Look up MX records
See which servers receive mail for a domain, in the order senders try them, and the mail service behind each one. No account.
Receiving is half of it. Is your sending set up?
Email Digit publishes and maintains the records that decide whether your mail arrives: SPF, DKIM keys we rotate for you, and a DMARC policy we move from none to reject when your reports say it is safe.
What MX records do
MX records tell the rest of the internet which servers receive mail for your domain, and in what order to try them. They are separate from the records that decide who may send as you.
How the service is named
Each host is matched against the names large mail services use for their receiving servers. A host we do not recognise is shown as self hosted or other, which is often right and sometimes a smaller service.
What the lookup checks
Records in priority order, a null MX and whether it is mixed with others, no MX at all, hosts that are IP addresses, and hosts that do not resolve.
MX record questions
What does the priority number mean?
Senders try the lowest number first and move to higher numbers only when it does not answer. Two records with the same number share the load.
What happens with no MX record?
Senders fall back to the domain's own address, which is usually a web server that does not accept mail. Replies, bounces and DMARC reports sent to the domain are then lost.
What is a null MX?
A single MX record pointing at a dot, defined in RFC 7505. It says the domain accepts no mail at all, so senders give up at once instead of retrying for days.
Do MX records affect sending?
Not directly: they decide where mail to you is delivered. But a domain that cannot receive mail loses replies and bounces, and some receivers distrust mail from it.
