Email setup 58/100

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.

Authentication

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

SPF alignment: observed emails use a third-party return-path (s5.csa1.acemsa3.com) — SPF passes there but doesn't align with infinitusmail.com, so DMARC has to rely on DKIM alignment.

DKIM alignment: all 59 observed emails sign with a domain aligned with infinitusmail.com (infinitusmail.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

TLS: modern — 100% TLS 1.3 (across 40 sends).

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

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.
