Domain Authentication

How to authenticate my domain

Domain Authentication is a mechanism that verifies the email from the point of its origin by validating the email sender. It checks emails to rule out any possibility of spamming or spoofing thereby protecting the sender's good reputation. Authenticating your domain allows for smooth transfer of emails through spam filters and into your recipient's inbox.

Domain authentication methods:

SPF: This method allows you to specify the mail servers (IP addresses) which can send emails on your behalf. This can be done by publishing the TXT record in your domain's DNS settings. Learn More

DKIM: This is a more advanced method used widely by email service providers. It allows the senders to authenticate their campaigns by including a digital signature in the email header. This can be done by publishing the TXT record in your domain's DNS settings. Learn More
