Amazon SESAuthentication signals observed in this brand's emails. SPF, DKIM and DMARC are the standard sender-authentication stack — see the DMARC policy below for whether spoofing is actually blocked or just monitored. One-click unsubscribe meets Google & Yahoo's bulk-sender requirements.
SPF / DKIM / DMARC above reflect the last 1 email we've observed. DMARC policy is read live from DNS.
DMARC published as p=none with no rua= reporting — monitor-only, and the sender isn't collecting reports either.
SPF alignment: all 1 observed email use a return-path aligned with earnstar.com (mail.earnstar.com). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: all 1 observed email sign with a domain aligned with earnstar.com (earnstar.com). DKIM authenticates the visible From — supports DMARC directly.
