DKIM record checker.

Look up a selector's DKIM public key, check its strength, or probe common selectors to find one.

No selector? We'll probe common ones. To find the exact selector, check a real message's DKIM-Signature with the .eml analyzer.

This check is a snapshot. dmarcula watches your domain around the clock, reads the DMARC reports for you, and emails you when something changes. Free, no credit card.
