The well-known options
10 Minute Mail popularized the format: a random address that lasts about ten minutes with a timer you can extend. Guerrilla Mail keeps mail for roughly an hour and lets you send as well as receive. YOPmail uses predictable, guessable inboxes that persist for days, which is convenient but far from private.
Mailinator is aimed at teams and testing, with public inboxes anyone can open by name. Each trades privacy, lifetime, and convenience differently — there is no single best one, only the best fit for a given task.
- 10 Minute Mail — random address, roughly ten minutes, extendable. The reference implementation of the format and the name most people search.
- Guerrilla Mail — about an hour of retention and it can send as well as receive, which is unusual in this category and occasionally essential.
- YOPmail — fixed, predictable addresses that persist for days. Convenient because you can come back to the same inbox; not private, because so can anyone else.
- Mailinator — public inboxes addressed by name, built for teams and QA. Ideal for shared testing, unsuitable for anything you would not publish.
- This service — random address, hard five-minute timer, no signup, inbox on the page. The shortest-lived of the group by design.
Which is the best temp mail service?
The honest answer is that the question has no single winner, because the services differ mainly in retention and that is a trade-off rather than a feature. A longer lifetime buys you time to act and costs you exposure: a public address with no password stays readable for exactly as long as it exists.
So the useful version of the question is how long the mail you are expecting will take to arrive, and whether you will ever need it again. Automated verification codes arrive in seconds, which makes the shortest-lived option the best choice — nothing lingers afterwards. A link you must open in an hour makes the shortest option the worst one. Neither answer is about quality.
One thing no service in this list does better than another is getting past a block. Sites filter these providers by domain, so if a signup rejects one disposable address, switching brands sometimes helps and often does not. When a site is strict, a real mailbox is the only route.
Where this inbox fits
Temporary Email is the short-and-clean option: a random address, no signup, and a hard five-minute timer. That is long enough for most verification codes and short enough that leftover mail never piles up on a public address.
If you need mail to sit for an hour, a longer-lived service is a better match. If you just need a code now and want it gone afterwards, the inbox on this page is the simplest path — copy the address, grab the code, let it expire.
Choosing the right one
For a one-time code: any short-lived service works, including this one. For a link you must click an hour later: pick a service with a longer lifetime. For shared team testing: a named public-inbox tool like Mailinator is designed for that.
Whatever you choose, the same limits apply across the category: some sites block disposable domains, none of these are private mailboxes, and none should hold anything you need to keep.
When the alternative is not a temp mail service at all
Sometimes the right answer is outside the category. If you want to keep marketing mail out of your main inbox but still be reachable next year, an email alias — the addresses Apple's Hide My Email, Firefox Relay, or a self-hosted catch-all provide — is a better fit than anything here. Aliases forward to your real mailbox, so they last indefinitely, can be switched off per sender, and still let a password reset reach you.
For automated testing the right tool is a mailbox service with an API and real retention rather than a browser widget. And for the awkward middle case — an account you want at arm's length but must keep access to — a second free mailbox from a normal provider beats every disposable option, because the whole point is that it does not expire.
Disposable inboxes win in exactly one situation: the mail has no value to you ten minutes from now. That is a narrow window, and recognising when you are outside it prevents most of the problems people blame on temp mail.
