DMARC is an email authentication protocol. It is designed to help email senders and receivers better protect and secure email communications from spam, phishing, and other email-based threats. When an email fails DMARC authentication, it is considered "non-aligned." This means that the email did not come from the domain it claimed to come from, or that the email failed SPF and/or DKIM authentication checks. Non-aligned emails may be blocked or quarantined by the email receiver.

By implementing DMARC, you can help prevent email fraud and phishing attacks, and ensure that your email messages are properly authenticated. As a result, you can protect your reputation and safeguard your customers.

When it comes to email security, DMARC is a must-have. By implementing DMARC, you can help prevent email fraud and phishing attacks, and ensure that your email messages are properly authenticated. As a result, you can protect your reputation and safeguard your customers.

DMARC can also help you improve your email deliverability, as it allows you to specify how unauthenticated messages should be handled. By specifying a policy for unauthenticated messages, you can ensure that your legitimate emails are delivered to the inbox, and reduce the chances of your messages being flagged as spam.

There are three different types of DMARC:

1. None: This means that the sender is not using DMARC at all.

2. Quarantine: This means that the sender is using DMARC, but some of their messages are still getting through to recipients.

3. Reject: This means that the sender is using DMARC, and all of their messages are being blocked by recipients.

If you don't have a DMARC record, email from your domain may be blocked or marked as spam by email providers. This can cause deliverability issues for legitimate email sent from your domain. Additionally, attackers may spoof email from your domain to send phishing or other malicious email, which can damage your reputation and business. It's important to have a DMARC record to help protect your email channel and ensure deliverability of legitimate email.

DMARC, or Domain-based Message Authentication, Reporting & Conformance, is an email authentication protocol that helps protect email senders and recipients from email impersonation. By authenticating email using DKIM and SPF, DMARC adds another layer of security to email messages. DMARC also provides a way for email senders to receive feedback about whether their messages are being delivered successfully and whether any issues were encountered along the way. This feedback can help email senders troubleshoot delivery problems and improve their email deliverability.
