Mail Exchange (MX) records are DNS records that are required for your address to send emails.
An MX record is used in simple DNS terms to tell the world which mail servers accept your domain's incoming mail and to which emails sent to your domain should be routed. You will not receive emails if your MX records are not pointed to the correct spot.
H2: Example of an MX record
MX records consist of two parts: the priority and the domain name. For example:
0 mail.EXAMPLE.com
Your MX records are controlled at the company where your Nameservers are pointed. If your domain uses WPOwl nameservers, all modifications to your DNS (including custom MX records) will be made to your WPOwl host panel.
All DNS modifications (including custom MX records) must be made to the company that hosts your nameservers if your domain does not use WPOwl's nameservers. You can set up custom mail DNS records at your external DNS provider using mail DNS information from your WPOwl host panel if you choose to use a standard WPOwl-hosted mail service with a domain using non-WPOwl nameservers.
