About This Scan
This assessment evaluates security information that is publicly visible for the domain entered. It does not access your email, read messages, log into your systems, or make changes to your environment.
Results represent externally observable configuration at the time of the scan. Some controls, including DKIM, may not always be fully detectable without analyzing an actual email message.
WHY IT MATTERS
Your domain is part of every business conversation.
- SPF
- Identifies the systems allowed to send email for your domain.
- DKIM
- Adds digital signatures that participating receivers can verify.
- DMARC
- Sets the policy for messages that fail authentication and alignment.
