What Is a Burner Email?

A burner email is a temporary address you use instead of your main inbox. It is useful for signups, trials, and one-off messages. nullmail creates a random receive-only inbox with no account and no password. The inbox expires, and messages are hard-deleted at expiry.

What Is a Burner Email?

A burner email is a temporary email address that stands in for your regular inbox. It is also called a disposable email or temp mail. The point is simple: give a site an address that can receive a confirmation link without exposing the address you use for work, banking, or family. You do not need to make an account to read it, and you do not need to hand over a phone number or password. nullmail follows that model. The address is random, the inbox receives real email, and the whole thing is meant to be short-lived.

What Do People Use a Burner Email For?

A burner email is most often used when a website asks for an address but you do not want to share your real one. You might need to read a verification link, download a file, or claim a small discount. Signing up for a trial is a common reason, because it lets you test a product without adding your main inbox to a mailing list. Forums, comment sections, and one-time downloads are other times a temporary address can help. You can also use one to separate low-priority messages from the mail you actually care about. With nullmail, you open the site and get a random address straight away. There is no account to create and no password to remember. The inbox is receive-only, so it works for incoming mail such as confirmations and links. It is not meant for sending replies or for long-term contact.

How Long Does a nullmail Burner Email Last?

nullmail inboxes live about 60 minutes by default. After that, the inbox expires. Messages in it are hard-deleted at expiry, so you should not treat a burner email as storage. If you need to keep a confirmation code, copy it somewhere safe before the timer runs out. If you only need to click a verification link, that is usually enough time. The short life is part of what makes the service useful: there is less leftover data tied to an address you do not plan to keep.

Can You Send Email From a nullmail Burner Inbox?

No. nullmail inboxes are receive-only. You can get incoming messages such as signup confirmations, password reset links, or download links, but you cannot send a reply from the address. That is normal for most temporary email services, and it keeps the inbox focused on one job. If a form asks you to reply to an email, a burner inbox from nullmail will not work for that step. For one-way verification, it is a simple way to keep your main address out of a signup flow.

Is a burner email the same as a disposable email?

Yes. A burner email is another name for a disposable or temporary email address. It receives mail for a short time, then expires.

Do I need an account to use a nullmail burner email?

No. You open nullmail and get a random address. There is no signup, no password, and no personal data required.

Can I use a nullmail burner email to send messages?

No. nullmail is receive-only. You can receive email, including verification links, but you cannot send or reply from the inbox.

What happens to messages when the inbox expires?

The inbox expires after about 60 minutes by default. At expiry, messages are hard-deleted. Copy anything you need before then.

Can I reuse a nullmail burner email later?

No. The address is temporary and tied to the inbox session. Once it expires, the inbox and its messages are gone. You get a new random address the next time you open nullmail.

Is a burner email good for banking or important accounts?

No. Because the inbox expires and messages are hard-deleted, a burner email is a poor fit for accounts you need to recover later. Use it for signups, trials, downloads, and other one-time messages.
