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 tinuiti.com. Policy
p=quarantine means receivers actively block or quarantine spoofed mail.
SPF alignment: 88% of observed emails use an aligned return-path (bounce.tinuiti.com, email.cps.tinuiti.com, atlassian-bounces.tinuiti.com); the rest use third-party paths (amazonses.com) where DMARC has to rely on DKIM alignment.
DKIM alignment: all 391 observed emails sign with a domain aligned with tinuiti.com (tinuiti.com, email.tinuiti.com, cps.tinuiti.com). DKIM authenticates the visible From — supports DMARC directly.
TLS: modern — 90% TLS 1.3 (across 192 sends).
Delivery: fast — 94% of emails in the last 7 days arrive in under 10 seconds (across 64 sends).
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).

✓ confirmed
"Observed" pills mean we detected emails from these ESPs, but they don't appear in any SPF record we probed. They may still be properly authorized — sending infrastructure can live on subdomains we haven't seen yet, or use IP-listing instead of include: directives.
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. Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
