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 3 emails we've observed. DMARC policy is read live from DNS.
DMARC enforced with p=reject — receivers actively reject or quarantine spoofed mail. No aggregate reporting destination configured.
SPF alignment: all 3 observed emails use a return-path aligned with 4kdownload.com (mg.4kdownload.com). SPF authenticates the visible From — supports DMARC directly.
DKIM alignment: all 3 observed emails sign with a domain aligned with 4kdownload.com (mg.4kdownload.com). 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.
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.
