MX Lookup
Find mail exchange servers and priorities for any domain.
An MX lookup reveals the mail exchange servers responsible for receiving email for a domain, along with their priority order. Enter a domain to see which servers handle its mail and in what sequence delivery is attempted. It's the first thing to check when diagnosing email delivery, migrating providers, or confirming a domain is set up to receive mail at all.
Frequently asked questions
What is an MX record?
A Mail Exchange record names the server that accepts email for a domain. A domain can list several for redundancy.
What do the priority numbers mean?
Senders try the lowest number first; higher numbers are fallbacks. Equal priorities share the load roughly evenly.
Why does a domain have no MX record?
It may not accept email, or mail is handled at the root A record (legacy behaviour). No MX usually means no dedicated mail setup.
Why do MX records point to another domain?
Many organisations use hosted email such as Google Workspace or Microsoft 365, so the MX hosts belong to the provider, not the domain itself.
Does an MX record prove email will arrive?
No. Delivery also depends on SPF, DKIM, DMARC, and the receiving server’s filtering. MX only shows where mail is routed.
