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.

Solid setup, room to improve

Authentication

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

SPF alignment: 67% of observed emails use an aligned return-path (outbound.intercom.mds.co); the rest use third-party paths (flowium.com) where DMARC has to rely on DKIM alignment.

DKIM alignment: all 4 observed emails sign with a domain aligned with mds.co (mds.co). DKIM authenticates the visible From — supports DMARC directly.

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.
