Why Do I Need an MX Record?
MX records play a critical role in email delivery by directing messages to the correct servers, prioritizing delivery order, and providing redundancy. A properly configured MX record helps ensure your email is delivered reliably and efficiently.
MX records also affect inbound email delivery. If an MX record is missing or misconfigured, you won't receive email sent to you, which negatively impacts your business and its reputation.
Why MX Records Are Important
-
Reliable Email Delivery: Ensures emails reach the correct mail servers and aren't lost.
-
Redundancy and Failover: Backup servers can receive mail if the primary server is down.
-
Load Balancing: When multiple servers share the same priority, email can be distributed across them.
