Email setup 73/100

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.

Solid setup, room to improve
Most authentication signals are present. A couple of pieces would tighten things up.

SPF lookups 7/10

SPF / DKIM / DMARC above reflect the last 2 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to Postmark DMARC. Policy p=none is monitor-only — receivers won't act on spoofing yet.

SPF alignment: 94% of observed emails use an aligned return-path (pm-bounces.hikeseo.co, outbound.intercom.hikeseo.co); the rest use third-party paths (kocruj.shared.klaviyomail.com) where DMARC has to rely on DKIM alignment.

DKIM alignment: 94% of observed emails sign with an aligned DKIM key (hikeseo.co); the rest sign with third-party keys (shared.klaviyomail.com) where DMARC has to rely on SPF alignment.

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.

Postmark ✓ 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.

Placement by ESP

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.

Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
