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.
DMARC reports sent to capitaxer.com. Policy
p=reject means receivers actively block or quarantine spoofed mail.
SPF alignment: observed emails use a third-party return-path (amazonses.com) — SPF passes there but doesn't align with capitaxer.com, so DMARC has to rely on DKIM alignment.
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
