Disposable Email Checker
Check whether an address uses a domain in Mailthentic's maintained disposable-provider data. The result is a domain classification, not proof that a person or mailbox is invalid.
What is a disposable email?
A disposable or temporary email uses a provider designed for short-lived addresses. It may still receive mail while active. That makes disposable a risk or policy signal, not the same thing as malformed syntax, a missing domain, or a rejected recipient.
A free provider such as Gmail or Outlook is also different. Free-provider mailboxes can be long-lived and legitimate. Use the free email checker for broader domain evidence, read how disposable detection works, or compare free and business provider signals.
How to use the result
- Apply a documented signup or lead-quality policy instead of assuming every disposable user is abusive.
- Use email confirmation when account ownership matters.
- Run full verification when syntax, MX routing, role-address, catch-all, or recipient evidence also matters.
- Recheck maintained classifications over time because providers and domains change.
Review address risk at signup
Use the asynchronous email verification API when disposable, role, DNS, and available recipient evidence must feed an application policy.
