What is an MX record? A Plain-English Guide
An MX (Mail Exchange) record tells other servers where to deliver mail for your domain. Misconfigured MX records break receiving and can affect how your domain is trusted.
Why it matters for deliverability
Understanding an MX record is part of how mail finds your domain. Get it right and more of your mail reaches the inbox; get it wrong and even legitimate mail can be filtered.
