A 10 minute mail service gives you an address that works for a short time and then vanishes. 10MinuteMail made the idea famous, but it is not the only choice. This guide lines up eight 10 minute mail alternatives next to it. Each 10 minute mail alternative gets the same seven checks, drawn only from what its own site tells visitors.
We read all nine sites this month. We do not rank them and we do not pick a winner. BillionVerify is an email verification service, and we do not run temporary inboxes. For the basics, read what temp mail is or our glossary entry on burner email.
Key facts (checked October 2026):
- 10MinuteMail states that its mail self-destructs after ten minutes, and a "Give me 10 More Minutes" link resets the countdown.
- Guerrilla Mail keeps incoming mail for 1 hour, and its about page warns that anyone holding an Inbox ID may read that mail.
- Mailinator's FAQ says mail sent to its @mailinator.com names lasts several hours, readable by anyone, with no sending.
- YOPmail's home page says messages stay eight days and leaves temporary inboxes without a password.
- Maildrop holds at most 10 messages per inbox and clears an idle one after 24 hours, per its how-it-works page.
- BillionVerify publishes a GitHub list of about 213,000 disposable domains, according to its README.
What a 10 Minute Mail Inbox Is
A timed service needs no sign-up. You open the site, copy what it shows and paste that into a form. The confirmation message lands on the same page.
10MinuteMail calls itself a secure temporary email service. Its FAQ explains that the mail and the address both self-destruct once the clock hits zero, and the address stops working a minute later. Replies and forwards work while the timer runs.
The page shows a countdown plus a button that adds time. Only you can see the mailbox, per the FAQ. The footer lists 45 languages.

What to Compare Before You Pick
Every 10 minute mail alternative differs in seven ways.
- Lifespan. It ranges from 10 minutes to several days.
- Extra time. Some services reset a timer. Others never expire the address.
- Sending. Many services only receive.
- Readers. Some mailboxes are private, while others open to anyone who has the name.
- Naming. You may get a random name or type your own.
- Money. Ads fund the free tier, and paid tiers add features.
- Language. Menus differ a lot.

Details That Do Not Fit in a Cell
- 10MinuteMail has run since 2006 and keeps mail only in memory. Its FAQ advises against it for any login you may need to recover.
- Temp-Mail sells a Premium plan with a custom domain, up to ten names at once and 100MB of storage.
- Guerrilla Mail offers a Scramble Address feature, and its mail server, Go-Guerrilla, is open source.
- EmailOnDeck warns that closing the browser or clearing cookies can end your access sooner.
- Maildrop strips every attachment and accepts messages under 500k. Heluna created it.
- YOPmail offers alias names that forward to a real YOPmail inbox.
- Mailinator targets testers. Its public tier sits beside a paid email and SMS testing platform.
- Mail.tm documents that nobody there can reset a lost mailbox password.
- Tempail adds a QR code button beside the message list.

Which Timed Inbox Fits Which Job
No service suits every job. Match these facts against your own.
Receiving One Confirmation Message
A short timer suits a single message. A countdown with a reset button is the 10MinuteMail model. Guerrilla and Tempail run for an hour. Mailinator's shared names hold mail for several hours.
Checking Mail Over Several Days
A longer-lived 10 minute mail alternative fits here. YOPmail keeps mail the longest, at eight days. Mail.tm stores it for a week and holds the mailbox until you remove it. EmailOnDeck expects free names to last most of a day.
Testing Your Own Sign-Up Flow
Developers often need many test accounts. Of the 10 minute mail alternatives above, Mailinator notes that every @mailinator.com name already exists and sells private domains on paid plans. Maildrop and Mail.tm both publish APIs, and Maildrop shows a GraphQL example.

When a Temporary Inbox Is the Wrong Tool
Not every one of these temp mail alternatives suits a login you want to keep.
- Password resets. The 10MinuteMail FAQ reports that many people lost accounts after leaving an expired address on file. EmailOnDeck gives the same warning for sites holding payment or personal details.
- Private mail. Mailinator lists "All emails are public" as a limit of its free system.
- Rejected sign-ups. Some websites check the domain against a blocklist. A refusal is a cue to use a mailbox you own.
For long-term privacy, a forwarding alias beats a timed service.

Why Websites Block These Addresses
Site owners block throwaway names for practical reasons. Fake signups, repeat free trials and contacts that never read a message all cost money, and one form can collect thousands.
The usual check is simple. The site takes the part after the @ sign and compares it with a list of known disposable providers. One service shows 11 domains on its home page, and such lists grow as new domains appear.
The free disposable email checker from BillionVerify runs that check on a single email. It compares the domain with a maintained provider list and reports whether it is disposable. The list behind it is public. The disposable library on GitHub ships Go and Rust packages plus a command-line tool, and its README describes hourly updates from nine community sources.
The BillionVerify disposable email detection flow: domain, blocklist, MX record and verdict.
Many sites also verify the email after the form is sent. A BillionVerify account gives 20 free credits on each day you use it, up to 600 a month, and they never expire. Servers sit in France (EU), and a data processing agreement can be signed. Unknown results cost nothing.
Two other tools help with related checks. The reverse email lookup reads the mail setup behind a sender. When a form asks for a phone number as well, the phone number checker shows whether it is valid and what kind of line it is.
FAQs
What is 10 Minute Mail?
10 Minute Mail is a throwaway inbox site at 10minutemail.com. It hands out an address with no sign-up, then deletes it along with its mail when time runs out. The site reports operating since 2006.
Can you extend a 10 minute mail timer?
10MinuteMail restarts the countdown when you press its extra-time button. Other services work differently. Temp-Mail and Mail.tm state that nothing needs extending, because the mailbox simply stays put.
Is there a 10 minute mail alternative that keeps messages for days?
YOPmail holds mail for 8 days, and Mail.tm stores it for 7. Both cost nothing. Guerrilla, Tempail and 10MinuteMail work in windows of an hour or less.
Can you send email from a temp mail service?
Sending support differs by service. Temp-Mail disables sending, and Mailinator only receives. YOPmail allows replies, though sending stays inside its own network.
Who can read a temporary inbox?
On public services, anyone who knows or guesses the name can read it. Mailinator and Maildrop spell this out. 10MinuteMail and Mail.tm describe their mailboxes as private to you.
Which 10 minute mail alternatives are free?
All nine services cost nothing at the basic level. Three also sell upgrades: Temp-Mail has Premium, EmailOnDeck has Pro priced in Bitcoin, and Mailinator sells paid testing plans. Guerrilla lists a yearly fee for a custom domain.
Why does a website reject a temporary email?
A website rejects a temporary email when the address matches its blocklist. That is the site owner's decision, so the normal answer is a mailbox you own.
Does BillionVerify offer a temporary email?
No. BillionVerify does not provide temporary inboxes. It offers a checking tool and a public list, so site owners can see which addresses come from throwaway services.
