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 Postmark DMARC. Policy
p=quarantine means receivers actively block or quarantine spoofed mail.
SPF alignment: 8% of observed emails use an aligned return-path (pm-bounces.emailtooltester.com); the rest use third-party paths (gb.d.sender-sib.com, ga.d.sender-sib.com, af.d.mailin.fr) where DMARC has to rely on DKIM alignment.
DKIM alignment: 100% of observed emails sign with an aligned DKIM key (emailtooltester.com); the rest sign with third-party keys (pm.mtasv.net, msnd1.com) where DMARC has to rely on SPF alignment.
TLS: modern — 100% TLS 1.3 (across 166 sends).
Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 26 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).
CleverReach 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. 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.
| ESP | Emails | Placement | Inbox % | Tabs % | Spam % |
|---|---|---|---|---|---|
| Brevo | 265 | 86.0% | 14.0% | 0.0% | |
