Authentication

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

SPF alignment: all 3 observed emails use a return-path aligned with blink.com (e.hello.blink.com, e.updates.blink.com). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 2 observed emails sign with a domain aligned with blink.com (hello.blink.com). DKIM authenticates the visible From — supports DMARC directly.

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.
