Waiting for new mail…
Emails sent to your address appear here automatically. Usually within a few seconds.Updated · Volt Ghost team
In short. Yes: Volt Ghost gives you a free 24 hour email address with no sign-up. The inbox is created instantly, stays open for one day from that moment, and is then deleted. Most same-day codes and links never need the optional extension. If a message might arrive later in the week, you can lengthen the same inbox once, free, up to 7 days. Recovery works only while the inbox is still active.
What a 24 hour email is
People searching for a 24 hour email want a working address that survives a whole day, then disappears. They are usually trying to avoid two failures: a ten-minute inbox that dies before a delayed code arrives, and a permanent mailbox that will keep collecting marketing after the sign-up is done.
Volt Ghost is built around that day-long window. Open this page and you already have a private, receive-only inbox. There is no registration, no password, and no advertisement in the inbox. When the 24 hours are over, the address and its messages are removed automatically.
When a single day is the right length
A day is the sweet spot for tasks that finish today but might not finish in the next few minutes:
- A sign-up whose confirmation is slow. Busy services, weekend queues and second-step reviews often take longer than a short timer allows, but the message still arrives the same day.
- Two messages, not one. A welcome note now and a “confirm this device” or coupon mail a few hours later still fit inside a 24-hour window.
- A one-day trip or shift. Cafe Wi-Fi portals, a same-day download, or a newsletter you only wanted to peek at, covered on the newsletter use page.
- Manual checks of an app you are building. A developer clicking through a staging sign-up can keep the same inbox open across lunch and a late deploy. For a throwaway test user, see disposable email for app testing. For a checklist of the mail your product sends, see temp email for testing.
A classic 10 minute mail inbox is enough only when the message is already on its way and you are watching the page. A week-long inbox is the better fit when a free trial or an event join link might land days later — that is what the optional extension, explained on the 7-day temp mail page, is for.
How the 24-hour clock runs
The countdown starts when the address is created, not when the first message arrives. Leave the tab open, come back later in the same browser, or open the recovery link elsewhere: the remaining time is the same, because it is tied to the inbox, not to a tab.
Cleanup runs about once an hour, so an inbox may linger a short while after the timer hits zero before the stored mail is actually wiped. Do not rely on that grace period. If you still need the address, lengthen it while the timer shows time left.
The optional extension is counted from the moment you press the button, and you get one per inbox. Choosing +24 hours, +3 days or +7 days replaces the original expiry; mail already in the inbox is kept until the new time. There is no second extension, and no paid plan that buys more.
A simple same-day path
- Copy the address in the card above. A realistic-looking name is the default; switch to a random string if you prefer.
- Paste it into the form that asked for an email. Watch this page — new mail appears within a few seconds, and 4–8 digit codes get a copy button.
- If you might close the tab, copy the recovery link first. It reopens the same inbox on another phone or laptop, but only until the inbox ends. Details are on the recovery page.
- When you are finished, you can leave. There is nothing to cancel. If you are done early, press New address and stop using the old one; it still expires on schedule and is not handed to anyone else in the meantime.
When you should lengthen the inbox, and when you should not
Lengthen it if you already know a later message matters: a trial reminder, a waitlist, a shipping update, or a webinar link that will be sent the day before the event. Do that early in the 24 hours so the new window is as long as you intended.
Do not lengthen it, and do not use this address at all, for anything you must still be able to open next month. Banking, work, government, health, paid tickets and accounts you will need a password reset for belong in a lasting mailbox or an email alias. The reasons are spelled out in when not to use temp mail.
Some sites refuse known disposable domains, including mailghost.cyou and mailghost.cfd, which are listed on purpose. You can confirm a domain with the disposable email checker. If a form rejects the address, cycling through other throwaway services is usually a waste of time; the practical next steps are in why sites reject temp email.
Limits of a day-long inbox
- The address can only receive mail. It cannot send or reply, so a process that asks you to write back will fail.
- File attachments are not stored. If the useful part of a message is a file, this inbox will not keep it.
- Messages larger than about 2 MB are rejected, and very long bodies are cut short.
- Anyone who has the recovery link can read the inbox until it expires, so treat that link like a password and do not post it in public.
- Analytics on this site run only after you accept the cookie banner; they are off by default.
If you arrived here from a 10-minute mail habit, the longer default is the whole point of this page. If you already know you need a week, skip ahead to temp mail for 7 days and extend once. New to disposable addresses in general? Start with what temp mail is.
Questions
What is a 24 hour email?
It is a temporary address that receives mail for one day and is then deleted. On Volt Ghost that day-long lifetime is the default, not an upgrade. You get the address in one click, with no account.
Is a 24 hour email free?
Yes. There is no paid plan and nothing to register. Generate a new address whenever you need one.
What happens when the 24 hours end?
The address stops accepting mail and stored messages are deleted by an hourly cleanup job. The recovery link stops working too. Nothing from that inbox is kept after that.
Can I keep a 24 hour email for longer?
Once, yes. You can lengthen the same inbox, free, by 24 hours, 3 days or 7 days. That can be done only once per address. After the new expiry, the inbox cannot be restored.
Is 24 hours enough for a verification code?
Usually yes. Most confirmation messages arrive within seconds or a few minutes. A full day also covers a delayed sender or a second message later the same day. If you expect mail several days later, lengthen the inbox before it ends.
How do I reopen the inbox later today?
Copy the recovery link and open it on any device while the inbox is still active. After it expires, the address and its mail cannot be restored.
