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 3 emails we've observed. DMARC policy is read live from DNS.
DMARC enforced with p=quarantine — receivers actively reject or quarantine spoofed mail. No aggregate reporting destination configured.

DKIM alignment: all 16 observed emails sign with a domain aligned with spectrumemails.com (spectrumemails.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: modern — 100% TLS 1.3 (across 6 sends).

| Folder | Count | Share |
|---|---|---|
| inbox | 13 | 100.0% |
Which ESP's emails are landing where. Sorted by spam % so problem senders surface first.
