What is Reverse DNS Lookup and Its Role in Email Marketing?

Reverse DNS (rDNS) lookup is the process of resolving an IP address back to a hostname. This is crucial in email marketing for validation purposes. Many mail servers perform an rDNS check to verify that the IP address sending the email matches the hostname. If the rDNS lookup fails, your emails might be marked as spam.
