Temp Mail for Verification Codes: How It Works and Limits

Get a code in four steps

Open the free temp mail on the homepage. An address on freedomainmail.info or freedomainmail.link is ready straight away, with no account and no password. Copy it, or choose a name of your own: 3 to 40 letters, numbers, dots, dashes or underscores.

Paste the address into the sign-up or login form and ask the site to send the code. Keep the temp mail tab open; the inbox checks for new mail every few seconds.

When the email arrives, a code found in the message is shown next to it with a Copy code button, and a verification link gets its own button. If nothing is detected, open the message and read it as usual.

Use the code quickly. Messages are deleted 10 minutes after they arrive, and many sites expire their codes even sooner.

Why a code might not arrive

The site blocks shared temp-mail domains. Many websites check new addresses against public lists of disposable domains, or look up which server receives the domain's mail, and then refuse the address or quietly drop mail to it. If nothing arrives after a couple of minutes, this is the most likely reason. Why websites block temp mail explains how the checks work.

The site is slow or limits how often it sends codes. Wait a minute before asking for a new one; requesting several in a row can lock the form, and each new code usually replaces the last.

The address has a typo. Paste it instead of typing it, and check the part after the @.

Know the limits before you use it

The inbox is public. There is no password, so anyone who knows or guesses the address can read what arrives. A long random address makes guessing harder, but it does not make the inbox private.

Nothing is kept. Mail is deleted 10 minutes after it arrives, so a password reset or a security alert sent next week will not reach you.

It only receives. You cannot reply or send from a temp mail address, and attachments are never stored, only their name, size and type.

Do not use it for banking, government services, work accounts or anything you would be upset to lose. Is temp mail safe? covers the risks in more detail.

When to use a domain you own instead

If a site rejects temp-mail domains, if you may need the account again, or if the code must stay private, use an address on a domain you own. With custom temp mail, the domain's MX record points to Free Domain Mail and every address at it receives mail in a private inbox that only your account can read. Mail is kept for 30 days.

Setup takes two DNS records: a TXT record at _maildock-verify that proves you own the domain, and an MX record pointing to mx.freedomainmail.com. It is free, and a domain you own is not on public disposable-domain lists. A site can still refuse any address it chooses, so follow each site's rules.

If you automate sign-up tests, the temp mail API waits for the email on your domain and returns the code it contains.

Common mistakes to avoid

• Closing the temp mail tab before the code arrives, then not finding the address again.
• Requesting several codes in a row, so the one you type has already been replaced by a newer one.
• Creating an account you care about with a public temp address that will not receive the password reset later.
