Free tools / Disposable email checker
Free disposable email checker
Check an e-mail address without sending anything: syntax, mail servers, disposable or temporary-mail domain (over 9,000 listed), role addresses such as info@, and likely typos of popular providers.
The result appears here as JSON.One free check per tool and IP address per day. Nothing is stored.
What you get
- Syntax and whether the domain has mail servers (MX)
- Disposable-domain and role-address flags
- A typo hint such as gmial.com
Not returned: Whether the mailbox exists (nothing is sent to the mail server).

Questions
Does it prove an address is real?
No. It catches throw-away domains and typos; only a confirmation e-mail proves a mailbox.
Is the address stored?
No. It is checked and discarded.
Can I use it in a sign-up form?
Yes, through the API or the npm and Python packages.
