Email setup 50/100

SPF lookups 1/10

SPF / DKIM / DMARC above reflect the last 2 emails we've observed. DMARC policy is read live from DNS.

Authentication

No DMARC record published. Domain is not protected against spoofing.

DKIM alignment: all 5 observed emails sign with a domain aligned with marketeris.sk (mail.marketeris.sk). DKIM authenticates the visible From — supports DMARC directly.
