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 10 emails we've observed. DMARC policy is read live from DNS.
DMARC reports sent to monday.com. Policy
p=reject means receivers actively block or quarantine spoofed mail.
SPF alignment: 90% of observed emails use an aligned return-path (em8841.monday.com, emails.monday.com, em1208.euc1.monday.com); the rest use third-party paths (collab360marketing.com) where DMARC has to rely on DKIM alignment.
DKIM alignment: all 231 observed emails sign with a domain aligned with monday.com (monday.com, euc1.monday.com, learn.mail.monday.com). DKIM authenticates the visible From — supports DMARC directly.
VMC issued by: entrust.
TLS: modern — 88% TLS 1.3 (across 123 sends).
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 69 sends).
Gmail's own filter showed these warnings to real subscribers in their inbox — independent of SPF/DKIM/DMARC pass/fail status. A consistent pattern often signals reputation issues or brand-impersonation concerns.
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
Mailgun 1ESPs 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.

Which ESP's emails are landing where. Sorted by spam % so problem senders surface first.
