DMARC monitoring and reporting tool

DMARC monitoring tracks the use of your domain in real-time, helping to troubleshoot deliverability issues and protect your account against unauthorized activity.

Why you need a DMARC reporting tool

DMARC reporting provides a framework to identify email deliverability issues and enables you to review content sent from your domain and gain insights into failed email delivery. It also helps to increase security by allowing you to identify unauthorized domain use and choose which email sources to authorize.

Frequently Asked Questions

How do I monitor DMARC?

To start DMARC monitoring you must first implement a DMARC record in your domain’s DNS with a valid feedback email so that you can receive DMARC reports from ISPs. You can also add your domain to a DMARC monitoring tool, like MailerCheck, so that it can receive reports and monitor domain activity on your behalf, notifying you of deliverability issues or suspicious activity.

Alternatively, you can monitor DMARC manually, which involves receiving raw reports from ISPs. Depending on your sending volume, you may be interested in having an app that does the analysis work for you! Learn more about DMARC reports.

Is DMARC free?

You can implement a DMARC record on your domain's DNS for free. With MailerCheck, you can monitor 1 domain as part of the free subscription.

What is the difference between the DMARC reports?

There are two types of DMARC reports—forensic and aggregate. Forensic reports contain information about individual email messages that fail authentication. Aggregate reports contain information about all emails that go through email authentication. MailerCheck users aggregate reports for its analysis, as forensic reports are currently not widely provided by mailbox providers.

What does a DMARC report tell me?

A DMARC report tells you sending activity of your domain, including sending source IPs, email authentication passes and failures, and the action taken by ISPs in the event your email authentication fails. The reports help you to understand why the email was accepted, rejected or quarantined by the receiving ISP by analyzing the audits done.

What is a DMARC failure?

A DMARC failure means your email message failed SPF and DKIM email authentication.
