Email Security Testing Tool
Test your domain's email security configuration including SPF, DMARC, DKIM, and MX records. Ensure your emails are protected and deliverable.
What We Test
SPF
Sender Policy Framework prevents email spoofing by specifying which mail servers can send emails on behalf of your domain.
DMARC
Provides instructions to email receivers on how to handle emails that fail SPF or DKIM checks.
DKIM
Digital signatures that verify the email hasn't been tampered with during transit.
MX Records
Mail Exchange records that specify which mail servers accept emails for your domain.
