Email address checker: can this address receive email?
Before you write to an address or trust one, check it here. We look at how it’s written and at its domain: whether it exists, whether it receives email and what kind of address it is. We can’t tell whether the mailbox itself exists, because we never contact its mail server, and we don’t store the address.
How to use it
- Type or paste the email address you want to check.
- Press “Check the address”. We check how it’s written and look up its domain in public DNS.
- Read the result and the signals. If we suggest another domain (for example gmail.com instead of gmial.com), confirm the address with whoever gave it to you.
What each result means
- This isn’t a valid email address
- It doesn’t have the shape of an address: the @ or the domain is missing, or it has characters an address can’t use.
- The domain of this address doesn’t exist
- Nobody can receive email at it. If someone gave you this address, they may have mistyped it.
- The domain doesn’t receive email
- It exists, but it has no mail servers or it states that it accepts no email. A message to this address won’t arrive.
- The domain receives email
- The address is well written and its domain has mail servers. We can’t confirm that this particular mailbox exists, only that the domain can receive email.
What each signal means
- The address isn’t written the way an email address has to be.
- The domain doesn’t exist in DNS.
- The domain states that it receives no email (“null MX”).
- The domain has no mail servers.
- The domain has no MX records, so email goes to its own address. It works, but it’s unusual.
- It’s a disposable email service: these addresses last minutes or hours and are often used to sign up without giving a real address.
- It’s a role address (info@, support@, noreply@…) that belongs to a team or a service, not to one person.
- It’s a free email service (Gmail, Outlook, Yahoo…). Anyone can open an account, so a bank or a company won’t usually write to you from one.
- The domain looks a lot like a well-known provider’s, so the address may have been mistyped.

Which countries it covers
Works with addresses from any country, including domains with accents or in other alphabets. Disposable domains come from an open list of thousands of throwaway email services; free email domains cover the big international and national providers.
The address is sent to NoCall’s server only to look up its domain in public DNS, and it isn’t stored. We never contact its mail server.
Frequently asked questions
Can you tell whether the mailbox exists?
No, and no service can do it reliably: the only way is to ask the domain’s mail server, many servers say yes to every address, and repeated probes end up blocked. We check everything that can be known without contacting it.
What is a disposable address?
An inbox that works for minutes or hours, used to sign up somewhere without giving a real address. If a customer or a contact gives you one, you won’t be able to reach them later.
What is a role address?
One that belongs to a function rather than a person: info@, support@, sales@, noreply@. Many people may read it, or nobody at all in the case of noreply@.
Is the address I check stored?
No. It’s used once to look up its domain in DNS and isn’t stored anywhere. We only note that a check was made and its kind of result (for example, “the domain receives email”), without the address.
