DKIM alignment: all 13 observed emails sign with a domain aligned with webinargeek.com (webinargeek.com). DKIM authenticates the visible From — supports DMARC directly.

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.
