How we spot a disposable address

Throwaway services reuse a small set of domains and mail servers, which makes them recognizable.

  1. Paste the address

    From a sign-up form, a marketplace chat, or an email header.

  2. Match the domain

    We compare it and its parent domain against known temporary inbox services.

  3. Read the verdict

    Disposable addresses are postmarked “Risky” with the reason spelled out.

Disposable email questions

Is a disposable address always a scam?

No. Many people use them to avoid spam. They are a reason for caution when money or trust is involved, not proof of bad intent.

Can a new throwaway service slip through?

Yes. New services appear constantly. If the check says “Custom domain” for an odd-looking domain, treat it carefully.

What about Gmail aliases with a plus sign?

Those reach a real Gmail inbox. We note the tag but do not treat it as disposable.
