particular hole: mailboxes belonging to an account are private to it. What an account does not do is turn this into a secure channel. It remains a free service paid for by advertising, and it has never been offered as anything else.
"I lost an account because the address expired"
This is the expensive one, and it is the reason this page exists.
Ask one question before you use an address from here: might I ever need this to get back into something? A yes or a maybe means use your real mailbox. That rules out banking and payments, government and tax portals, work, deliveries, domain registration, cloud storage, and anything holding money or files you would miss.
A recovery address has to outlive the account it protects. Every address issued here is built to expire, which is the opposite requirement, and no support request anywhere recovers an account whose recovery address has ceased to exist. There is nothing we can do at that point either: the mailbox is not disabled or archived, it is gone.
"Something in my inbox was a scam"
Probably, and we did not put it there.
Messages displayed here were written by whoever sent them. We do not read them, review them, endorse them, or vouch for any link, offer or attachment inside. Scripts and remote content are stripped before anything is shown, which removes the most common tracking and the most common attacks, but stripping does not make a hostile attachment safe or a fraudulent link honest. Treat mail arriving at a throwaway address with the suspicion it deserves: nobody who knows you sent it.
About the rest of this site
The guides here describe how detection works, how blocklists are assembled and how other companies handle disposable addresses. Those companies change their rules without announcements, so a description accurate on the day it was written can quietly go stale. Check the current behaviour before you rely on any of it, and tell us through the contact page when something has drifted.
It is general information, not advice about your situation, and certainly not legal advice. Where the consequences are real, ask somebody qualified where you live rather than a free mail service.
And the service itself
Free, offered without warranty of any kind, and liable to be interrupted, changed or shut down without notice. Whatever sits in a mailbox at that moment goes with it. The terms of use set out the rest.

Burner Email Addresses
People want four different things when they ask for a burner email. Which one fits your situation, and where a burner is the wrong answer.
Temporary Email and Permanent Email Are Not Rivals
A permanent address collects senders for years and cannot be taken back. A temporary one ends the same day. The difference is not privacy talk, it is who holds the string afterwards.
