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.
SPF / DKIM / DMARC above reflect the last 10 emails we've observed. DMARC policy is read live from DNS.
DMARC reports sent to dmarcian. Policy
p=quarantine means receivers actively block or quarantine spoofed mail.
SPF alignment: 33% of observed emails use an aligned return-path (em4190.nanit.com, mail.nanit.com, mailer4p0.nanit.com); the rest use third-party paths (mandrillapp.com) where DMARC has to rely on DKIM alignment.
DKIM alignment: all 99 observed emails sign with a domain aligned with nanit.com (email.nanit.com, nanit.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: 0% TLS 1.3, 100% TLS 1.2 (across 50 sends).
Delivery: fast — 86% of emails in the last 7 days arrive in under 10 seconds (across 35 sends).
Gmail's own filter showed these warnings to real subscribers in their inbox — independent of SPF/DKIM/DMARC pass/fail status. A consistent pattern often signals reputation issues or brand-impersonation concerns.
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).

"Observed" pills mean we detected emails from these ESPs, but they don't appear in any SPF record we probed. They may still be properly authorized — sending infrastructure can live on subdomains we haven't seen yet, or use IP-listing instead of include: directives.
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.

Which ESP's emails are landing where. Sorted by spam % so problem senders surface first.
