Frequently Asked Questions

The Domain Scanner performs a comprehensive analysis of your domain's email authentication records (SPF, DKIM, DMARC, BIMI), MTA-STS configuration, and other security settings to identify potential issues.

A healthy domain configuration is crucial for email deliverability. It ensures your emails are trusted by receiving servers, prevents spoofing, and maintains a good sender reputation.

It's recommended to scan your domain whenever you make changes to your DNS records or email infrastructure. Regular periodic scans (e.g., monthly) can also help detect any unauthorized changes or issues.

A score of 8 or higher is considered excellent. Scores below 6 indicate potential security vulnerabilities or misconfigurations that should be addressed to improve deliverability and protection.
