SPF lookups 9/10

SPF / DKIM / DMARC above reflect the last 1 email we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to teachable.com. Policy p=reject means receivers actively block or quarantine spoofed mail.

DKIM alignment: all 5 observed emails sign with a domain aligned with teachable.com (news.teachable.com, tx.teachable.com, m.teachable.com). DKIM authenticates the visible From — supports DMARC directly.

Other ESPs detected

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

Amazon SES 1

Mailgun ✓ confirmed Braze ✓ via SparkPost

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.
