Complying with DMARC policy can also indirectly enhance email deliverability.  Here are a few ways DMARC can help maintain a decent sender domain reputation:

• The protocol prevents emails originating in unrecognized servers from reaching inboxes. As a result, DMARC can protect your brand and your domain's reputation. 
  
• It provides additional transparency about the number of messages from domain pass-through authentications.
  
• It helps the sender inform receiving systems about how to handle incoming unauthenticated emails.
  

If you're interested in complying with DMARC, Zoho Marketing Automation allows you to authenticate your domain using SPF and DKIM. Setting up these policies are required steps for adhering to DMARC.

SPF – Sender Framework Policy

This is a simple email validation system that detects spoofing and is also the first step in email authentication. SPF provides a mechanism to note which email servers are authorized to send emails on behalf of a particular domain.

DKIM – Domain Keys Identified Mail

This authentication method ensures that emails aren't tampered with during transmission. DKIM associates a domain with an email message by affixing a digital signature to the domain name. Verification is then carried out through the signer's public key published in the Domain Name System (DNS).

SPF and DKIM authentication are simple steps marketers can take toward DMARC compliance. Contact your email service provider for additional assistance with setting up a DMARC policy.
