Email setup 85/100

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 3/10

SPF / DKIM / DMARC above reflect the last 7 emails we've observed. DMARC policy is read live from DNS.

Authentication

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

DKIM alignment: all 14 observed emails sign with a domain aligned with fsb.org.uk (email.fsb.org.uk). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

TLS: modern — 100% TLS 1.3 (across 9 sends).

Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 4 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.

Dotdigital ✓ 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.
