Best Temporary Email Services: 7 Free Options Compared

How we chose

Seven services were picked because they are still running, still free to use without registration, and each does a different job. Prices, inbox lifetimes, and limits were taken from each vendor's own site, or from a vendor page that states the figure in writing, and checked on 13 November 2026. Mailinator's pricing was read directly on its pricing page. The other vendors' pricing pages did not load in full during this check because the page fetcher was rate-limited, so their prices were cross-checked against two or more independent sources quoting the vendor's own page — confirm the current figure on the vendor's site before you pay. No accounts were created and no messages were sent, so nothing here is a test result. Ranking is by use case: the quickest signup first, the developer tool later, because a temporary inbox is a tool you pick for a job, not a product you rank by features alone.

A temporary email service gives you a throwaway address for a signup, a download, or a trial, so your real inbox stays free of marketing mail and your address stays out of breach databases. A temporary email address is a disposable address that expires after a set time, or that you abandon after one use.

1. Temp-Mail.org: best for quick signups with no registration

Temp-Mail.org is the simplest service in this list to use. You open the site and an address is already waiting, with no registration and no password. The inbox refreshes in real time, you can change or delete the address, and there are multiple domain options. Free messages are kept for up to 1 to 2 hours.

The free plan is supported by ads and is receive-only: you cannot send email from a Temp-Mail.org address. Premium costs $10 a month, or $60 a year, which works out at $5 a month, and adds custom domains, dedicated premium domains, up to 10 mailboxes at the same time, message storage for one month, and an ad-free experience. Premium on the web does not carry over to the mobile apps, which sell their own subscriptions.

Temp-Mail.org suits a quick signup where you need a code in the next few minutes. Skip it if you need to reply to the sender, or if you need the message to still be there tomorrow — the free inbox will not keep it.

2. Guerrilla Mail: best for sending a reply with an attachment

Guerrilla Mail is the oldest service in this list, running since 2006, and it is the only one here that lets you send email as well as receive it. You can compose a message from your disposable address and attach files up to 150 MB. It also offers a Scramble Address control, custom address names, and an API.

The trade-off is privacy. Guerrilla Mail inboxes are public: anyone who knows your address can read your messages. Messages are cleared about an hour after they arrive, although you can stretch that window. The service is free to receive and send from the minted address. An own-domain option costs $9.99 a year, which gives you email to a domain you already own, readable only by you.

Guerrilla Mail suits a signup where you need to reply, or a download where you need to send a file back. Skip it for anything you would not want a stranger to read, and skip it if the site you are signing up for blocks its domains — its addresses are widely known and widely blocked.

3. 10 Minute Mail: best for a single confirmation code

10 Minute Mail does exactly what its name says. You open the site, an address is minted, and a visible countdown starts at ten minutes. You can extend the timer in ten-minute steps while you wait for a slow sender. There is no account, no password, and no premium tier to upsell you.

The short timer is both the point and the limit. A confirmation code that arrives in two minutes is perfect for this service. A code that arrives in twenty minutes is not, unless you remember to extend the timer. The service is free, it receives email from any sender, and the inbox is private rather than publicly guessable.

10 Minute Mail suits a single verification link and nothing else. Skip it if you need to come back to the inbox later, or if you need to send anything.

4. Mailinator: best for developers testing signups

Mailinator works differently from the other services here. Any address at its domains instantly becomes a readable public inbox, with no signup and no setup. That makes it a test fixture, not a private address: anyone who types the same address can read the same messages. The free public inboxes are free, and a Verified Pro plan is free after verification for a single user, with a private domain and API access.

The paid product is for QA teams. Business costs $79 a month when billed yearly, or $99 a month billed monthly, and includes 1 private domain, 5 team seats, and 100,000 emails a month. Business Plus costs $159 a month billed yearly, with 3 private domains, 10 seats, and 300,000 emails a month. Enterprise starts at $699 a month with custom limits. Paid plans add private domains, an API, webhooks, routing rules, and SMS testing.

