Email setup 80/100

Authentication

DMARC reports sent to DMARC Analyzer (Mimecast). Policy p=quarantine means receivers actively block or quarantine spoofed mail.

SPF alignment: 50% of observed emails use an aligned return-path (bounces.brighthorizons.com); the rest use third-party paths (intuitcloud.onmicrosoft.com) where DMARC has to rely on DKIM alignment.

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

SparkPost ✓ 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.
