See which mail server a domain uses.
Enter a domain. We pull its MX record and tell you who runs the mail and whether it can receive at all.
You get the raw priority and host list, not just a logo.
No MX record means the domain cannot receive mail.
We don't save the domain you look up.
Good to know
What an MX record lookup tells you
The MX record is the list of mail servers a domain points to, in priority order. Reading it tells you whether a domain can receive mail at all, and which provider runs it.
Use it to confirm a domain is set up for email, to identify a recipient's provider before you send, or to debug why mail to a domain keeps bouncing. We show the raw priority and host list, not just a logo.
91-93% real-world accuracy on full email verification. A live MX record proves a domain can receive mail, not that a specific mailbox exists. To verify a specific address, use the full verifier.
What is an MX record?
An MX (Mail Exchange) record is a DNS entry that points a domain to its mail servers. It includes a priority number (lower = tried first) and a hostname. Every domain that can receive email needs at least one MX record.
What does "no MX record" mean?
The domain is not set up to receive email. Any address at that domain will bounce. This is a definitive finding, not a tool error.
How do I check my domain's MX record?
Use the tool above, or run
dig MX yourdomain.com +short on macOS and Linux, or nslookup -type=MX yourdomain.com on Windows.What if the mail provider is not recognized?
Many companies self-host or use regional providers. We still show the raw hostnames in priority order so you can look them up yourself. Provider detection is a convenience, not the core result.
