Email setup 80/100

Authentication 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.

Solid setup, room to improve

Authentication

DMARC reports sent to anitab.org. Policy p=quarantine means receivers actively block or quarantine spoofed mail.

SPF alignment: 60% of observed emails use an aligned return-path (em5605.anitab.org, bounce.email.anitab.org); the rest use third-party paths (amazonses.com) where DMARC has to rely on DKIM alignment.

DKIM alignment: 75% of observed emails sign with an aligned DKIM key (anitab.org); the rest sign with third-party keys (s13.y.mc.salesforce.com) where DMARC has to rely on SPF alignment.

Amazon SES ✓ confirmed SendGrid ✓ confirmed

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.
