An MX record specifies the mail servers responsible for receiving email for a domain. Each record includes a priority value, where lower numbers have higher priority.
Why it matters: Incorrect MX records can cause email delivery failures.
Quick tips:
- Use multiple MX records for redundancy.
- Ensure SPF, DKIM, and DMARC are set in TXT records.
