The DNS record used for email servers is the MX record (Mail Exchange record). It tells the internet which mail server should receive email for a domain.

Quick Scoop

  • MX record = routes email to the correct mail server.
  • Lower MX priority numbers are tried first when multiple mail servers exist.
  • TXT records are also common for email, but mainly for authentication like SPF, DKIM, and DMARC, not delivery routing.

If you want, I can also show a simple example of an MX record.
