Email setup 53/100

SPF lookups 7/10

SPF / DKIM / DMARC above reflect the last 7 emails we've observed. DMARC policy is read live from DNS.

Authentication

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

SPF alignment: 29% of observed emails use an aligned return-path (k3.klaviyo.circlesportswear.com); the rest use third-party paths (rxtqed.shared.klaviyomail.com, send.ksd1.klaviyomail.com) where DMARC has to rely on DKIM alignment.

DKIM alignment: 29% of observed emails sign with an aligned DKIM key (klaviyo.circlesportswear.com); the rest sign with third-party keys (shared.klaviyomail.com, ksd1.klaviyomail.com) where DMARC has to rely on SPF alignment.

Confirmed senders

Klaviyo ✓ confirmed

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.

Folder distribution across all emails from this brand observed in Gmail inboxes. High inbox % = good deliverability; spam appearances are the headline signal.

Folder	Count	Share
inbox	2	100.0%

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.
