Simulate how a receiving mail server evaluates DMARC. Set your SPF/DKIM results, alignment modes, and policy to see exactly what will happen to a message.

presets:

SPF result

SPF envelope-from domain

DKIM result

DKIM signing domain (d=)

DMARC record

Policy (p=)

Subdomain policy (sp=)

DKIM alignment (adkim=)

SPF alignment (aspf=)

This is a simulation based on RFC 7489 rules. Real-world DMARC evaluation by receiving mail servers may differ slightly. Use the SPF, DKIM, and DMARC checker tools to verify your actual published records.
