Is it a disposable email? Detect temporary email addresses

Disposable email addresses are created in seconds and disappear afterwards. People use them to avoid giving their real email, but so do scammers who do not want to leave a trace. Paste an address or a domain and we check it against a public list of more than 9,000 disposable domains and against its mail servers.

How to use it

  1. Paste the email address or just the domain (the part after the @).
  2. Press “Check the email”. We only send the domain: the part before the @ never leaves your browser.
  3. Read the result: if it is disposable, whoever is writing to you can vanish whenever they want.

What it covers

Uses the public disposable-email-domains list (public domain, CC0), which is updated often, and looks up the domain's mail servers (MX) in public DNS. New services appear every day, so a very recent disposable domain may not be on it yet.

Only the domain is sent to NoCall's server, never the mailbox name. We look up public DNS and our copy of the list; we do not contact the mail server or send any message. We do not keep the domain: we only record that a check was run and its result.

Frequently asked questions

What is a disposable email?

A temporary mailbox created without signing up (Mailinator, 10 Minute Mail, Temp Mail…) that disappears shortly after. It helps you avoid giving your real email, but it also lets people write without leaving a trace.

Why does a domain I know is temporary not show up?

New disposable domains appear every day. The list is updated often, but a very recent one may not be on it yet.

Do you check whether the exact address exists?

No. We only look at the domain: whether it is disposable and whether it can receive email. We do not contact the mail server, so nobody is tipped off that the address is being checked.

Is a Gmail address disposable?

No. Gmail, Outlook and Yahoo are real free providers. But anyone can open an account with them, so a bank or a company will never write to you from a free address.