Mailinator suits a developer or QA engineer testing signup, OTP, or password-reset flows in automated tests. Skip it for personal signups: the public inboxes are readable by anyone, and a password reset in one is not private.

5. YOPmail: best for a free inbox that lasts 8 days

YOPmail has run since 2004, which makes it one of the oldest disposable email services still operating. You invent a username, add the yopmail.com domain, and the address works. There is no registration, no password, and no personal information to give. Messages are kept for 8 days and then deleted automatically, which is far longer than most services in this list.

YOPmail also adds a new alternate domain every day, which helps when sites block the main domain. You can reply to messages, but only to other YOPmail users. The service is entirely free, funded by donations, with no paid tier advertised.

The weakness is the same as Mailinator's: YOPmail inboxes have no password protection. Anyone who knows or guesses the inbox name can read the messages, so do not use an address name that reveals your identity or business. YOPmail suits a signup where you need the inbox to still be there in a few days. Skip it for anything sensitive, and skip it if the site blocks disposable domains — YOPmail is on many blocklists.

6. Temp-Mail.io: best for a cheap premium tier with apps

Temp-Mail.io is a separate service from Temp-Mail.org, with a similar name and a different product. It gives you a free disposable address on the web, with browser extensions and iOS and Android apps, and it supports multiple addresses at the same time, message forwarding, and custom addresses on the paid tier.

The free tier is ad-supported and receive-only. Premium costs $2.99 a month and adds an ad-free experience, more domains, and the paid features. That is the cheapest premium tier in this list, well below Temp-Mail.org's $10 a month.

Temp-Mail.io suits a user who wants the same throwaway inbox on their phone and their browser, and who is willing to pay a small amount to remove ads. Skip it if you need to send email — the free tier does not send — or if you need the longest inbox life, which YOPmail beats at 8 days.

7. Maildrop: best for a simple public inbox with no signup

Maildrop is a plain public inbox. You pick a name, add the maildrop.cc domain, and any mail sent to that address is readable on the site. There is no registration, no password, and no paid tier. It is free, and it does one job with no extra features.

Maildrop's simplicity is its limit. Inboxes are public, messages are short-lived, and there is no sending, no apps, and no custom domain. It suits a quick test where you need to see whether a form sends mail at all, or a signup you will never return to. Skip it if you need privacy, a longer inbox life, or any feature beyond reading a message.

How to choose

A worked cost calculation

If you pay for a premium tier for a year, the totals are small but different. Temp-Mail.org Premium at $60 a year costs $5 a month. Temp-Mail.io Premium at $2.99 a month costs $35.88 a year. Mailinator Business at $79 a month billed yearly costs $948 a year. Guerrilla Mail's own-domain option at $9.99 a year is the cheapest paid option here, but it is a different product: it gives you a private domain, not a premium inbox.

For most personal use, the free tier is enough. Pay only if you need the specific paid feature — custom domains, longer storage, or an API — and check whether the free tier of another service already gives you that feature for nothing.

Who should not use a temporary email

• Anyone signing up for banking, finance, or government services. Those accounts need a real, recoverable address.
• Anyone who needs password recovery. A temporary address that expires locks you out of the account.
• Anyone receiving medical, legal, or work mail. Temporary inboxes are public or short-lived, and neither is safe for sensitive mail.
• Anyone who needs to prove they own the address later. A throwaway address cannot prove ownership once it is gone.

Common mistakes with temporary email

• Using a public inbox for a password reset. Anyone who guesses the address can read the reset link. Use a real address for resets.
• Letting the timer expire before the code arrives. Extend the timer at 10 Minute Mail, or pick a service with a longer inbox life.
• Reusing the same throwaway address everywhere. One address tied to many accounts is no longer throwaway. Mint a fresh one for each signup.
• Expecting the address to work everywhere. Many sites block disposable domains. If a signup rejects your address, try another service or use a real address.
