SPF lookups 6/10

SPF / DKIM / DMARC above reflect the last 8 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to proofpoint.com. Policy p=reject means receivers actively block or quarantine spoofed mail.

SPF alignment: all 17 observed emails use a return-path aligned with walmart.com (abmail.em.walmart.com, prod.walmart.com, ib.transaction.walmart.com). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 21 observed emails sign with a domain aligned with walmart.com (em.walmart.com, relay.walmart.com, prod.walmart.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

TLS: 52% TLS 1.3, 48% TLS 1.2 (across 21 sends).

Delivery (last 7 days): 67% under 10 seconds, 0% over 1 minute (across 3 sends).

Confirmed senders

Other SPF authorizations

ESPs this brand has authorized in their SPF record. We confirm them with a green ✓ only after seeing recurring use (3+ emails across 2+ days). Until then they stay here — either we haven't observed any email yet, or we've seen a handful but not enough to call them a regular sender for the brand.

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. Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
