MX Record Lookup
Check the mail servers for any domain — MX records with priorities and TTLs — instantly and entirely in your browser.
How to read MX records
Enter a domain and this tool returns its MX records — the servers that accept email for the domain — each with a priority and TTL. Lower priority numbers are tried first. Switch to the Health check tab to also confirm that every MX target resolves and that SPF and DMARC are configured.
- See all mail servers and their priorities at a glance.
- Confirm MX targets resolve to real A/AAAA records (no dangling MX).
- Cross-check SPF and DMARC with the Health check.
Frequently asked questions
What is an MX record?
An MX (Mail Exchange) record tells the internet which servers accept email for a domain. Each MX record has a priority — lower numbers are tried first.
Why does my domain have no MX records?
A domain used only for a website may have no MX records, which is fine. But if you expect to receive email and there are no MX records, mail cannot be delivered.
What priority should my MX records be?
Lower numbers have higher priority. A common setup is a primary server at priority 10 and a backup at 20. Every MX target should resolve to a valid A or AAAA record.
