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 2/10

SPF / DKIM / DMARC above reflect the last 9 emails we've observed. DMARC policy is read live from DNS.

Authentication

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

SPF alignment: all 2 observed emails use a return-path aligned with belonghome.com (outbound.intercom.belonghome.com). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 18 observed emails sign with a domain aligned with belonghome.com (mail.belonghome.com, belonghome.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

TLS: 0% TLS 1.3, 100% TLS 1.2 (across 18 sends).

Delivery (last 7 days): 71% under 10 seconds, 0% over 1 minute (across 7 sends).

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. Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
