SPF lookups 8/10

SPF / DKIM / DMARC above reflect the last 4 emails we've observed. DMARC policy is read live from DNS.

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

SPF alignment: all 10 observed emails use a return-path aligned with prohealth.com (mailermmq.prohealth.com, send.prohealth.com). SPF authenticates the visible From — supports DMARC directly.

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

Transport & deliverability

TLS: modern — 100% TLS 1.3 (across 5 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.

ESP	Emails	Placement	Inbox %	Tabs %	Spam %
Klaviyo	1		0.0%	100.0%	0.0%
