Frequently Asked Questions
ā What are MX records?
MX (Mail Exchange) records specify which mail servers accept email for a domain and their priority order.
ā What does MX priority mean?
Lower priority numbers are preferred. If the primary server (priority 10) is down, email goes to the backup (priority 20).
ā Why are MX records important for email?
Without correct MX records, email can't be delivered to your domain. They're essential for any domain receiving email.
