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.
DMARC reports sent to edrone.app. Policy
p=none is monitor-only — receivers won't act on spoofing yet.
SPF alignment: observed emails use a third-party return-path (sparkpost.bounce.edrone.me) — SPF passes there but doesn't align with securedstuff.pl, so DMARC has to rely on DKIM alignment.
DKIM alignment: all 3 observed emails sign with a domain aligned with securedstuff.pl (securedstuff.pl). DKIM authenticates the visible From — supports DMARC directly.
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.
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. 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.

| SparkPost | 3 | 33.3% | 66.7% | 0.0% |
Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
