Email setup 80/100

SPF lookups 7/10

SPF / DKIM / DMARC above reflect the last 6 emails we've observed. DMARC policy is read live from DNS.

Authentication

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

SPF alignment: 78% of observed emails use an aligned return-path (e.diversesystem.com); the rest use third-party paths (eu-central-1.amazonses.com) where DMARC has to rely on DKIM alignment.

DKIM alignment: all 9 observed emails sign with a domain aligned with diversesystem.com (diversesystem.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 2 sends).

Other ESPs detected

Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).

None — only the primary ESP(s) shown above

Confirmed senders

ESPs we've seen sending email for this brand. Green = confirmed by SPF, sender IP rDNS, or known infra pairing (label shows the source). Grey = observed but not yet confirmed by SPF or PTR.

Amazon SES ✓ confirmed ExpertSender observed

"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.

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.
