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.

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

SPF alignment: observed emails use a third-party return-path (shared-p200-i18.d.sp2-brevo.net, shared-p100-i25.d.sp1-brevo.net, shared-p100-i29.d.sp1-brevo.net) — SPF passes there but doesn't align with wceu.eu, so DMARC has to rely on DKIM alignment.

DKIM alignment: all 10 observed emails sign with a domain aligned with wceu.eu (wceu.eu). DKIM authenticates the visible From — supports DMARC directly.

Where emails landed (Gmail)

Folder distribution across all emails from this brand observed in Gmail inboxes. High inbox % = good deliverability; spam appearances are the headline signal.

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.
