SPF / DKIM / DMARC above reflect the last 8 emails we've observed. DMARC policy is read live from DNS.

Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
None — only the primary ESP(s) shown aboveESPs 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.
"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.
No additional ESPs authorized in the brand's SPF beyond the confirmed senders above.

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

Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
