Understanding the problem

Why DMARC matters

DMARC builds on SPF and DKIM to control what happens when authentication fails.

Stops spoofing and phishing

Attackers cannot send emails pretending to be your domain once DMARC is enforced.

You control the policy

Choose whether failing emails are monitored, sent to spam, or blocked entirely. You decide.

Full visibility into your sending

DMARC reports show every server sending mail as your domain, including ones you did not authorize.

Required by Gmail and Yahoo

Since 2024, both require DMARC for bulk senders. Missing it directly affects inbox placement.

Take the next step

Stop Domain Spoofing
See Every Sender

DMARC tells receivers what to do when SPF or DKIM fails. Use reports to find every sender, then move from monitor mode to quarantine or reject.
