MX Lookup

See which mail servers receive email for a domain, sorted by priority (lowest number wins).

About MX records

MX (Mail Exchange) records point a domain’s email to the servers that accept it. Lower priority numbers are preferred; higher numbers act as backups. No MX record means the domain doesn’t receive mail at its apex.

Frequently asked questions

▸ What does MX priority mean?

Lower numbers are tried first. If the primary is unreachable, senders fall back to higher-numbered MX servers.

▸ No MX record — can I still receive mail?

No. A domain with no MX record can't receive email. Add at least one MX record pointing at your mail host.
