A disposable email address is a working address meant to be thrown away after a short time. Yours is at the top of this page with 30 minutes on its clock. Mail sent to it appears in the inbox right below, and you didn’t have to create an account to get it.
How a disposable email service works
An email address has two parts, and the part after the @ tells sending servers where to deliver. A disposable email service runs mail servers for a set of domains and accepts mail for almost any name on them. That is why no account is needed: the name doesn’t have to exist before a message arrives for it.
From there the message is stored and shown in the inbox, which here happens live, without a refresh. Two timers then run. The countdown beside your address tracks the address itself, and each message has its own 30-minute clock that starts when it arrives. Copy anything you need before the address runs out.
Accepting any name has a cost. No password protects a particular name, so anyone who uses the same address sees the same mail. A random name is hard to stumble on, but the inbox is never private in the way a personal mailbox is.
Disposable address or regular mailbox?
| Compare | Disposable address | Regular mailbox |
|---|---|---|
| Sign-up | None | Name, password and often a phone number |
| How long it lasts | 30 minutes on a free address | Years |
| Who can read the mail | Anyone who has the address | Only you |
| Sending and replying | No, receive only | Yes |
| File attachments | Not shown, message text only | Yes |
| Password resets later on | Not reliable | Yes |
What a disposable address is good for
- Reading one confirmation code or link from a site you are only trying out
- Getting a report or download that sits behind an email form
- Seeing what a newsletter actually sends before you subscribe with your real address
- Testing the sign-up and password emails of an app you are building, since you can make as many clean addresses as you need
How to judge a disposable email service
Many of these services look alike, so look at how they handle the risky parts. Email HTML can carry scripts and tracking images, and a careful service stops them. Here, messages open in a sandbox that blocks scripts, and remote images stay hidden until you choose to load them.
Then read what the service promises. It should say plainly how long mail is kept and that free inboxes are shared. Be wary of “100% anonymous” claims, because hiding your email address does nothing about your IP address or what you type into the site you are signing up for.
Frequently asked questions
What does disposable email mean?
It means an email address made to be used briefly and then abandoned. It receives real mail, but it isn’t linked to your name or your regular inbox. Temp mail, throwaway email and burner email are other names for the same idea.
How long do disposable emails last?
It varies by service. Here a free address lasts 30 minutes, and each message is deleted 30 minutes after it arrives. Deleted mail can’t be recovered.
Can I send email from a disposable address?
Not here, since these addresses are receive-only. If you need to send or reply, a forwarding alias service that supports replies or a second mailbox is the better tool.
Can I choose the name on my disposable address?
Yes. Press Change, pick Choose a name, and select a domain. Choose something hard to guess, because a simple name may already be in use by someone else.
Is there a version that doesn’t expire?
Pro accounts offer permanent, private addresses on Pro domains, bought in the GoMail or MailBin app. Free addresses can’t be extended.
