What is a Hostname?
A
hostname is essentially a label assigned to a device connected to a network. In the context of
email marketing, a hostname is crucial as it identifies the mail server responsible for sending and receiving emails on behalf of your domain.
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.
How Does Hostname Affect Email Deliverability?
The hostname can significantly impact
email deliverability. A properly configured hostname that matches your domain’s IP address and passes rDNS checks can enhance your sender reputation. Conversely, a misconfigured hostname can lead to emails being flagged as spam or even being blocked outright.
Common Issues with Hostname in Email Marketing
Some common issues include incorrect DNS settings, mismatched IP addresses and hostnames, and improper SPF, DKIM, and DMARC configurations. These issues can lead to poor deliverability, emails landing in the spam folder, or even being rejected by the recipient's mail server.Best Practices for Managing Hostname in Email Marketing
