Frequently Asked Questions
What is an MX record and why is it important?
An MX (Mail Exchange) record is a DNS record that tells email servers where to deliver emails for your domain. Without properly configured MX records, emails sent to your domain won't reach their destination. It's like having a postal address for your email.
Why do domains have multiple MX records?
Multiple MX records provide backup email delivery and load distribution. If the primary mail server (lowest priority number) is unavailable, emails automatically route to the next available server. This ensures reliable email delivery even during server maintenance or outages.
How do I fix missing or incorrect MX records?
Log into your domain registrar or DNS hosting provider and navigate to DNS settings. Add or modify MX records with your email provider's server details. For example, Google Workspace uses servers like aspmx.l.google.com with specific priority values.
