SPF lookups 6/10

SPF / DKIM / DMARC above reflect the last 10 emails we've observed. DMARC policy is read live from DNS.

Authentication

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

DKIM alignment: all 81 observed emails sign with a domain aligned with hellosign.com (mail.hellosign.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

TLS: 0% TLS 1.3, 100% TLS 1.2 (across 59 sends).

Delivery: fast — 95% of emails in the last 7 days arrive in under 10 seconds (across 38 sends).

Other ESPs detected

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

None — only the primary ESP(s) shown above

Confirmed senders

ESPs 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.

Mailgun ✓ confirmed

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.

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.
