DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication standard for fighting phishing and malware. It’s essentially a third party that sits between your email sender (e.g. company marketing department) and the recipient’s email server. DMARC helps you take control of your company’s email domain by monitoring and reporting on email activities while also setting up policies to handle unwanted emails from third parties.
How does DMARC work?
DMARC works by setting up rules for legitimate and illegitimate email messages sent from your email servers. For example, your company might have several different email servers to send mail to different departments. DMARC can be set up to block emails from servers that do not follow your company’s policies (e.g. sending unsecured emails). DMARC also allows you to reject emails from trusted servers that still contain malicious content (e.g. phishing emails from a hacked server). At the same time, DMARC can allow legitimate emails from servers that follow your company’s policies (e.g. emails from your marketing department).
Benefits of using DMARC
- DMARC helps you stop emails from phishing scams by blocking them or alerting them about their unauthentic nature.
- There are many types of spam emails, but one of the biggest sources of spam comes from bulk emails sent from legitimate sources. DMARC helps you prevent these emails from being sent.
- Your email reputation can affect your brand image. DMARC helps you make sure emails sent from your domain are legitimate.
- One of the biggest dangers of spam filtering is a false positive, an email that should have been delivered but was incorrectly identified as spam. With DMARC, you can avoid false positives by setting thresholds for acceptable email volume.
Why is DMARC important?
DMARC helps you take control of your company’s email domain by monitoring and reporting on email activities while also setting up policies to handle unwanted emails from third parties. DMARC is also important because it can be used with other authentication protocols.
