Email setup 80/100

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 / DKIM / DMARC above reflect the last 10 emails we've observed. DMARC policy is read live from DNS.

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

SPF alignment: 30% of observed emails use an aligned return-path (bounce.interactive.wsj.com); the rest use third-party paths (cmail19.com, cmail20.com) where DMARC has to rely on DKIM alignment.

DKIM alignment: all 134 observed emails sign with a domain aligned with wsj.com (interactive.wsj.com). DKIM authenticates the visible From — supports DMARC directly.

TLS: modern — 100% TLS 1.3 (across 62 sends).

Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 18 sends).

Other ESPs detected

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.

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.
