Best Temporary Email Services in 2026 (Compared, Checked Oct 2026)

The best temporary email service depends on one question: do you need the address for the next ten minutes, the next few days, or forever? For a quick verification code, almost any receive-only service with a visible timer will do. For an inbox you want to come back to, pick a service that keeps messages for days (YOPmail, Tempmailo) or one that gives you a password (Mail.tm). For a site that rejects disposable domains, you need a real-provider address, which only a few services offer (Emailnator, SmailPro, and our own temp Gmail page).

Below is a comparison of ten services plus temp-mailx.com, built from what each service's own public pages say. We checked every page on October 29, 2026. Where a site does not state something, the table says so rather than guessing.

How we compared these services

• Source of truth is the service's own site. We read each homepage, FAQ, and API page and recorded only what the operator writes about retention, sending, API access, apps, languages, and ads or paid tiers. Nothing in the table is from memory or from third-party reviews.
• No invented test results. We did not sign up for a hundred websites with each service and tally acceptance rates, because that kind of data goes stale in a week and would not be reproducible for you. Where a service claims to bypass blocklists, we report that it claims it and nothing more.
• Same columns for everyone, including us. temp-mailx.com is in the table with its real traits, not a flattering version.
• Date-stamped. Services change plans and limits constantly. If you read this months after the date above, verify anything you depend on.

"Not stated" means the public page we read does not say. It does not mean the feature is missing; it means you should not rely on it without checking.

Service-by-service notes

temp-mailx.com. Our service issues an address the moment the page loads, with no account and no password. It is receive-only. Two countdowns are always visible: one for how long the address keeps accepting mail and one for how long stored messages are kept, and the address can be extended while it is live. Messages are rendered in a sandbox and deleted on schedule. A recovery code lets you reopen the same inbox in another browser. The temp Gmail page issues real @gmail.com dot-variant addresses from a managed pool when one is available and falls back to a random-domain address when it is not. Developers get a documented REST API. We have no apps, no sending, and no paid tier.

temp-mail.org. The largest service in the category by search presence. Its homepage renders most content client-side, so the text we could retrieve is thin: it describes a disposable address that self-destructs "after a certain time elapses" and says nothing specific about duration, API, apps, or pricing. That is a limitation of our method, not a verdict on the product.

10minutemail.com. The simplest service on the list and the one that defined the "10 minute mail" category. The address lives ten minutes, there is a "10 more minutes!" button, and the page says the service is free. It describes receiving validation emails only. The page carries a third-party VPN promotion. If you want the same ten-minute pattern with a visible retention clock as well as the address timer, see our 10 minute mail page.

Guerrilla Mail. One of the oldest services (its footer says 2006). Its FAQ states that incoming mail is kept for one hour and that addresses never expire, so you can return to the same inbox ID later and receive new mail. It is one of the few services with a Compose function. It has a long-standing public JSON API, a "scramble address" feature to hide your inbox ID, and a paid option ($9.99 per year) to route your own domain through it. It shows ads and offers 15 interface languages. The inbox-ID model means anyone who guesses your ID can read your mail, which the site itself warns about.

Maildrop. You make up any name @maildrop.cc, no signup. The homepage emphasizes spam filtering (powered by Heluna) and a GraphQL API aimed at developers testing email flows. The homepage does not state how long messages are kept; that detail lives in its "how it works" page, so check there before relying on it. Because addresses are user-chosen and not password-protected, treat any inbox as public.

Mail.tm. Different model from the rest: it creates a mailbox and a password automatically on load, so only the holder of the password can read it, and the site says the mailbox is kept until you delete it. The API is free, needs no key, is rate-limited to 8 queries per second per IP, and requires a visible link back to mail.tm if you use it. The site asks visitors to disable ad blockers, which tells you how it is funded.

Internxt Temporary Email. A free tool from a cloud-storage company, with the address and inbox expiring after three hours of inactivity. Refreshing the page gives a new address. The page says Internxt has no access to your temporary email and does not store the messages you receive. Nine interface languages. The page promotes Internxt's paid storage products, not a temp mail tier.

Emailnator. Issues real @gmail.com addresses using Gmail's dot and plus-alias behavior, with a stated 24-hour auto-delete. The site is upfront that the free inbox is public ("anyone with the address can read it") and that no temp address is guaranteed to work everywhere. Premium adds private inboxes and a phone number. There is a bulk generator for QA use.

SmailPro. The other major real-provider service, offering receive-only Gmail and Outlook addresses from managed pools. The free tier is ad-supported with limits on active inboxes and history; Premium ($2.99 per month at the time of checking) adds ad-free use, more inboxes, exact domain selection, and cloud history. Its REST API is billed separately and does not support attachments. Browser extensions for Chrome, Firefox and Edge plus an Android app. We noticed the page lists different history limits in its table and its prose, so read the current page rather than trusting any single number.

YOPmail. The long-retention outlier: messages are kept eight days, and inboxes "already exist and are never deleted," so anything@yopmail.com is always a working address. Inboxes are not password-protected, which the site acknowledges, and it offers an alias feature to hide the real inbox name. You can reply to messages and send between YOPmail addresses, but not to the outside world. Alternate domains rotate daily. Nine languages, donation-supported.

Tempmailo. A straightforward receive-only service that keeps received mail for two days and disables attachments for safety. Sending is explicitly impossible. Its API is described as coming soon. The site also offers a temp SMS tool.

Which temporary email service to pick for what

For a one-time verification code right now: any of temp-mailx.com, 10minutemail.com, Internxt, or Tempmailo. The deciding factor is whether you can see how long you have. We built two visible countdowns for exactly this reason; 10minutemail's single timer works the same way for a ten-minute job.

For an inbox you want to check again tomorrow: YOPmail (8 days) or Tempmailo (2 days) by stated retention, or Mail.tm if you want a password so nobody else can open the inbox. On our service, the retention countdown on the page tells you exactly when stored messages go, and the recovery code reopens the inbox in another browser while it is still live.

For a site that rejects disposable domains: a real-provider address. Our temp Gmail page, Emailnator and SmailPro all issue @gmail.com addresses from pools. Be honest with yourself here: a pooled Gmail address is still shared infrastructure, cannot be used to reset a password later, and is not a substitute for a real account you intend to keep. See why some sites block temporary email for how those filters work.

For developers testing sign-up flows: Mail.tm (free REST, no key), Maildrop (GraphQL), Guerrilla Mail (JSON), or our own API (REST, documented with curl, fetch and Python examples). SmailPro's API is paid per credit. If you need attachments in your tests, check each API's docs; SmailPro states it does not support them and Tempmailo disables them entirely.

For a non-English interface: Guerrilla Mail (15 languages), Internxt (9), YOPmail (9).

If you need to send mail: stop looking at temp mail. Guerrilla Mail has a Compose tab and YOPmail allows internal replies, but a disposable address that can send freely is a spam tool, and most services, including ours, refuse to offer it on purpose. If you need two-way mail without exposing your real address, you want an email alias, not temp mail.

If you need privacy from other users: Mail.tm's password model, or any service where you can see and control the deletion schedule. Avoid name-your-own-inbox services (YOPmail, Maildrop, Guerrilla Mail by inbox ID) for anything you would not pin to a notice board, because a guessable name is a public inbox. The same warning applies to every pooled Gmail service, including ours.

A last note on the "temporary email reddit" threads many people end up in: they are useful for spotting services that have gone offline or started demanding sign-ups, but they age badly and rarely cite the operator's own terms. Use them for a shortlist, then open the service's FAQ and read what it actually promises before you trust it with a code you cannot get again.
