Do you often worry about the security of your emails and how to protect them from falling into the hands of online scammers? With the growing number of email phishing attacks, it's more important than ever to ensure a safeguard against these cybercrimes. That's where DMARC comes in handy! In this comprehensive guide, you'll learn all about DMARC, its importance in 365 days, and how it can protect your business from email-based fraud.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email validation system that helps protect your domain from email spoofing and other cyber threats. By implementing DMARC, you can ensure that only legitimate messages sent from your domain reach the recipient's inbox and that all fake emails are either rejected or quarantined.
How DMARC works
- DMARC uses two existing email authentication techniques - SPF (Sender Policy Framework) and DKIM (Domain Keys Identified Mail) to validate the legitimacy of an email.
- When an email is sent from your domain, DMARC first checks if the email has a valid SPF and/or DKIM signature.
- If the signatures are valid, the email can proceed to the recipient's inbox. If not, the email is either rejected or quarantined based on the DMARC policy you've set.
- DMARC will also provide you with reports on which emails passed or failed the DMARC checks, enabling you to further investigate any irregularities or suspicious activities.
Why DMARC is important for your business
- Protection from email fraud: DMARC helps in preventing spoofed emails from reaching the inboxes of your customers, clients, or employees, thus protecting your brand reputation and customers' trust.
- Improved email deliverability: With DMARC in place, ISPs and email servers are more likely to correctly deliver your legitimate emails to the recipients' inboxes without being marked as spam.
- Better visibility: DMARC reports give you insights into who is sending emails on behalf of your domain – both legitimate and fraudulent. This enables you to take proactive measures to secure your email channels and eliminate vulnerabilities.

Steps to implement DMARC 365
- Create a DMARC record with appropriate values for your domain.
- Publish the DMARC record in your domain's DNS.
- Monitor DMARC reports and analyze email delivery performance.
- Adjust your DMARC policy based on your analysis and the results from the reports.
- Keep an eye on emerging threats and stay updated on the latest DMARC best practices to maintain a strong email security posture all year round.
DMARC 365 Example:
Imagine you own an online store that frequently sends promotional emails to its customers. Some cybercriminals have decided to target your customers with phishing emails, pretending to be your store. These phishing emails contain malicious links designed to steal customers' personal information.
Without a DMARC record in place, the phishing emails could easily reach your customers' inboxes, leading to a potential loss of personal data and ultimately harming your store's reputation.
On the other hand, if you implemented DMARC 365 and proactively monitored its functioning, your customers would be protected from these phishing attempts. Your genuine promotional emails would safely reach their inboxes, and the phishing emails sent by cybercriminals would be automatically flagged, quarantined, or rejected.
Congratulations! You now possess the knowledge needed to protect your email domain with DMARC 365.
