Email setup 72/100

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.

SPF lookups 4/10

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

Authentication

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

SPF alignment: observed emails use a third-party return-path (amazonses.com) — SPF passes there but doesn't align with reviews.co.uk, so DMARC has to rely on DKIM alignment.

DKIM alignment: all 3 observed emails sign with a domain aligned with reviews.co.uk (reviews.co.uk). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 3 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.

Amazon SES ✓ 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.
