If you have a business and want to get into email marketing, email authentication is the first step you should take to provide your subscribers with security.

DKIM allows the addition of a digital signature to emails that helps verify the sender’s identity and that the message hasn’t been edited or altered. This prevents email spoofing and any other kinds of email fraud.
Here, the sender has to add a digital signature to the email message and then, the receiver can verify the signature by using the sender’s public key which they’ve published in their DNS zone.
Domain-based Message Authentication, Reporting and Conformance (DMARC)
DMARC combines both SPF and DKIM to offer a unique and unified approach to email authentication. It lets the domain owners decide how they’re going to, or, want to handle the emails that fail authentication.
To apply DMARC, the owners publish the DMARC record in their DNS and decide what to do with emails that feel spammy and fail authentication. DMARC also provides reports of feedback to help owners find and address the authentication issues.
