How do I check if I'm compliant?

Checking compliance requires reviewing authentication setup, monitoring complaint rates, and verifying unsubscribe functionality. Gmail Postmaster Tools and Yahoo's sender portal provide compliance indicators for registered domains.

For authentication, use online tools to verify SPF, DKIM, and DMARC records resolve correctly and that sent messages pass authentication checks. Send test messages and examine headers to confirm signatures apply properly.

Monitor complaint rates through provider dashboards and feedback loops. Test one click unsubscribe functionality by examining List-Unsubscribe headers in sent messages and verifying the mechanism works. Many ESPs provide compliance dashboards that aggregate these checks into unified views.
