DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that 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 email messages that fail the DMARC authentication checks.
You can choose between three different policies:
Takes no action on the message and delivers it to the intended recipient.
Marks the message as spam and sends it to the recipient's spam folder. Recipients can review the spam message to identify legitimate messages.
Rejects the messages. With this policy, emails usually return soft bounces.
Adding a DMARC record with a strict policy (quarantine or reject) to your domain or subdomain is a good way to protect it. However, you might encounter the following error message when trying to schedule your email sending:
Why should I authenticate my domain?
If you have a DMARC record with a strict policy and haven't authenticated your domain or subdomain on Brevo, you might experience email deliverability issues with Brevo. Your emails might end up in spam folders or return soft bounces. To send email campaigns with Brevo while having a strict DMARC policy, you have to verify and authenticate your domain by adding the Brevo code and DKIM DNS records to your domain hosting platform.
After verifying and authenticating your domain on Brevo, the error message should have disappeared, and you can safely send your email campaigns with Brevo 🎉.
