Email setup 85/100

Authentication

DMARC reports sent to wappalyzer.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 wappalyzer.com, so DMARC has to rely on DKIM alignment.

DKIM alignment: all 1 observed email sign with a domain aligned with wappalyzer.com (wappalyzer.com). DKIM authenticates the visible From — supports DMARC directly.

Amazon SES ✓ 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.

ESP activity over time

Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
