What is MX Record Validation?
MX Record Validation refers to the process of verifying the
Mail Exchange (MX) records of a domain to ensure that the domain has a valid mail server configured to receive emails. This is crucial in
email marketing to ensure that the emails you send will reach the intended recipients. By validating MX records, you can reduce bounce rates and improve your sender reputation.
Deliverability: Ensuring that your emails are sent to valid domains increases the likelihood that they will reach the recipient's inbox.

Extract the domain part from the email address.
Query the DNS server for the MX records associated with the domain.
