Stop domain spoofing in its tracks
Without DMARC, anyone can send emails pretending to be you. This damages your brand reputation and puts your customers at risk.
Prevent hackers from using your domain to send phishing emails. DMARC gives you the power to reject unauthorized emails.
See exactly who is sending email on your behalf. Identify shadow IT and unauthorized third-party senders.
Implementing DMARC is a signal to email providers that you are a legitimate sender, improving your inbox placement.
