In compliance with Gmail and Yahoo's new requirements for email senders, authenticating your domain with DMARC is now mandatory. We'll explain what a DMARC policy is and how to set it up for your domain.

What is a DMARC policy?

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol. It protects email domains from unauthorized use, such as phishing or spoofing. As a domain owner, you can enforce a policy for your DMARC record to define what should happen to emails that fail DMARC authentication checks.

There are three different policies to choose from:

• none 
  Takes no action on the email and delivers it to the intended recipient. This policy is recommended for those unfamiliar with DMARC setup and is the one provided by Brevo.
• quarantine
  Marks the email as spam and sends it to the recipient's spam folder. This allows recipients to review the spam email and identify legitimate emails.
• reject
  Rejects the emails. With this policy, emails usually return soft bounces.

How to set up a DMARC policy?

DMARC is a complex protocol which is why we only provide the values to set up a DMARC p=none at Brevo:

v=DMARC1; p=none; rua=mailto:rua@dmarc.brevo.com
