MX Record Lookup Tool
Check mail exchange records for any domain to verify email delivery capability.
What Are MX Records?
MX (Mail Exchange) records are DNS entries that specify which mail servers are responsible for receiving email on behalf of a domain. Each MX record has a priority value — lower numbers indicate higher preference. Without valid MX records, a domain cannot receive email.
Why Check MX Records?
MX record verification is essential before sending important emails. It confirms that the recipient's domain can actually receive mail, prevents delivery to non-existent domains, and helps identify potential deliverability issues early in your email validation workflow.
