Questions About This Generator

How do I get an address here?

You already have one. An address is generated the moment the front page loads, it appears at the top of the screen, and it starts taking delivery immediately. There is no button to press first, no account to open and no confirmation step to sit through.

Copy it, paste it wherever you need it, and leave the tab open. A connection is already standing between this page and the server, and mail comes down it the moment it lands, so nothing needs refreshing and no interval needs waiting out. If you want the mechanism rather than the instructions, the assembly of the string is described step by step.

Can I choose the name myself?

Yes. Type whatever you want into the name field and it becomes the left half of the address, subject to two limits. A handful of names are reserved, abuse and postmaster among them, because mail about the domain itself has to reach a human here rather than a visitor.

Worth knowing before you do it: a name you invented is far easier for a stranger to arrive at than the one the generator produced, and a guest inbox opens for anyone who types the right address. The trade between a name you can remember and a name nobody will land on is laid out in full here.

How long does this address last?

Twenty four hours, counted from the last time you used it rather than from the moment it was made. Open the tab again on day two and the clock starts over, so an address you keep visiting keeps living.

With a free account the same address keeps going for a week measured from whenever you last signed in, and no single message inside that window survives past thirty days. Neither number is negotiable, and nothing sold above the free tier extends them, because there is nothing sold above the free tier.

What happens when I ask for a new address?

The old one is deleted at that instant, along with every message in it. There is no waiting period, no bin to fish anything out of and no way to change your mind, so read what you need before you press for a replacement.

This catches people mid-signup more than anything else. If a code has not turned up yet, wait with the tab open rather than requesting a fresh address, because the request destroys the exact inbox the code is being delivered to.

Can somebody else end up with the same address?

Yes, and the service does not treat that as a fault. Nobody owns an address here: once yours is deleted the string goes back into circulation, and the generator may hand it to somebody else weeks later. What that person gets is an empty inbox, since your messages went when the mailbox did.

What they also get is anything sent to that address from then on, which is the part that matters if you left it attached to an account somewhere. The risk is much larger for a short name you typed yourself than for a random one, and the reuse question has a guide of its own.

Can I get an address back after it is gone?

No. Expiry removes the mailbox record and its contents together, and there is no archive, no snapshot and no backup file holding a second copy. A minute afterwards there is nothing left for anyone to restore, including us.

Typing the same string into the field again gives you a fresh empty inbox on that address, not the old one. Mail that arrived while the address did not exist was refused at delivery and is not waiting anywhere.

Can I reply, or send from this address?

No to both. An address here accepts delivery and goes no further, which is a settled decision rather than an unfinished one. No reply button is waiting behind an account, and none is coming.

The reason is arithmetic. Let anonymous visitors send and the domains become a spam source within days, after which every mail provider refuses them, and the receiving half stops working along with the sending half. Blocking one direction is what keeps the other direction usable.

Is there an API?

Yes. The endpoint reference lives on the API page and the key is issued from your account with one button. Authentication is a bearer token, messages can be pushed to you down an open connection instead of polled for, and one endpoint waits for the mail to land and returns the confirmation code already pulled out of it.

Automated handout does burn working domains faster than anything else, which is why the interface draws on a set of domains kept separate from the ones this website hands out, and why a key is capped at three hundred new inboxes an hour, six hundred reads a minute and a hundred inboxes alive at once. Those inboxes expire a day after creation no matter how often they are read.

This page argued the opposite case for years. The reversal, and the reason behind every one of those numbers, is set out in its own guide.

A form refused my address. Why?

Because the site took everything to the right of the at sign, looked it up in a catalogue of domains known to be disposable, and got a hit. Your inbox is perfectly healthy and mail continues to arrive in it. One form, on one site, decided not to accept it.

Ask for a new address and you will usually get a different domain, which settles it most of the time. Writing to the list maintainers is not worth the effort, because the entry they made is factually correct.

Can I use this for a verification code?

Yes, and that is the single most common use of the service. Codes and links arrive within seconds, appear on the page by themselves, and are perfectly safe to click from here.

The line to watch is not the code, it is what the code opens. A one-time login to read an article or download a file is exactly right. An account you will still want next month is not, because the address that account resets to will have ceased to exist by then.

Who else can read this inbox?

Without an account, anybody who types the same address into this site. A guest inbox carries no password, so the address is the entire lock, and short memorable strings do get guessed by people trying likely words.

For a discount code that hardly matters. If a stranger reading the message would bother you, sign in first and use an account inbox, which answers to your account and opens for nobody else.

What do I get for registering?

Four things, and none of them costs money. Ten inboxes at once in place of your single guest one. Access to domains this website prints nowhere. Attachments that actually open. And inboxes owned by your account rather than by whoever happens to know the string.

The unpublished domains are the part that changes daily experience most. A domain that never appears on a page a scraper can read stays acceptable to signup forms far longer, which is the whole reason those domains sit behind a sign in. Running several inboxes at once also makes it practical to give every form its own address.

Can I receive attachments?

With an account, yes. A file travels with its message but is kept in a different place, and it is destroyed at the same instant the message is, so no attachment ever outlasts the mail that brought it. Anything over five megabytes is dropped while the message itself still gets through, and thirty five executable extensions are turned away at delivery without ever touching disk.

Without an account you see the text of the message and no files.

How is this free?

Advertising pays for it, and that is the whole arrangement. Nothing is sold here: no upgrade, no trial with a clock on it, and no feature disabled deliberately so that a better version exists to charge for.

Each advert sits in a slot whose height was settled before it loaded, so nothing shifts under your finger, and not one of them may be styled to look like a control belonging to this site. What that buys is a service where a confirmation link you click is always the sender's and never ours.
