Fake Email Address Checker
Check whether an email address looks deliverable.
Enter an email address to check whether it could be real. We confirm the format, flag known disposable providers and check the domain can actually receive mail. We never send anything to the address, so nothing is stored and nobody gets emailed.
The Fake Email Address Checker tests whether an address looks deliverable before you rely on it. It validates the syntax of the address, then resolves the domain's MX records to confirm there is a mail server willing to receive mail for that domain. An address that is well formed but sits on a domain with no MX is almost certainly undeliverable.
What "looks deliverable" really means
No tool can guarantee a specific mailbox exists without sending a message, and responsible servers no longer reveal whether an individual address is valid. So this check is about plausibility, not certainty: correct format, a real registered domain, and a working mail exchanger. Use it to weed out typos, throwaway domains and obvious fakes in sign-up forms and contact lists, and to keep your bounce rate down.
Reading the result
- Bad syntax: the local part or domain breaks the address rules, so the address cannot be valid as written.
- No MX (and no fallback A record): the domain accepts no mail, so the address is undeliverable.
- Valid syntax and working MX: the address is plausibly deliverable, though the specific mailbox may still be empty or disabled.
Why this protects your deliverability
Sending to fake or dead addresses generates bounces and spam-trap hits, which damage your sender reputation and push your genuine mail toward spam folders. Verifying addresses at the point of entry keeps lists clean. To protect outbound mail more broadly, publish SPF, DKIM and DMARC and move DMARC to enforcement. Our enforcement guide explains how, and DMARC Engine can handle it for you. Explore the rest of our free tools for the full picture.
Frequently asked questions
Can this tool tell me for certain that a mailbox exists?
No. It confirms the address is correctly formatted and the domain has a working mail server, which means it is plausibly deliverable. Most mail servers deliberately hide whether an individual mailbox exists to prevent address harvesting, so true certainty only comes from sending a message.
What makes an email address look fake?
Common signals are invalid syntax, a domain that does not exist, a domain with no MX record, and disposable or throwaway domains used to dodge verification. Typos in well-known domains, such as a misspelled provider name, are another frequent giveaway.
Why does the domain need an MX record?
The MX record tells sending servers which host accepts mail for the domain. Without one, there is nowhere to deliver the message, so an address on an MX-less domain is effectively dead, even if the syntax is perfect.
Why bother checking addresses before sending?
Sending to invalid or fake addresses produces hard bounces and can hit spam traps, both of which harm your sender reputation. A poor reputation means more of your legitimate mail is filtered to spam, so cleaning addresses at sign-up protects your deliverability.
Does a valid address mean my email won't go to spam?
No. Deliverability also depends on your own authentication. Even to a perfectly valid address, mail can be filtered if your SPF, DKIM and DMARC are not set up correctly. Use our audit guide to check your sending domain.
Can the tool detect disposable or role-based addresses?
The core check focuses on syntax and a working mail server. Disposable domains often still have valid MX records, so a passing result does not rule out a throwaway or role address such as info@. Treat the result as a deliverability signal, not a trust score.
