What is a DMARC record and its uses?

DMARC

Here, in this tutorial, you will understand what exactly is a DMARC record.

Let us know what is a DMARC record.

  • DMARC (Domain-based Message Authentication Reporting and Conformance) is an email validation barrier that protects your company’s email domain from being misused for email spoofing, phishing frauds, and other kinds of cybercrime.
  •  The existing email authentication methods SPF (Sender Policy Framework) and DKIM are influenced by DMARC (Domain Keys Identified Mail).
  •  DMARC adds an important function, reporting. When a domain owner adds a DMARC record to their DNS record, they’ll be able to see who’s sending email on their behalf.

Its Uses:

  • This data can be utilised to obtain more specific information about the email channel.
  • A domain owner can get control over emails sent on his behalf using this information. DMARC can be used to defend your domains from phishing and spoofing attacks.
  • As a website owner, you want to ensure that only emails sent by you will be seen by your visitors or customers.
  • As a result, DMARC is a must-have for any domain owner.
  • If you use DMARC to safeguard your email, email recipients can be confident that an email is genuine and came from you.
  • This has a good effect on email delivery while also preventing others from sending email from your domain.
