Authentication

What does this check?

Our domain health checker scans your DNS records for SPF, DKIM and DMARC configuration issues. These three protocols work together to authenticate your emails and protect your domain from spoofing and phishing attacks.
Deliverability

Why does email authentication matter?

Properly configured email authentication records ensure your emails reach inboxes instead of spam folders. Major email providers like Google and Microsoft require DMARC compliance, making correct configuration essential for email deliverability.
Security

How does DMARC protect your domain?

DMARC prevents unauthorised senders from using your domain to send phishing emails. By setting a DMARC policy, you tell receiving mail servers to reject or quarantine emails that fail authentication checks, protecting your brand and recipients.
Monitoring

How can I monitor my domain health?

Running a one-time check is a great start, but email authentication issues can appear at any time. Our platform continuously monitors your SPF, DKIM and DMARC records and alerts you instantly when something changes. Sign up to get started.
