DMARC - Email's Big Upgrade

Why Deploy DMARC on your domain?

DMARC, developed in 2012, is a new type of email authentication that allows you to not only see how your domain is being used to send email, but also to tell the world to reject illigitimate messages purporting to be from your domain.

To help with understanding and education of DMARC authentication, we've published a few brief videos for a variety of topics, here are a few to get you started:


Ever wonder what happens to an email after it leaves your infrastructure? DMARC allows you to automatically collect data on how email receivers view and treat messages from your organization.

See how all your domains are sending and why some receivers may be rejecting your email.


Deliverability is changing for the better. Instead of guessing how to get your email delivered, all major email receivers are asking senders to make email easy to identify.

This process is called email authentication, and DMARC is the right way to do it.


DMARC is the building block for modern email reputations systems. If you're not sending DMARC-ccompliant email, your reputation is a mish-mash of IP addresses, your ESP, and factors that may be beyond your control.

Take control of your reputation by deploying DMARC across your email, and be judged on the email you send!


DMARC is used today to remove fraud from the email channel. You can benefit from the same anti-phishing controls enjoyed by PayPal, Facebook, Twitter, and lots of others.

dmarcian helps everyone benefit from the strong security provided by DMARC. Once you accurately deploy DMARC, you can tell receivers to quarantine or reject illegitimate email.
