SPF lookups 2/10

SPF / DKIM / DMARC above reflect the last 1 email we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to Agari (Proofpoint). Policy p=reject means receivers actively block or quarantine spoofed mail.

SPF alignment: all 2 observed emails use a return-path aligned with cox.com (em.cox.com). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 5 observed emails sign with a domain aligned with cox.com (em.cox.com, service.cox.com, mc.cox.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 2 sends).

Placement by ESP

Which ESP's emails are landing where. Sorted by spam % so problem senders surface first. Brands using one ESP for marketing and another for transactional often see very different placement profiles per ESP.
