A temporary email address (also called disposable email, temp mail, or a burner email) is a real inbox you can use instantly, with no sign-up, that expires after a set time and takes its messages with it. It receives mail like any address, so you can sign up and get verification codes without handing out your real email.
That's the whole idea: an address for the moment, not for life. Below is how it works, what the different names mean, and when a temporary address is the wrong choice.
How does temporary email work?
A temporary address works like any other email address, with two differences: anyone can get one in seconds, and it has an expiry date. Here is what happens when you use one:
- You get a random address. The service owns a set of domains and creates an address on one of them. No name, password, or phone number is needed.
- Senders deliver to the service's mail server. When a website emails that address, its mail server looks up the domain's MX record, which points to the temp mail provider. The provider's server accepts the message and files it under your mailbox.
- You read it in a web inbox or app. On ILoveTempMail, the inbox checks for new mail about every 15 seconds while the tab is open, so messages appear without reloading.
- The mailbox expires. After a set time, the address stops receiving mail. On ILoveTempMail, guest mailboxes (no account) expire after 5 days, and mailboxes in an account linked with the ILoveTempMail phone app last 30 days by default (Pro can extend them). The emails go sooner: on the free plan, each one is deleted 3 hours after it arrives.

Temp mail, burner, throwaway: what do the terms mean?
Several names describe the same thing, and a few similar tools work differently:
- Temporary email (temp mail): a short-lived inbox on a provider's domain that you get without signing up. "Temp mail" is the short form.
- Disposable email address: the same thing, named for what you do with it afterward. You use it, then throw it away.
- Burner email: named after the prepaid "burner" phone that people use briefly and discard. A burner email is an address for one purpose, abandoned afterward.
- Throwaway email: another word for the same idea, common on forums where people make "throwaway accounts."
- 10-minute mail: a temp inbox with a short timer, often 10 minutes. Fine for one quick code, risky if the email arrives late. See 10-minute email alternatives.
- Email alias: a permanent forwarding address. Apple's Hide My Email, for example, creates random addresses that forward mail to your personal inbox.
- Plus addressing: your own address with a tag added, like
[email protected]. Gmail delivers these tagged addresses to your normal inbox, so plus addressing helps with sorting but hides nothing.
So temp mail, disposable email, burner email, and throwaway email all mean the same thing. The real differences show up when you compare them with aliases and plus addressing.
Temporary email vs email alias vs plus addressing
The key difference is where the mail ends up. Temp mail keeps messages out of your real inbox completely, and the address disappears on its own. An alias forwards everything to you until you switch it off, which suits accounts you'll keep. For a closer look, read disposable email vs email aliases and plus addressing explained.
Why do people use a disposable email address?
Most people use temp mail to keep one-time sign-ups away from their real inbox:
- Sign-ups you won't return to: forums, downloads, coupons, Wi-Fi login pages, and one-time tools.
- Verification codes and links: confirm an address once without exposing your own. See temp mail for verification codes.
- Free trials: test a product without joining its marketing list. See temporary email for free trials.
- Less spam and breach exposure: if a site sells or leaks its list, the address that leaks is one you already threw away. More in temp mail for spam and breach protection.
- Testing: developers create many inboxes to test sign-up and password reset emails. See temporary email for developers.
When should you not use temporary email?
Disposable email is the wrong tool whenever you'll need the inbox later. Use your real address, or an alias, for:
- Banking, payments, government, healthcare, and work accounts.
- Any account you might need to recover. Password resets and security alerts go to the address on file. Once a temp mailbox expires, nobody can receive them, including you.
- Purchases with receipts, warranties, or license keys you'll want later.
- Accounts that send login codes by email. If the inbox is gone, so is your way back in.
A simple test: if losing the account would hurt, don't sign up with an address that expires.
Is temporary email safe and legal?
Using a temporary email address is legal in general. An email address isn't an identity document, and email laws mostly govern senders, not the people receiving mail. What matters is how you use it: fraud, impersonation, or making new accounts after a ban break the rules no matter which address you use. Some sites' terms also ask for a permanent address.
Safety depends on the service and on what you receive. Some temp mail sites make every inbox public, so anyone who types in your address can read your mail; public inbox risks explains why that matters. On ILoveTempMail, mail is deleted when the mailbox expires, and HTML emails are sanitized and shown in a sandbox with scripts blocked. Remote images still load, so a sender can often tell when you open a message.
No temp mail service is "100% anonymous," so don't treat any temp inbox as private storage. For the full picture, read is temporary email safe and legal? and how ILoveTempMail handles your data.
What to look for in a temporary email service
Temp mail services differ more than they look. Before you rely on one, check these points:
- Private or public inboxes. A private inbox is tied to you. A public one can be read by anyone who enters the same address.
- A clear expiry. You should know how long the address and its mail will last before you hand it out.
- Safe display of HTML mail. Scripts inside emails should be blocked.
- Code and link detection. One-tap copying prevents typos while a code's timer runs.
- More than one domain. If a site rejects one domain, you can try another.

FAQ
What is a disposable email address?

What does burner email mean?
A burner email is an address you use for one purpose and then discard, like a prepaid burner phone. In practice it means the same as temp mail or throwaway email.

Can you send email from a temporary email address?

Can websites tell you're using temp mail?
Some can. Sites compare your address against lists of known disposable domains and may reject it, as why websites block disposable emails explains. A domain you own isn't on those lists.
