MX records are the DNS entries that route email to the right servers. Looking them up tells you whether a domain can receive mail at all, and which provider (Google, Microsoft, etc.) runs it.
This free MX lookup queries DNS live from your browser and lists the mail servers in priority order — handy for diagnosing delivery issues or vetting a domain before you reach out.
A domain having MX records means it can receive email — but it doesn't mean a specific address is real. Catch-all domains accept everything and tell you nothing.
When you need certainty about an individual address, Emailchaser's free email verifier checks deliverability mailbox by mailbox.
What is an MX record?
An MX (Mail Exchange) record is a DNS record that tells the internet which servers handle email for a domain, and in what priority order. If a domain has no MX records, it generally can't receive email.
How do I check a domain's MX records?
Enter the domain above and click look up. The tool queries DNS live and lists the mail servers with their priorities, lowest number first. It's the quickest way to see who hosts a domain's email (Google, Microsoft, etc.).
Why does MX matter for cold email?
Before sending to a domain, MX records confirm it can actually receive mail. They also reveal the email provider, which helps you tailor sending. A missing MX is a red flag that the address will bounce.
Is the MX lookup free?
Yes — it's free and needs no signup. The lookup runs from your browser using a public DNS service.
