Email Security Check
Comprehensive email security analysis covering SPF, DKIM, DMARC, and MX records.
What is email security?
Email security encompasses multiple authentication protocols that work together to prevent spoofing, phishing, and unauthorised use of your domain. The four key components are SPF (which servers can send), DKIM (cryptographic signatures), DMARC (policy enforcement and reporting), and MX (mail exchange routing).
This tool checks all four components together, giving you a comprehensive view of your email security posture. Weaknesses in any one area can undermine the others, so a holistic check is essential.
